Question

Two numbers are in the ratio 7 : 4 . If their difference is 18, then find the numbers.

Answer 1

42 and 24

Explanation:

The numbers in ratio 7 : 4 = 7x : 4x ( x is a multiplier ) , then

7x - 4x = 18 ( difference of 2 numbers is 18 )

3x = 18 ( divide both sides by 3 )

x = 6

Then

7x = 7 × 6 = 42

4x = 4 × 6 = 24

The numbers are 42 and 24

Answer 2

x = 24

. So, first number = 7 * 24 = 168. and second number = 4 * 24 = 96. Therefore the numbers are 168 and 96.
