Drawing an angle of the given measure
Example Draw ∠ABC of measure 70°.
B is the vertex of∠ABC and BA and BC are its arms.

1. First draw arm BC with a ruler.

Maharashtra Board Class 5 Maths Solutions Chapter 6 Angles Problem Set 25

Teacher : Have Rahul and Sayali drawn the angles correctly?
Shalaka : Sir, Rahul’s angle is wrong. Sayali’s angle is correct.
Teacher : Why is Rahul’s angle wrong?
Rahul : I counted 10, 20, 30…from the left and drew the angle at 80.
Teacher : Rahul measured the angle from the left. Under the baseline on the left of Q, there is nothing. The arm of the angle is on the right of Q. Therefore, the point should have been marked 80° counting from the right side, that is, on the side on which point R lies.

प्रश्न 6.
स्वमत.

(अ) ‘माणसातील ठरावीक मनोवृत्तीची पुनरावृत्ती वारंवार होत असते’, हे पाठाच्या आधारे स्पष्ट करा.
उत्तर :
माणसाच्या स्वभावाची एक गंमतच आहे. आपल्या मुलाने सकाळी लवकर उठावे, व्यायाम करावा, नियमित अभ्यास करावा. त्याने चांगल्या मुलांचीच संगत धरावीः परीक्षेत जास्तीत जास्त गुण मिळवावेत… वगैरे वगैरे, असे प्रत्येक आईबाबांना वाटते. पण या आईबाबांनी त्यांच्या तरुणपणी असे काहीही केलेले नसते. त्या काळात त्यांच्या आईबाबांनी घरलेले असले आग्रह यांनी उधळून लावले होते. मात्र हे आजच, आधुनिक काळातच, घडते असे नाही. जगभर सर्व मानवी समाजांत हेच घडत आलेले आहे. जन्म, बालपण, तारुण्य, वार्धक्य आणि नंतर मृत्यू हे चक्र अव्याहत पृथ्वीच्या निर्मितीपासूनच चालू आहे. प्रत्येकजण स्वतःच्या जागेवरून जगाकडे बघत असतो. तिथून जग जसे दिसते, तसे आणि तेवढेच खरे आहे, असे तो मानतो. म्हणून प्रत्येक पिढीत ते आणि तसेच घडत राहते.

(आ) गवताच्या पात्याच्या ठिकाणी तुम्ही असता, तर तुम्ही पानाला काय उत्तर दिले असते?
उत्तर :
मी गवतपाते असतो, तर गळून पडणाऱ्या पानाला पुढीलप्रमाणे माझे म्हणणे सांगितले असते :

“आजोबा, आपण दोघेही अकारण भांडत आहोत. काय झाले ते पाहा. तुम्ही गिरक्या घेत घेत खाली आलात. त्या वेळी खूप आवाज झाला आणि माझी झोपमोड झाली. मला राग आला आणि तुम्हांला मी रागाने लागेल असे काहीतरी बोललो. तुम्हीसुद्धा मला चिडखोर बिब्बा म्हणालात, मला अरसिक म्हणालात. पण मी थोडा अंतर्मुख झालो. विचार केला. माझ्या लक्षात आले की आपण चुकीच्या कारणाने भांडत आहोत. आपल्या दोघांचेही दृष्टिकोन भिन्न आहेत. त्यामुळे आपले विचार भिन्न आहेत, आपणा प्रत्येकाला स्वत:चेच बरोबर आहे, असे वाटते. समोरचा चुकीचा आहे असे वाटते.

आता हेच पाहा ना. तुम्ही जमिनीपासून उंचावर राहता. तुम्हांला दूरदूरचा परिसर उंचावरून दिसतो. भोवतालच्या परिसराच्या दर्शनाचा आनंद घेता येतो. त्यामुळे तुम्हाला तुम्ही श्रेष्ठ आहात असे वाटते. आम्ही मातीत लोळत राहतो. म्हणून आम्ही कमी दर्जाचे आहोत, असे तुम्हाला वाटते. पण आजोबा, आम्ही आत्ता, या क्षणी मनसोक्त जगतो. तुम्ही उदयाचा विचार करीत राहता आणि आजचा आनंद गमावता. आपण दोघेही जण आपापल्या जागी बरोबर आहोत, आपण दुसऱ्याची स्थिती लक्षात घेतली पाहिजे. मग आपल्याला दोघांच्याही भूमिका कळतील आणि आपण भांडत बसणार नाही.

Maharashtra Board Class 10 Marathi Solutions Chapter 7 गवताचे पाते 1

आता हे सगळे राहू दया. तुम्ही सांभाळून सांभाळून चाला. स्वत:च्या प्रकृतीला जपा.

(इ) गवताचे पाते व पान यांच्या स्वभाववैशिष्ट्यांत बदल झाला आहे, अशी कल्पना करून कथेचे पुनर्लेखन करा.
उत्तर :
हिवाळा नुकताच सुरू झाला होता. झाडावरून एकामागून एक पिकलेली पाने गळून पडू लागली.
पट… पटः.. पट…
त्यांचा तो पट… पट… पट… असा कर्णकटू आवाज …

तो आवाज ऐकून धरणीमातेच्या कुशीत झोपी गेलेले एक चिमणे गवताचे पाते जागे झाले. गिरक्या खात खात जमिनीवर येणाऱ्या एका पानाला ते म्हणाले, “अहो आजोबा, आजोबा, केवढ्याने पडलात! लागलंबिगलं तर नाही ना?”

पानाला बरे वाटले. प्रेमळपणे म्हणाले, “काय रे बाळा ? तुला त्रास झाला का रे?”

“छे, छे, आजोबा. तुम्ही ठीक आहात ना?”

“काय सांगू बाळा! इतका झकास तरंगत येताना सारखे वाटत होते की असेच खूप वेळ सुखाने तरंगत राहावे. पण आता वय झाले ना! काय करणार?”

“असं का बोलता? वय झालं म्हणता, पण तरुणांपेक्षाही तुमचे मन – तरुण आहे. किती आनंदात आहात तुम्ही!”

हे ऐकत ऐकत ते पान आनंदाने मातीत मिसळले.

ते पन्हा जागे झाले, ते वसंताच्या संजीवक स्पर्शाने! त्या स्पर्शात E विलक्षण जादू होती. त्या जादूने आता त्या पानाचे रूपांतर गवताच्या चिमुकल्या पात्यात झाले होते. पुन्हा हिवाळा आला. पाते थंडीने कुडकुडत होते. ते धरणीमातेच्या कुशीत लपू लागले, झोपू लागले. पण पुन्हा पुन्हा त्याची झोपमोड होऊ लागली. जिकडेतिकडे झाडांवर पाने सळसळत होती… पट पट असा आवाज करीत पृथ्वीवर पडत होती!

ते गवताचे पाते लगबगीने उठले. स्वतःशीच पुटपुटले. आज दुसरे आजोबा खाली आले वाटतं. चला, चला. पटापट जायला हवं. एखादया आजोबांना मदतीची गरज असेल कदाचित!

प्रश्न 7.
खाली दिलेल्या रूपक कथेचा भावार्थ तुमच्या शब्दांत लिहा.
“…एक विचारू?”
उगवून नुकतेच काही दिवस झालेलं रोप लगतच्या महावृक्षाला म्हणाले.
“हं.
“मलाही तुमच्यासारखं मोठं व्हायचंय… पण..”
“पण माझ्या सावलीखाली आता ते शक्य नाही, हो ना?”
“…हो.” “अरे! कितीतरी लहान लहान झाडंही खूप सुंदर असतात, आणि इतक्या..”
“पण वाढणं देखील सुंदरच असेल ना?”
“हो!
आणि इतक्या उंचीवर आता खरं तर ही लहान झाडंच जास्त सुंदर दिसतात…”
…आणि महावृक्षाला दूरवर जंगलातून वाट काढीत येणारा एक लाकूडतोड्या दिसला!

– (गुलमोहर)

(टीप – रूपक कथेचा भावार्थ परीक्षेकरिता समाविष्ट केलेला असल्याने तोही पाठाचा भाग म्हणून अभ्यासावा.)
उत्तर :
रोप-वृक्षाची ही कथा प्रत्यक्ष जीवनात वेगवेगळ्या रूपांत अवतरताना दिसते. लहान मुलांना मोठे व्हावेसे वाटते. मोठ्या माणसांना काहीही करण्याचे, कुठेही जाण्याचे स्वातंत्र्य असते. मुलांवर बंधने असतात. थोडे बारकाईने पाहिले तर मोठ्यांना लाभणारे स्वातंत्र्य प्रामक असते. मोठ्यांना पोट भरण्यासाठी कामधंदा करावा लागतो. या काळात स्वातंत्र्य बाजूला ठेवावे लागते. मोठ्या माणसांना कायदेकानून, नीती-नियम पाळावे लागतात. पैसा खूप मिळाल्यावर सर्व सुखे उपभोगता येतील, असे सर्वांना वाटत असते. प्रत्यक्षात मात्र स्थिती उलटी असते. खूप पैसे मिळाल्यावर ते पैसे सुरक्षित ठेवण्याच्या चिंतेने माणूस घेरला जातो. रस्त्याच्या फुटपाथवर झोपणाऱ्या माणसाला कोणी चोर येऊन चोरी करील, अशी भीती नसते. पण बंगला बांधलेला माणूस सभोवती भक्कम भिंत बांधून घेतो. दारावर पहारेकरी ठेवतो. याचा अर्थ खूप पैसे मिळाल्यावर सुख मिळते हे खरे नाही.

कृती ४ : (स्वमत / अभिव्यक्ती)

प्रश्न 1.
तरुण पिढी व वडील पिढी यांची स्वभाववैशिष्ट्ये पाठाच्या आधारे लिहा.
उत्तर :
तरुण पिढीचे नेहमी असेच असते. आत्ता या क्षणी. जे दिसते, वाटते, तेच खरे. वर्तमानकाळ हाच खरा. उदया-परवा काय होईल ते महत्त्वाचे नाही. जे जे वाटते ते ते उत्स्फूर्तपणे करावे. वडील पिढीला हे असे वागणे पटत नाही. आणि म्हणून तरुणांना वडील पिढीचा अडथळाच वाटतो. त्यांची कटकट वाटते.

वडील पिढीला वाटते की, तरुण पिढी फक्त मौजमजा करण्यात, सुखविलासात लोळण्यात धन्यता मानते. आयुष्याचा खरा अर्थ या तरुणांना कळलेला नसतो. मात्र, आपण तरुण असताना काय करीत होतो, हे प्रौढांना आठवत नाही. किंबहुना ते लक्षात घ्यायची त्यांची तयारीच नसते. नेमके हेच आता तरुण असलेल्यांच्या बाबतीतही घडते. वडील पिढीविरुद्ध तक्रार करणारे तरुण जेव्हा आईबाबा होतात, तेव्हा ते स्वतःच्या मुलांशी वडील पिढीप्रमाणेच वागतात. म्हणजे ‘येरे माझ्या मागल्या!’ असे असूनही कोणीही वास्तव शोधण्याचा प्रयत्न करीत नाही.

गवताचे पाते Summary in Marathi

पाठाचा आशय एका गवताच्या पात्याची ही कथा आहे. गवताच्या चिमुकल्या पात्यासारखीच कथा ही चिमुकलीच आहे.

हिवाळ्याचे दिवस होते. गवताचे पाते धरणीमातेच्या कुशीत गाढ निद्रा घेत होते. ते गोड गोड स्वप्नांच्या सुखद लहरींवर निवांत तरंगत होते. तेवढ्यात झाडावरून पिकलेली पाने पटापटा पडू लागली. जमिनीवर आपटताना सर्व पानांचा पट-पट-पट असा एकत्रित होणारा आवाज आसमंत व्यापून टाकत होता. तो संपूर्ण आवाज इतका कर्णकटू होता की त्या अप्रसन्न आवाजाने चिमुकल्या गवतपात्याची झोपमोड झाली. शिवाय, ज्या सुखस्वप्नांत ते पार ‘डुंबत होते, त्या सुखस्वप्नांचा चुराडा झाला. या गोष्टीचा त्या गवतपात्याला खूप संताप आला, त्या पात्याने संतापाच्या भरात गळणाऱ्या पानांना भरपूर सुनावले. त्याच्या मते, गळणारी पाने कटकट करतात. त्यांच्या आवाजाच्या दंग्याने माझा आनंद नष्ट होतो.

त्यावर गळणाऱ्या पानाने त्या पात्याला क्षुद्र ठरवले. जमिनीवर लोळणाऱ्या पात्याला उंच झाडावर सळसळण्यातला उच्च दर्जाचा आनंद कधीच कळणार नाही. पाते क्षुद्र पातळीवरच जगत राहणार, असा गळणाऱ्या पानाचा दावा होता.

गळणारे पान थोड्याच अवधीत मातीत मिसळून गेले. त्याच्या कणांमधून एका नवीन गवताच्या पात्याने जन्म घेतला, ते आनंदाने डोलत राहिले. थोड्याच दिवसांत हिवाळा आला. ते नवीन जन्मलेले पाते थंडीने कुडकुडू लागले. ऊब मिळवण्यासाठी ते धरणीमातेच्या कुशीत शिरले आणि हळूहळू झोपी गेले. झोपेत ते सुखस्वप्नांच्या लहरींवर आनंदाने तरंगू लागले. पण पडणाऱ्या पानांच्या गदारोळामुळे त्याची झोपमोड झाली. त्याची सुखस्वप्ने भंग पावली. आता ते पाते गळणाऱ्या पानांना संतापाने दूषणे देऊ लागले.

रूपककथेतून सुचवलेला अर्थ या रूपककथेतून माणसांचा स्वभाव अत्यंत सुंदर रितीने व्यक्त केला गेला आहे. या कथेत काय घडते पाहा. झाडावरून गळून पडणाऱ्या पानाला आपण उच्च स्थानावर राहतो आणि पाते क्षुद्र पातळीवर राहते. आपण उच्च दर्जाचे आहोत आणि गवतपाते मात्र अत्यंत खालच्या दर्जाचे आहे, असे वाटते. याउलट गवतपात्याच्या बाबतीत घडते. आपण खूप सुखी समाधानी जीवन जगत आहोत, आपण भाग्यवान आहोत आणि म्हणून उच्च दर्जाचे आहोत. जीवनातल्या सुखाची गोडी त्या कटकट्या, किरकिऱ्या पानाला. कधीच कळू शकणार नाही, असे त्या गवतपात्याला वाटते.

गळून पडलेले पान मातीत मिसळते आणि त्या पानातूनच नवीन गवतपाते निर्माण होते. आता या गवतपात्याला (म्हणजेच पूर्वीच्या पानाला) गळणाऱ्या पानांचा राग येतो. त्याला गळणारी पाने कटकटी, किरकिरी आणि म्हणून जगण्यातला आनंद न कळणारी आहेत, असे वाटते.

सर्व माणसे केवळ स्वतःच्या नजरेतूनच सर्व जगाचे मूल्यमापन करतात. मुलांना आपले आईवडील कटकटी वाटतात. तर, मुलांनी ताळतंत्र सोडला आहे, असे आईवडिलांना वाटते. आपण तरुणपणी कसे वागलो, हे आईवडील विसरतात. आता तरुण असलेली मुले मोठेपणी स्वतःच्या आईवडिलांसारखे वागतात. एकंदरीत, सर्व मानवी समाजात हे असेच घडते.

Using letters
Symbols are frequently used in mathematical writing. The use of symbols makes the writing very short. For example, using symbols, ‘Division of 75 by 15 gives us 5’ can be written in short as ‘75 ÷ 15 = 5’. It is also easier to grasp.

Letters can be used like symbols to make our writing short and simple.

While adding, subtracting or carrying out other operations on numbers, you must have discovered many properties of the operations.

Maharashtra Board Class 5 Maths Solutions Chapter 16 Preparation for Algebra Problem Set 55

For example, what properties do you see in sums like (9 + 4), (4 + 9)?

The sum of any two numbers and the sum obtained by reversing the order of the two numbers is the same.

Now see how much easier and faster it is to write this property using letters.

  • Let us use a and b to represent any two numbers. Their sum will be ‘a + b’.

Changing the order of those numbers will make the addition ‘b + a’. Therefore, the rule will be : ‘For all values of a and b, (a + b) = (b + a).’

Let us see two more examples.

  • Multiplying any number by 1 gives the number itself. In short, a × 1 = a.
  • Given two unequal numbers, the division of the first by the second is not the same as the division of the second by the first.

In short, if a and b are two different numbers, then (a ÷b) ≠ (b ÷a).

Take the value of a as 8 and b as 4 and verify the property yourself.

Maharashtra State Board Class 5 Maths Solutions Chapter 16 Preparation for Algebra Problem Set 54

Question 1.
Using brackets, write three pairs of numbers whose sum is 13. Use them to write three equalities.
Answer:
(7 + 6), (8 + 5), (9 + 4). since 7 + 6
= 13,8 + 5
= 13, 9 + 4
= 13.

(7 + 6)
= (8 + 5), (7 + 6)
= (9 + 4) or (8 + 5)
= (9 + 4).

Maharashtra Board Class 5 Maths Solutions Chapter 16 Preparation for Algebra Problem Set 54

Question 2.
Find four pairs of numbers, one for each of addition, subtraction, multiplication and division that make the number 18. Write the equalities for each of them.
Answer:
(9 + 9), (20 – 2), (9 x 2), (36 ÷ 2).
since 9 + 9
= 18, 20 – 2
= 18, 9 x 2
= 18 and 36 + 2
= 18, so (9 + 9)
= (20 – 2)
= (9 x 2)
= (36 ÷ 2).

Inequality
The values of 7 + 5 and 7 × 5 are 12 and 35 respectively. It means that they are not equal. To represent ‘not equal’, the symbol ‘≠’ is used.

To show that (7 + 5) and (7 × 5) are not equal, we write (7 + 5) ≠ (7 × 5) in short.

This kind of representation is called an ‘inequality’.

(9 – 5) ≠ (15 ÷ 3) means that the expressions (9 – 5) and (15 ÷ 3) are not equal.

If two expressions are not equal, one of them is greater or smaller than the other.

To show greater or lesser values, we use the symbols ‘<’ and ‘>’. Therefore, these symbols can also be used to show inequalities.

Maharashtra Board Class 5 Maths Solutions Chapter 16 Preparation for Algebra Problem Set 54

The value of (9 – 5) is 4 and the value of (15 ÷ 3) is 5. 4 < 5, so the relation between (9 – 5) and (15 ÷ 3) can be shown as (9 – 5) < (15 ÷ 3) or (15 ÷ 3) > (9 – 5).

Fill in the boxes between the expressions with <, = or > as required.

(1) (9 + 8) [ ] (30 ÷ 2)
9 + 8 = 17,
30 ÷ 2 = 15
17 > 15
Therefore (9 + 8) [ > ] (30 ÷ 2)

(2) (16 × 3) (4 × 12)
16 × 3 = 48,
4 × 12 = 48,
48 = 48
Therefore (16 × 3) [ = ] (4 × 12)

(3) (16 – 5) [ ] (2 × 7)
16 – 5 = 11,
2 × 7 = 14,
11 < 14
Therefore (16 – 5) [ < ] (2 × 7)

Maharashtra Board Class 5 Maths Solutions Chapter 16 Preparation for Algebra Problem Set 54

Write a number in the box that will make this statement correct.
(1) (7 × 2) = ( [ ] – 6)

The value of the expression 7 × 2 is 14, so the number in the box has to be one that gives 14 when 6 is subtracted from it. Subtracting 6 from 20 gives us 14.

Therefore (7 × 2) = ( [ 20 ] – 6 )
(2) (24 ÷ 3) < (5 + [ ] )
The value of the expression 24 ÷ 3 is 8, so the number in the box has to be such that when it is added to 5, the sum is greater than 8.

Now, 5 + 1 = 6, 5 + 2 = 7, 5 + 3 = 8. So the number in the box has to be greater than 3.

Therefore, writing any number like 4, 5, 6 … onwards will do. It means that this problem has several answers. (24 ÷ 3) < (5 + [ 4 ] ) is one among many answers. Even if that is true, writing only one answer will be enough to complete this statement.

Question 2.
If the cost of 1 sq m of a plot of land is 900 rupees, find the total cost of a plot of land that is 25 m long and 20 m broad.
Solution:
Area of the rectangular plot
= length x breadth
= 25 x 20
= 500 sq.m.

Cost of the plot of land
= Area of the plot x rate

= 16 cm

Area of a square = side x side
= 4 x 4
= 16 sq.cm.

Perimeter of a rectangle
= 2 x length + 2 x breadth
= 2 x 8 + 2 x 2
= 16 + 4
= 20 cm

Area of a rectangle
= length x breadth
= 8 x 2
= 16 sq.cm.

Formula for the perimeter of a rectangle

Maharashtra Board Class 5 Maths Solutions Chapter 12 Perimeter and Area Problem Set 48 6
Perimeter = length + breadth + length + breadth Opposite sides of a rectangle are of the same length.
So, the perimeter of a rectangle
= twice the length + twice the breadth
= 2 × length + 2 × breadth

Maharashtra Board Class 5 Maths Solutions Chapter 12 Perimeter and Area Problem Set 48

Perimeter of a rectangle = 2 × length + 2 × breadth

Example : The length of the rectangle below is 7 cm and its breadth, 3 cm. Let us find its perimeter.
Maharashtra Board Class 5 Maths Solutions Chapter 12 Perimeter and Area Problem Set 48 7

Perimeter of rectangle PQRS = 2 × length + 2 × breadth
= 2 × 7 + 2 × 3
= 14 + 6
= 20
Therefore, the perimeter of the rectangle is 20 cm.

Formula for the perimeter of a square

Maharashtra Board Class 5 Maths Solutions Chapter 12 Perimeter and Area Problem Set 48 8 The lengths of all the sides of a square are equal. Therefore, the perimeter of a square = four times the length of one of its sides.

Perimeter of a square = 4 × the length of one side

Example : The length of one side of a square is 6 cm. Find its perimeter. The perimeter of a square is four times the length of one side.
Maharashtra Board Class 5 Maths Solutions Chapter 12 Perimeter and Area Problem Set 48 9
Perimeter of a square = 4 × length of one side
= 4 × 6
= 24

Maharashtra Board Class 5 Maths Solutions Chapter 12 Perimeter and Area Problem Set 48

Therefore, the perimeter of the square is 24 cm.

Word problems

Example (1) The length of a rectangular park is 100 m, while its width is 80 m. What is its perimeter?

Perimeter of the rectangle = 2 × length + 2 × breadth
= 2 × 100 + 2 × 80
= 200 + 160
= 360

The perimeter of the rectangular park is 360 m.

Example (2) How much wire will be needed to put a triple fence around a square plot with side 30 m? What will be the total cost of the wire at ₹ 70 per metre ?

To put a single fence around the square plot, we need to find its perimeter.

Perimeter of a square = 4 × length of one side = 4 × 30 = 120

The perimeter of the square plot is 120 metres. Since the fence is to be a triple fence, we must triple the perimeter.

120 × 3 = 360 m of wire will be needed.

Now let us find out how much the wire will cost. One metre of wire costs ₹ 70.

Therefore, the cost of 360 m of wire will be 360 × 70 = 25, 200.

Maharashtra Board Class 5 Maths Solutions Chapter 12 Perimeter and Area Problem Set 48

The total cost of wire for putting a triple fence around the plot will be ₹ 25, 200.
