Question

Ram went to a shop and purchased a pen for ₹15.60. He purchased another pen and paid ₹21.31to the shopkeeper. What is the price of the another pen?

• A. $₹4.71$
• B. $₹5.11$
• C. $₹5.61$
• D. $₹5.71$

Answer 1

The correct option is D $₹5.71$

At first we convert them into like fractions having the denominator as $100$.

$15.60=\frac{1560}{100}$ [The price of the first pen]

$21.31=\frac{2131}{100}$ [Total amount]

The price of the another pen = ₹21.31 - ₹15.60
$=\frac{2131}{100}-\frac{1560}{100}$

$=\frac{2131-1560}{100}$

$=\frac{571}{100}=₹5.71$
