Question

A vendor bought oranges at Rs.36 per dozen and sold it at the rate
of Rs.40 per dozen.find the profit or loss percent.

Answer 1

Here CP of one dozen = ₹36

And SP = ₹40

Since SP > CP therefore it is a profit

Profit  = SP - CP

Profit = 40 - 36

         = ₹4

Profit% = (Profit ÷ CP) ×100

= (4 ÷ 36)×100

= 100/9% or $11\frac{1}{9}$%
