Question

A trader buys goods at 7.5% less than the list price. He allows a discount of 10% on his goods. If he wants
to get a profit of 20%, at what percent above the list price should he mark the goods?​

Answer 1

Answer:

Step-by-step explanation:

consider a is the list price the trader purchased

we have the expenditure of the goods purchased by the trader is (100%-7.5%)a=92.5% x a

=> to get 20% profit the price should be 120% x 92.5% x a (1)

consider b is the list price the trader should mark

we have 90% x b is the list price after applying discount 10% (2)

Hence (1) =(2)

=> b=  $\frac{111}{90} a$

to sum up, the list price he should mark the goods is $\frac{111}{90} a$ with a is the list price when the trader purchased the goods
