Question

Mr Moron calculates his profit percentage as a
percentage of selling price. He sells an item for Rs.
150 and calculates his profit percentage to be 20%.
What is the true profit percentage?​

Answer 1

Answer:

20%=1/5

Let sp=5

Then

Cp=5-1=4

Here

5=150(given)

1=150/5=30

So

Cp=4×30=120

Real profit=150-120=30

Profit%=30/120×100=25%
