Question

The cost price of 25 items is the same as the selling price of 20 items. Find the gain per cent.

A.

40%

B.

30%

C.

50%

D.

25%

Correct option is D


Given:
CP of 25 items = SP of 20 items
CP : SP = 20 : 25
CP : SP = 4 : 5
Solution:
As we know
Gain% = (SP – CP )/CP×100
Gain% = (5 – 4 )/4×100 = 25%
Therefore, the correct answer is (d).
