Question

A shopkeeper gains rs.1 on each pen and loses 40 paise on each pencil. He sells 45 pens and some pencils losing rs. 5 in all. How many pencils does he sells

Answer 1

If shopkeeper sell 125 pencils then he loses 125×40=5000 paise i.e Rs.50 and 45 pens gave him profit of Rs.45
then 50-45=5 rs he loses in all.
Therefore total no.of pencils sold by him is 125.
Let A=total pencil sold
40×A-4500=5000
40×A=5000
A=125

Answer 2

hey friend

No. of pen sells=45
.
therefore profit = 45×1=45rs.

loss on x pencil = x ×.40=0.40x rs.

a/q. =

=>0.40x-45rs=5

=>0.40x = 50rs

=>x=50/0.40

=>x=125______answer
