Q:

A salesman calculated his profit on the marked price and finds it to be 30%. He forgets the fact that he gave a discount of 20%. What is his actual profit percentage?

A) 260/11%	B) 18.4%
C) 22.5%	D) 100/7%

Answer & Explanation Answer: D) 100/7%

Explanation:

When profit is calculated on Marked Price (M.P) then,

C.P = M.P - P%

Let M.P = 100

=> C.P = 100 - 30 = 70

But S.P = Rs. 80 as he gave 20% discount,

Now, Actual Profit = $\frac{80 - 70}{70} x 100$

= 100/7 %
