A merchant marked cloth at Rs. 50 metre. He offers 2 successive discounts of 15% and 20%. The net price/metre is = ?

Answer: Option C

$$\begin{array}{rl}& 15\%=\frac{3}{20}\left(-\right)\\ & 20\%=\frac{1}{5}\left(-\right)\end{array}$$

Marked Price	:	Net Price
20	:	17
5	:	4
100	:	68

100 units = Rs. 50
1 unit = Rs. 0.50
68 units = Rs. 34
