Question

A shopkeeper fixed the marked price of his television to make profit of 40%. Allowing 20% discount on the marked price the television was sold. What percentage of profit will he make?

Answer 1

Assume initial price=Rs1

Market price=1*(1+40%)

=Rs1.4

Discount price=1.4*(1-20%)

=Rs1.12

Profit=Discount price-initial price

Profit=1.12-1=Rs0.12

i.e.,Profit makes by him=12%

Answer 2

Given :

Profit by fixed the marked price = 40%

Discount % = 20%

To find : Percentage of profit he will make = ?

Solution :

Total profit % = Profit  on marked price - Discount - $\dfrac{Profit\times Discount}{100}$

So, it becomes :

Total profit% would be :

$40-20-\dfrac{40\times 20}{100}\\\\=20-8\\\\=12\%$

Hence, he will make 12% of profit.
