Question

at what rate percent the cost price must be increased to fix the selling price of an article to make 20% profit after allowing 10% discount on the costumer? ( step by step explanation)​

Answer 1

Answer:

30%

Step-by-step explanation

Let's take 300 for example.

10 % discount on 300 is 300- 10% of 300 = 300- 30 = 270.

20% profit = 360 using the same formula.

If we want 20% profit even after 10% discount, we need profit of 360-270= 90.

90 is 30% of 300.

Answer is 30%.
