Question

A person spent 564 rupees in buying pens and pencils if cost of each pen is 7 rupees and pencils 3 rupees and if total no of things brought was 108 how many of each type did he buy ?

Answer 1

Step-by-step explanation:

let the no of pen be x

no of pencil be 108 - x

a.t.q.

7*x + 3(108 - x)= 564

7x + 324 - 3x = 564

4x = 564-324

4x = 240

X = 240/4

X = 60

No.of pens = 60

pencils = 108-60

= 48
