Q2. Fill in the blanks:

a) 10 less than 34 is ……………..

b) 53 – 20 = …………….

c) 11 more than 31 is ……………..

d) 11 less than 66 is ……………..

e) 62 + 13 = …………….

f) 23 less than 89 is ……………..

g) 10 and 40 more is ……………..

h) 9 added to 28 gives ……………..

i) The sum of 9 and 44 is ……………..

j) Reducing 98 by 34 gives ……………..

k) 4 and 37 more is ……………..

l) Take 35 away from 83. We get ……………..

Ans.

a) To find 10 less than 34, from 34 take one jump downward.

So, 10 less than 34 is 24.

b) To find 53 – 20, from 53 take two jumps

`

So, 53 – 20 = 33

c) To find 11 more than 31, from 31 take one jump upward and then one step forward.

So, 11 more than 31 is 42.

d) To find 11 less than 66, from 66 take one jump downward and then one step backward.

So, 11 less than 66 is 55.

e) To find 62 + 13, from 62 take one jump upward and then 3 steps forward as:

62 + 13 = 62 + 10 + 3

= 72 + 3

= 75

So, 62 + 13 = 75

f) To find 23 less than 89, from 89 take 2 jumps downwards and then 3 steps backward as:

89 – 23 = 89 – 20 – 3

= 69 – 3

= 66

So, 23 less than 89 is 66

g) To find 10 and 40 more, from 10 take 4 jumps 4 upward.

So,10 and 40 more is 50.

h) To find 9 added to 28, from 28 take 1 jump upward and then 1 step backward.

So,9 added to 28 gives 37.

i) To find the sum of 9 and 44, from 44 take 1 jump upward and then 1 step backward as:

9 + 44 = 44 + 10 – 1

= 54 – 1

= 53

So, the sum of 9 and 44 is 53.

j) To reduce 98 by 34, from 98 take 3 jumps downward and then 4 steps backward.

98 − 34 = 98 −30 − 4

= 68 − 4

= 64

So, reducing 98 by 34 gives 64.

k) To find 4 and 37 more, from 4 take 4 jumps upward and then 3 steps backward.

4 + 37 = 4 + 40 − 3

= 44 − 3

= 41

So,4 and 37 more is 41.

l) To takeaway 35 from 83, from 83 take 3 jumps downward and then 5 steps backward.

83 – 35 = 83 – 30 – 5

= 53 – 5

= 48

So, take 35 away from 83 results in 48.

Q 3 : Fill in the blanks

a) 37 + 9 = __

b) 65 – 30 = __

c) _ = 87 – 30

d) __= 46 + 21

e) 66 – __ = 11

f) 36 = _ + 9

g) 45 + _ = 99

h) _ + 26 = 75

i) 40 + __ = 76

j) 98 = _ + 50

k) __ – 21 = 35

l) 57 – _ = 20

Ans. The shortcut calculations are shown below.

a) 37 + 9 = 37 +10 – 1

= 47 − 1

= 46

b) 65 − 30 = 60 – 30 + 5

= 30 + 5

= 35

c) 87 – 30 = 80 – 30 + 7

= 50 + 7

= 57

d) 46 + 21 = 46 + 20 + 1

= 66 + 1

= 67

e) To find the number in the blank space subtract 11 from 66 as:

66 – 11 = 66 – 10 – 1

= 56 – 1

= 55

Hence, 66 – 55 = 11

f) To find the number in the blank space, subtract 9 from 36 as:

36 – 9 = 36 – 10 + 1

= 26 + 1

= 27

Hence, 36 = 27 + 9

g) To find the number in the blank space, subtract 45 from 99 as:

99 – 45 = 99 – 40 – 5

= 59 – 5

= 54

Hence, 45 + 54 = 99

h) To find the number in the blank space, subtract 26 from 75 as:

75 – 26 = 75 – 20 – 6

= 55 – 6

= 49

Hence, 49 + 26 = 75

i) To find the number in the blank space, subtract 40 from 76 as:

76 – 40 = 36

Hence, 40 + 36 = 76

j) To find the number in the blank space, subtract 50 from 98.

98 – 50 = 48

Hence, 98 = 48 + 50

k) To find the number in the blank space, add 35 and 21 as:

35 + 21 = 35 + 20 + 1

= 55 + 1

= 56

Hence, 56 – 21 = 35

l) To find the number in the blank space,subtract 20 from 57.

57 – 20 = 37

Hence, 57 – 20 = 34

c) 55 + 25 =____

d) 19 + 61 = ____

e) _____ = 34 + 63

f) 67 + 25 = _____

g) _____ = 48 + 42

h) _____ = 53 + 64

i) 72 + 56 = _____

Ans. Do it mentally. Following are the steps for mental calculations.

a) 33 + 42 = 30 + 3 + 40 + 2

= 70 + 3 + 2

= 75

b) 33 + 27 = 30 +3 + 20 + 7

= 50 + 3 + 7

= 60

c) 55 + 25 = 50 + 5 + 20 + 5

= 70 + 5 + 5

= 80

d) 19 + 61 = 10 + 9 + 60 + 1

= 70 + 9 + 1

= 80

e) 34 + 63 = 30 + 4 + 60 + 3

= 90 + 4 + 3 = 97

f) 67 + 25 = 60 + 7 + 20 + 5

= 80 + 7 + 5

= 92

g) 48 + 42 = 48 + 40 + 2

= 50 + 40

= 90

h) 53 + 64 = 50 + 3 + 60 + 4

= 110 + 3 + 4

= 117

i) 72 + 56 = 70 + 2 + 50 + 6

= 120 + 2 + 6

= 128

Q11. A teacher kept a record of the fruits students like. This is what she found:

Find out:

(a) How many students in the school like oranges?

(b) How many students in the school like mangoes?

(c) Altogether, how many students are there in the school?

(d) Is the number of girls more than 350 or less than 350?

Ans.

(a) There are 136 girls and 128 boys in the school who like oranges. To find the total number of students who like oranges, add 136 and 128.

136 + 128 = 264

Therefore, 264 students in the school who like oranges.

(b) There are 240 girls and 243 boys in the school who like mangoes. To find the total number of students who like mangoes, add 240 and 243.

240 + 243 = 483

Therefore, 483 students in theschool like mangoes.

(c) Step1: Among the girls 136 like oranges and 240 like mangoes. To find the total number of girls add 136 and 240.

136 + 240 = 376

There, are 376 girls in the school.

Step 2: Since 128 boys like oranges and 243 like mangoes, to find the total number of boys add 128 and 243.

128 + 243 = 371

Step 3: To find the total number of students, add the total number of boys and the total number of girls.

376 + 371 = 747

Therefore, there are 747 students in the school.

(d) There are 376 girls in the school. Since 376 is more than 350, the number of girls in the school is more than 350.

Hence, they found 182 pebbles in all.
