The sum of two numbers is 39. one number is 2 times as large as the other. What are the numbers?

Solution:

Let one of the numbers be ‘x’ and the other ‘y’.

Given that:

the sum of two numbers is 39 and one number is 2 times as large as the other.

⇒ x + y = 39 ……(1) and

y = 2x

Substituting the value of y in equation (1),

x + 2x = 39

3x = 39

x = 13

∴ y = 2 × 13

= 26

Hence the required numbers are 13 and 26.

The sum of two numbers is 39. one number is 2 times as large as the other. What are the numbers?

Summary:

For the sum of two numbers being 39 where one number is 2 times as large as the other, the numbers are 13 and 26.
