Question

Apple are bought at 10 for 75 rupees and sold at 96 rupees per dozen find the gain or loss percent

Answer 1

C.P of 10 apples =Rs.75
C.P of 1 apple =Rs.75/10=Rs.7.5


S.P of 12 apples=Rs.96
S.P of 1 apple=Rs.96/12=Rs. 8

Here,S.P>C.P
Hence,there is gain of Rs.(8-7.5)=Rs.0.5

Gain%=(gain/C.P×100)%
=(0.5/8×100)%
=6.25%

Answer 2
