Question

A book bought for ₹80 and sold it for ₹100. Find his gain %.

Answer 1

Answer:

Given,

C.P = Rs. 80

S.P = Rs. 100

Now,

profit = S.P - C.P = 100 - 80 = 20 Rs.

profit % = profit/C.P × 100

so, profit % = 20/80 × 100 = 1/4 × 100 = 25 %

Hence, the gain percentage is 25 %.

Answer 2

Answer:

C.p of anbook =80

S.p of an book =100

Gain%=s.p-c.p/c.p ×100%

=100-80/80 ×100%

=25%
