Question

two numbers are in ratio 7:4 if their difference is 72 find the numbers

Answer 1

Hey!

Let one number be 4x

Another be 7x

7x-4x = 72

3x = 72

x = 72/3

x = 24

One number 24*7 = 168
Another number 24*4 = 96

Answer 2

Let the common ratio be x.

Let 7x be the first number.

Let 4x be the second number.

Given that the difference of two numbers = 72.

7x - 4x = 72

3x = 72

x = 72/3

x = 24.


So, first number = 7 * 24 = 168.

and second number = 4 * 24 = 96.

Therefore the numbers are 168 and 96.


Verification:

7x - 4x = 72

7(24) - 4(24) = 72

168 - 96 = 72

72 = 72.


Hope this helps!
