Question

If 20 metres of a cloth costs ₹ 160 then how many metres can be bought for ₹ 80?

• A. 12 m
• B. 13 m
• C. 12. 56 m
• D. 11.25 m

Answer 1

The correct option is D

11.25 m

Given, the cost of 20 metres of cloth = ₹ 160

The length of cloth can be bought for ₹ 1= $\frac{20}{160}$

= $\frac{1}{8}$ m

$\therefore$ The length of cloth can be bought for ₹ 80 = 80 $\times$ The length of cloth for ₹ 1

= 80 $\times$ $\frac{1}{8}$

= 10 m
