= 3500 + 1100

= 4,600

**Q.2. Find the product by suitable rearrangement:**

**A. 2 x 1768 x 50**

**Ans.=** ( 2 x 50 ) x 1768

= 100 x 1768

= 1,76,800

**B. 4 x 166 x 25**

**Ans. =** ( 4 x 25 ) x 166

= 100 x 166

= 16,600

**C. 8 x 291 x 125**

**Ans. =** ( 8 x 125 ) x 291

= 1000 x 291

= 2,91,000

**D. 625 x 279 x 16**

**Ans.** = ( 625 × 16 ) × 279

= 10000 × 279

= 27,90,000

**E. 285 x 5 x 60**

**Ans.** = 285 x ( 5 x 60 )

= 285 x 300

= 85,500

**F. 125 x 40 x 8 x 25**

**Ans.** = ( 125 x 40 ) x ( 8 x 25 )

= 5000 x 200

= 10,00,000

**Q.3. Find the value of the following :**

**A. 297 x 17 + 297 x 3**

**Ans.** = 297 x ( 17 + 3 )

= 297 x 20

= 5,940

**B. 54279 x 92 + 8 x 54279**

**Ans.** = 54279 x ( 92 + 8 )

= 54279 x 100

= 54,27,900

**C. 81265 x 169 – 81265 x 69**

**Ans.** = 81265 ( 169 – 69 )

= 81265 x 100

= 81,26,500

**D. 3845 x 5 x 782 + 769 x 25 x 218**

**Ans.** = (3845 x 5 ) x 782 + ( 769 x 25 ) x 218

= 19225 x 782 + 19225 x 218

= 19225 x ( 782 +218 )

= 19225 x 1000

= 1,92,25,000

**Q.4. Find the product using suitable properties:**

**A. 738 x 103**

**Ans.** Using Distributivity over addition

= 738 x ( 100 + 3 )

= 738 x 100 + 738 x 3

= 73800 + 2214

= 76,014

**B. 854 x 102**

**Ans.** Using Distributivity over addition

= 854 x ( 100 + 2 )

= 854 x 100 + 854 x 2

= 85400 + 1708

= 87,108

**C. 258 x 1008**

**Ans.** Using Distributivity over addition

= 258 x ( 1000 + 8 )

= 258000 + 2064

= 2,60,064

**D. 1005 x 168**

**Ans.** Using Distributivity over addition

= ( 1000 + 5 ) x 168

= 1000 x 168 + 168 x 5

= 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 Rs.44 litre, how much did he spend in all on petrol?**

**Ans.** Total Money spend on petrol

= 40 x 44 + 50 x 44

= 44 x ( 40 + 50 )
