Question

A merchant wishes to makes a profit of 25% on his goods after allowing a discount of 10% for cash how much per cent above the cost price should he marked the price on his goods in his list​

Answer 1

Let the original C.P. be Rs. 100.

Then the marked price =25% of 100+100=125  

S.P. =125−10% of 125 =150−12.5 = 112.5.

$\text { Gain } \%=\frac{(112.5-100)}{100} \times 100=12.5 \%$

Percentage cost price should he marked the price on his goods in his list​ 12.5%
