**Ex 2.2 Class 6 Maths Question
1.**

Find the sum by suitable rearrangement:(a) 837 + 208 + 363

(b) 1962 + 453 + 1538 + 647

**Solution:
**(a) 837 + 208 + 363 = (837 + 363) + 208

= 1200 + 208 [Using associative property]

= 1408

(b) 1962 + 453 + 1538 + 647

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

= 3500 + 1100 = 4600

Find the product by suitable rearrangement:(Ð°) 2 × 1768 × 50

(b) 4 × 166 × 25

(c) 8 × 291 × 125

(d) 625 × 279 × 16

(e) 285 × 5 × 60

(f) 125 × 40 × 8 × 25

**Solution:****
**(a) 2 × 1768 × 50 = (2 × 50) × 1768 = (100) × 1768 = 176800

(b) 4 × 166 × 25 = 166 × (25 × 4) = 166 × 100 = 16600

(c) 8 × 291 × 125 = (8 × 125) × 291 = 1000 × 291 = 291000

(d) 625 × 279 × 16 = (625 × 16) × 279 = 10000 × 279 = 2790000

(e) 285 × 5 × 60 = 285 × (5 × 60) = 285 × 300 = (300 – 15) × 300 = 300 × 300 – 15 × 300 = 90000 – 4500 = 85500

(f) 125 × 40 × 8 × 25 = (125 × 8) × (40 × 25) = 1000 × 1000 = 1000000

3.**

Find the value of the following:(Ð°) 297 × 17 + 297 × 3

(b) 54279 × 92 + 8 × 54279

(c) 81265 × 169 – 81265 × 69

(d) 3845 × 5 × 782 + 769 × 25 × 218

**Solution:****
**(a) 297 × 17 × 297 × 3 = 297 × (17
+ 3)

= 297 × 20 = 297 × 2 × 10

= 594 × 10 = 5940

(b) 54279 × 92
+ 8 × 54279 = 54279 × (92 + 8)

= 54279 × 100 = 5427900

(c) 81265 ×
169 – 81265 × 69

= 81265 × (169 – 69)

= 81265 × 100 = 8126500

(d) 3845 × 5 × 782 + 769 ×
25 × 218 = 3845 × 5 × 782 + 769 × 5 × 5 × 218

= 3845 × 5 ×
782 + (769 × 5) × 5 × 218

= 3845 × 5 ×
782 + 3845 × 5 × 218

= 3845 × 5 ×
(782 + 218)

= 3845 × 5 ×

4.**

Find the product using suitable properties.(a) 738 × 103

(b) 854 × 102

(c) 258 × 1008

(d) 1005 × 168

**Solution:
**(a) 738 × 103
= 738 × (100 + 3)

= 738 × 100 + 738 × 3 [Using distributive property]

= 73800 + 2214 = 76014

(b) 854 × 102
= 854 × (100 + 2)

= 854 × 100 + 854 × 2 [Using
distributive property]

= 85400 + 1708 = 87108

(c) 258 × 1008
= 258 × (1000 + 8)

= 258 × 1000 + 258 × 8
[Using distributive property]

= 258000 + 2064 = 260064

(d) 1005 × 168
= (1000 + 5) × 168

= 1000 × 168 + 5 × 168 [Using
distributive property]

= 168000 + 840 = 168840

5.**

A taxidriver 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 cost ₹44 per litre, how much did he spend in all on
petrol?**Solution:
**Petrol filled on Monday = 40 litres

Cost of petrol = ₹44 per litre

Petrol filled on Tuesday = 50 litres

Cost of petrol = ₹44 pet litre

∴ Total money spent in all

= ₹(40 × 44 + 50 × 44)

= ₹(40 + 50) × 44 = ₹90 × 44 = ₹3960

6.**

A vendor supplies 32 litres of milk to a hotel in
the morning and 68 litres of milk in the evening. If the milk costs ₹15 per
litre, how much money is due to the vendor per day?**Solution:
**Milk supplied in the morning = 32 litres

Cost of milk = ₹15 per litre

Milk supplied in the evening = 68 litres

Cost of milk = ₹15 per litre

Money due to the vendor per day = ₹(32 × 15 + 68 ×
15)

= ₹(32 + 68) ×
15 = ₹ 100 × 15 = ₹ 1500
