Question

Himanshu purchased 7 pens for Rs. 91 and shubham bought 9 pens of the same quality for Rs. 108. Who bought the pens at a cheaper rate?

Answer 1

hey..

Himanshu => 7x = 91
x = 91/7
x = 13

Subham => 9x = 108
x = 108/9
x = 12

subham bought the pens at cheaper rate

Answer 2

by himanshu
pens = 7
total = 91
cost of one pen = total/ number of pens
= 91/7
= 13
so the cost of one pen here is 13

by shubam
pens = 9
total = 108
cost of one pen = total/ number of pens
= 108/9
= 12
so the cost of pen here is 12

which means tgat shubam had gat a cheaper rate (intelligent boy).

hope it helps you...
