Question

A dealer marks his goods 20% above cost price, he
then allows some discount on it and makes a profit
of 8%, then what is the rate of discount?
​

Answer 1

Let C.P. of article = Rs. 100

∴ Marked price = Rs. 120

On profit of 8% , Its S.P. = Rs. 108

∴ Discount = Rs. (120 – 108) = Rs. 12

∴ If discount be y%, then,

$120 \times y \div 100 </em><em>=</em><em> 12$

$y \: is \: equal \: to \: 12 \times 100 \div 120 = 10\%$
