Question

If 20 metres of a cloth costs ₹ 160, then how many metres of cloth can be bought for ₹ 90.

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

Answer 1

The correct option is D

11.25 m

Let the length of the cloth be $xm$

The length of the cloth and its cost will vary directly.

$\frac{160}{90}=\frac{20}{x}$

$x=\frac{90\times 20}{160}=11.25m$
