Question

The cost of a pen and a notebook is 60 if the cost of a pen is 10 less than the cost of the notebook. Find their cost

Answer 1

Let the cost of a notebook be x
Cost of a pen = x-10
Given, cost of both pen and book= 60
then, x+(x-10) = 60
x = 35
therefore cost of the notebook = x = 35
Cost of pen = x- 10 = 35-10= 25
