1. 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 ?

A. $22 \frac{1}{3} %$

B. 25%

C. $33 \frac{1}{3} %$

D. $37 \frac{17}{24} %$

Solution:

Market price of dining table = Rs. 3000
After discount, cost price

\begin{aligned} =  3000 \times \frac{90}{100} \times \frac{85}{100} \\ =  Rs . 2295 \end{aligned}

After transport charges = 2295 + 105

\begin{aligned} Cost price  =  Rs . 2400 \\ Selling price  =  Rs . 3200 \\ Profit % \\ = \frac{3200 - 2400}{2400} \times 100 \\ = \frac{800 \times 100}{2400} \\ = 33 \frac{1}{3} % \end{aligned}
