Given :

  • The sum of two numbers which are in the ratio 5:7 is 120.

To find :

  • The numbers =?

Step-by-step explanation :

Let, the first number be 5x.

Then, the second number be, 7x.

It is Given that,

The sum of both numbers = 120.

According to the question,

5x + 7x = 120

12x = 120

x = 120/12

x = 10.

Therefore, We got the value of, x = 10.

Hence,

The first number, 5x = 5 × x = 50.

Then, the second number, 7x = 7 × 10 = 70.

Therefore, the numbers are 50 and 70 respectively.

Thus, Option c. 50, 70 is the correct option.
