Question

Bob buys 3 toys at ₹17 each. The total cost of the toys is ₹.

• A. 51
• B. 21
• C. 41
• D. 43

Answer 1

The correct option is A 51

Cost of 1 toy = ₹17

Cost of 3 toys = 3 x 17

We split 17 as 10 and 7 and multiply 3 by 10 and 7.

17 = 10 + 7

3 x 10 = 30
3 x 7 = 21

30 + 21 = 51

Thus, 3 x 17 = 3 x 10 + 3 x 7 = 51

Hence, the total cost of the toys is ₹51.
