Answer & Solution
Correct Answer:
Option
D
Let the cost price of goods = Rs. 100
Mark price of goods = Rs. 130 (30% discount)
Selling price of goods = 90% of 130 = Rs. 117
Gain = 117 - 100 = Rs. 17
$${\text{Gain}}\% = \frac{{17}}{{100}} \times 100 = 17\% $$
Mark price of goods = Rs. 130 (30% discount)
Selling price of goods = 90% of 130 = Rs. 117
Gain = 117 - 100 = Rs. 17
$${\text{Gain}}\% = \frac{{17}}{{100}} \times 100 = 17\% $$
