Answer 2

Given:

• The ratio of two numbers is 11:9
• Sum of two numbers = 180

To find:

• The numbers?

Solution:

☯ Let the two numbers be 11x and 9x.

According to the given Question:

First number + Second number = 180

⇒ 11x + 9x = 180

⇒ 20x = 180

⇒ x = 180/20

⇒ x = 9

Therefore,

• First number, 11x = 11 × 9 = 99
• Second number, 9x = 9 × 9 = 81

Hence, the required two numbers are 99 and 81 respectively.

Verification:

It is given that,

Sum of required two numbers = 180

Therefore,

→ 99 + 81 = 180

→ 180 = 180

→ LHS = RHS

Hence, Proved!
