Question

A is 3 years younger to his sister . If the sum of their ages is 27 years, what are their present ages?

Answer 1

Answer:

Sister's present age is 15 years

and A's age present age is 12 years

Step-by-step explanation:

Assuming his sister's present age is '' x ''

now A is 3 years younger to his sister.

therefore A's age will be = ( x - 3 ) years

Also it is mentioned in the question that sum of their ages is 27 years.

So we can write

x + ( x - 3 ) = 27

or 2x - 3 = 27

or 2x = 27 + 3

or 2x = 30

or x = 15 years

So sister's present age is 15 years

and A's age present age is ( 15 - 3 ) = 12 years
