Question

The difference of two number is 9 and they are in the ratio 4:7 Find the number?​

Answer 1

Answer:

21 and 12.

Step-by-step explanation:

Let's assume One of the number be x.

According to the problem, the other number is (x - 9).

Also, $\frac{x - 9}{x} = \frac{4}{7}$

=> 7x - 63 = 4x

=> 7x - 4x = 63

=> 3x = 63

∴ x = $\frac{63}{3} = 21$

∴ x - 9 = 21 - 9 = 12.
