Question

if selling price of an article is 4/3 of its cost price, the profit in the transaction.

Answer 1

Let the cost price be 300. Because the selling price is 4/3 times of its cost price, the selling price becomes (4/3)*300. This is nothing but 400.

The profit in the transaction is (400-300)/300=100/300 =1/3.

The profit percentage is (100/300)*100 i.e. 33.33%
