Question

Raju purchases $10$ pens for $₹150$ and Manish buys $7$ pens for $₹84$. Can you say who got the pens cheaper?

Answer 1

Here

To find who got the cheaper pen, we have to find the amount paid for $1$ pen by both.

Amount paid for $10$ pens by Raju $=₹150$

$\Rightarrow$Amount paid for $1$ pen by Raju $=\frac{150}{10}=₹15$

Amount paid for $7$ pens by Manish $=₹84$

$\Rightarrow$Amount paid for $1$ pen by Manish $=\frac{84}{7}=₹12$

As $₹12<₹15$

Hence Manish got the pen cheaper.
