Question

A person spent ₹564 in buying pens and pencils. If cost of pen is ₹7 and pencil is ₹3 and if total number of things bought was 108 then how many of each type did he buy?

Answer 1

Answer:

Step-by-step explanation:

Let the number of pens be x.

number of pencils=108-x

cost of pens=7x

cost of pencils=3(108-x)

7x+3(108-x)=564

7x+324-3x=564

4x+324=564

4x=564-324

4x=240x=240/4

x=60

Number of pens=60

Number of pencils=108-60=48
