A tradesman marks his goods at 25% above the cost price and allows purchasers a discount of $$\frac{{25}}{2}$$%, his profit is: a) 8%
b) 8.5%
c) 8.625%
d) 9.375%

Answer: d
Explanation:

Let C.P = Rs. 100
Marked Price(M.P) = 100 + 25% of 100 = 125
Now, discount = $$\frac{{25}}{2}$$% on M.P
So, S.P = 125 – $$\frac{{25}}{2}$$% of 125 = Rs. 109.375
%Gain = 9.375%
