Question

Gabrielle's age is two times Mikhail's age. The sum of their ages is 27. What is Mikhail's age?

Answer 1

Gabrielle is 18 and Mikhail is 9

Answer 2

Let Gabrielle's age be = x years

Let Mikhail's age be = y years

As given, Gabrielle's age is two times Mikhail's age

`x=2y`

The sum of their ages is 27

`x+y=27`

Putting x=2y, we have,

`2y+y=27`

`3y=27`

y=9

As x+y=27, x=18

Hence, Gabrielle's age is 18 years

Mikhail's age is 9 years.
