Raju purchases 10 pens for Rs. 150 and Manish buys 7 pens for Rs. 84. Can you say who got the pens cheaper?
Given:
Raju purchases 10 pens for $Rs.\ 150$ and Manish buys 7 pens for $Rs.\ 84$.
To do:
We have to find the pens purchased by Raju or Manish are cheaper.
Solution:
The pens purchased by Raju for $Rs.\ 150 = 10\ pens$
Therefore,
The cost of $1\ pen = \frac{150}{10}$
$=Rs.\ 15$
The cost of $1\ pen$ purchased by Raju is $Rs.\ 15$.
The pens purchased by Manish for $Rs.\ 84 = 7\ pens$
Therefore,
The cost of $1\ pen = \frac{84}{7}$
$=Rs.\ 12$
The cost of $1\ pen$ purchased by Manish is $Rs.\ 12$.
The pens purchased by Manish are cheaper than the pens purchased by Raju.
