Answer 2

Answer:

The numbers are 110 and 70.

Given:

Two numbers are in the ratio 11:7 and their sum is 180.

To find:

What are the numbers?

Solution:

Let the one number be 11x.

and the other be 7x.

Sum of the numbers = 180

=> 11x+7x = 180

=> 18x = 180

=> x = 180/18

=> x = 10

Hence, one number = 11x = 11×10 = 110.

And the other number = 7x = 7×10 = 70.

Verification:

Sum of the numbers = 180

=> 110+70 = 180

=> 180 = 180

Here, LHS = RHS.

Hence, verified.
