Question

the cost of a pencil and a ball pen are in the ratio of 7:5
if their total cost is 60,find the cost of each​

Answer 1

Answer:

Step-by-step explanation:

Let their cost be x

cost of pencil= 7x

cost of ball pen= 5x

Total cost of both= 7x + 5x

= 12x

Now, 12x = 60 ( as per the question)

x= 5

cost of pencil= 7 ×5 = 35 rs

cost of pen= 5× 5 = 25 rs
