Question

A fruit seller bought 2dozen bananas at ₹20 a dozen amd sold them at ₹3 per banana. Find his gain or loss.

Answer 1

2 dozen = 12 banana for Rs. 20.

Now he sold each for Rs. 3.

So total SP= 12*3 = 36

As SP>CP,

so he gained 36-20 = Rs.16

Answer 2

CP of 1 dozen banana = 20
CP of 2 dozen banana = 20 *2 = 40
SP = 24*3=72
SP>CP
Gain = 72-40=32
G%=32÷40×100
=80%
