Question

A shopkeeper purchased bananas at rupee 18 per dozen and sold 10 bananas at the rate of rupee 18 find the gain or loss percent

Answer 1

CP of one dozen bananas(12 bananas) =18
CP of one bananas = 18/12= 1.5

SP of 10 bananas=18
SP of one bananas=18/10=1.8

So, here we can see that SP is greater than CP
so, he get profit.

Profit=SP-CP
=1.8-1.5
=0.3
profit%= profit/CP ×100

$\frac{0.3}{1.5} \times 100$
