D. 18%

Answer: Option C

Solution(By Examveda Team)

Marked price of machine = Rs. 6800
After 1st discount
$$\eqalign{ & = \frac{{90}}{{100}} \times 6800 \cr & = {\text{Rs}}{\text{. 6120}} \cr} $$
Selling price of machine = Rs. 5202
$$\eqalign{ & {\text{Discount }}\% \cr & = \frac{{6120 - 5202}}{{6120}} \times 100 \cr & = \frac{{918}}{{6120}} \times 100 \cr & = 15\% \cr} $$
