Question

The marked price of a book is ₹ 200 which is offered at a discount of 20%. What is the ratio between the selling price and marked price of the book?

• A. 5 : 4
• B. 8 : 9
• C. 4 : 5
• D. 9 : 8

Answer 1

The correct option is C 4 : 5

Marked price = ₹200
Discount = 20%
Selling price = Marked price - (20% of Marked price)
$\Rightarrow S.P=200-(\frac{20}{100}\times 200)$
$\Rightarrow S.P=200-40$
$\Rightarrow S.P=₹160$

$\therefore \text{Ratio of S.P to M.P}=\frac{S.P}{M.P}=\frac{160}{200}=\frac{4}{5}$

$\Rightarrow S.P:M.P=4:5$
