A purchased a dining table marked at Rs. 3000 at a successive discounts of 10% and 15% respectively. He gave Rs. 105 as trans-portion charge and sold it at Rs. 3200. What is his gain percentage ?

Solution(By Examveda Team)

Market price of dining table = Rs. 3000
After discount, cost price
$$\eqalign{ & {\text{ = 3000}} \times \frac{{90}}{{100}} \times \frac{{85}}{{100}} \cr & {\text{ = Rs}}{\text{. 2295}} \cr} $$
After transport charges = 2295 + 105
$$\eqalign{ & {\text{Cost price = Rs}}{\text{. 2400}} \cr & {\text{Selling price = Rs}}{\text{. 3200}} \cr & {\text{Profit }}\% {\text{ }} \cr & = \frac{{3200 - 2400}}{{2400}} \times 100 \cr & = \frac{{800 \times 100}}{{2400}} \cr & = 33\frac{1}{3}\% \cr} $$
