Question

A trader marked a book 36% above its cost price and then gave a discount of 10% on it. If the trader made a net profit of -238 after paying a tax of 15% on the gross profit, find the cost price (in c) of the watch. ​

Answer 1

Answer:

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

Then the marked price =50% of 100+100=150

S.P. =150−20% of 150 =150−30=120.

% profit =

100

(120−100)×100

=20%

Thus, the profit percent is 20%.
