Question

A man bought eggs at ₹30 per 10 and sold at a rate of ₹46.80 per dozen. Find his gain or loss percent per egg.

Answer 1

hi
cost of 10 egg = 30
cost of 1 egg = 30/10
= 3

sp of 12 egg = 46.80
sp of 1 egg = 46.80/12= 3.9

now
the sp of 1 egg is more than the cp of one egg
that is 3.9 is greater than 3.00

when sp is greater than CP then that is a profit or gain
so gain = 3.9-3.0=0.9

gain percent = gain/CP × 100
= 0.9/3 ×
=30 percent
