Question

A boy buys 9 apples for ₹9.60 and sells them at 11 for ₹12. Find his gain or loss percent.​

Answer 1

Step-by-step explanation:

C.P. of 1 apple =Rs.99.60=Rs.1.06

S.P. of 11 apples=Rs.12

∴ S.P. of 1 apple=Rs.1112

=Rs.1.09

∴ C.P. of 11 apples=Rs.1.06×11

C.P.=Rs.11.66

S.P. of 11 apples=Rs.12

∴gain=S.P.−C.P.

Gain =12−11.66

Gain =0.34

Gain%=C.P.Gain×100

=11.660.34×100

Gain%=2.91%.
