Question

Arun purchased $5$ pens for $₹75$ and Dinesh buys $7$ pens for $₹91$. Who bought pens cheaper?

Answer 1

Step 1: Calculate the cost per pen in Arun's case

The cost of $5$ pens $=₹75$

The cost of $1$ pen $=₹\frac{75}{5}$

$=₹15$

Step 2: Calculate the cost per pen in Dinesh's case

The cost of $7$ pens $=₹91$

The cost of $1$ pen $=₹\frac{91}{7}$

$=₹13$

Step 3: Find who bought pens cheaper

The cost per pen for Arun $=₹15$

The cost per pen for Dinesh $=₹13$

$15>13$

Hence, Dinesh bought pens cheaper than Arun.
