(b) 1962 + 453 + 1538 + 647

Ans.

(a) 837 + 208 + 363 = (837 + 363) + 208

= 1200 + 208

= 1408

(b) 1962 + 453 + 1538 + 647

= (1962 + 1538) + (453 + 647)

= 3500 + 1100

= 4600

= 1768 × 100

= 176800

(b) 4 × 166 × 25 = 166 × (4 × 25)

= 166 × 100

= 16600

(c) 8 × 291 × 125 = 291 × (8 × 125)

= 291 × 1000 = 291000

(d) 625 × 279 × 16 = 279 × (625 × 16)

= 279 × 10000

= 2790000

(e) 285 × 5 × 60 = 285 × (5 × 60)

= 285 × 300

(c) 258 × 1008 (d) 1005 × 168

Ans.

(a) 738 × 103 = 738 × (100 + 3)

= (738 × 100) + (738 × 3)

[By the distributivity of multiplication over addition]

= 73800 + 2214

= 76014

(b) 854 × 102 = 854 × (100 + 2)

= (854 × 100) + (854 × 2)

[By the distributivity of multiplication over addition]

= 85400 + 1708

= 87,108

(c) 258 × 1008 = 258 × (1000 + 8)

= (258 × 1000) + (258 × 8)

[By the distributivity of multiplication over addition]

= 258000 + 2064

= 2,60,064

(d) 1005 × 168 = 168 × (1000 + 5)

= (168 × 1000) + (168 × 5)

[By the distributivity of multiplication over addition]

= 168000 + 840

= 1,68,840

Q.5 A taxi driver filled his car petrol tank with 40 litres of petrol on Monday. The next day, he filled the tank with 50 litres of petrol. If the petrol costs ₹44 per litre, how much did he spend in all on petrol?

Ans.

The cost of one litre petrol = ₹44
Petrol filled in tank on Monday = 40 litres

Petrol filled in tank on Tuesday = 50 litres

Driver spend money on petrol = 44 × (40+50)

= 44 × 90

= ₹3960

Thus, a taxi driver spent ₹3960 on petrol.

Q.6 Match the following:
(i) 425 × 136 = 425 × (6 + 30 +100) (a) Commutativity under multiplication.
(ii) 2 × 49 × 50 = 2 × 50 × 49 (b) Commutativity under addition.
(iii) 80 + 2005 + 20 = 80 + 20 + 2005 (c) Distributivity of multiplication over addition.

Ans.

The matched pairs are:

(i) → (c)

(ii) → (a)

(iii) → (b)
