Ans.1  a]2225808

b]2085892

0.2 Find the product using properties :

(a) 25x4x63

(b) 76x 2x 5

Ans2] a] 6300

b] 760

0.3 Find the product using suitable properties:

(a) 837x(100+3)

(b) 536x1002

Ans 3] 1. 837 × 100 + 837 × 3

83700 + 2511

862111

2.536 × (1000 + 2)

536 × 1000 + 536 × 2

536000 + 1072

537072

3.165 × (100 - 1) + 165

165 × 100 - 165 + 165

16500

Q.4 Find the value of:

(b) 0-89

(c) 6250+10

(d) 23+0

Ans 4] a] 5217

b] -89

c] 6260

d] 23

Q.5 Find the product of the largest 3 digit and 5 digit numbers using

Ans 5]  We know that the Largest five digit number = 99999

The largest three digit number = 999

According to the distributive property, a x (b - c) = (a x b) – (a x c)

Hence multiplying the largest five digit number and the largest three digit number becomes,  

99999 x 999 = 99999 x (1000-1)

Applying distributive property to the right hand side becomes,

=( 99999 x 1000)- (99999 x 1)

= 99999000 – 99999

99999 x 999 = 99899001.

Q.6 The predecessor of the smallest 3 digit number.

Ans 6] The smallest 3 digit number= 100

so the predessor of 100 = 99

0.7 A vendor supplies 67 litre of milk to a hotel in the morning and 33 litre of milk in the evening of the milk cost is rupees 37 per litre how much money is due to the vendor for per day.

Ans 7. Amount of milk supplied in the morning = 67

Amount of milk supplied is the evening = 33

Cost of milk per litre = Rs 37

Total cost per day = 37 × (67 + 33 )

= 37x100

=3700

Q.8 How many whole numbers are between 32 and 53 ?

Ans 8. 53−32−1=20

There are 20 whole numbers between 32 and 53.

0.9 Write five pairs of numbers whose quotient is 4.

Ans 9. 1] 24 ÷ 4

2] 20 ÷ 5

3] 28÷7

4] 36÷9

5] 8÷4

0.10 Find the value of 783x999+783

Ans 10. 783×999 +783

=782217+783

=783000
