Question

The ratio of two numbers is 7 to 5. The sum of the numbers is 24. What are the numbers?

12 and 12

 

14 and 10

 

21 and 15

 

18 and 6

Answer 1

14 and 10

Explanation:

The ratio of the 2 numbers = 7x : 5x

The sum of the 2 numbers is 24, hence

7x + 5x = 24

12x = 24 ( divide both sides by 12 )

x = 2

7x = 7 × 2 = 14

5x = 5 × 2 = 10

Thus the numbers are 14 and 10
