Question

The sum of two numbers is 108. If their ratio is 5:7, then find those numbers.

Answer 1

Let one no. be 5x.

Then,

The second numbed will be 7 x .

ACCORDING TO THE QUESTION,

5x + 7x = 108
12 x = 108
X= 9

So,

❇ FIRST NUMBER = 5X = 45

❇ SECOND NUMBER = 7x = 63.

Answer 2

Solution :

Ratio two numbers = 5 : 7

Let first number = 5x ,

Second number = 7x

According to the problem given , we

get ,

5x + 7x = 108

=> 12x = 108

=> x = 108/12

=> x = 9

Therefore ,

Required Numbers are ,

First number = 5x = 5×9 = 45

Second number = 7x9 = 63
