Choose the correct option.

If on an item a company gives 25% discount, they earn 25% profit. If they now give 10% discount then what is the profit percentage.

A40%

B55%

C35%

D30%

Explanation:

Lets assume the cost = Rs x.
After giving 25% discount it becomes 0.75x
Selling price = 0.75x which gives 25% profit...(1)

Thus, after giving 10% discount it becomes 0.90x
Selling price = 0.90x ......(ii)
From eq. (1) and (2),
0.90x will gives = (25 * 0.90x)/ (0.75x) = 30 % profit.
