Question

gmat janet is now 25 years younger than her mother Carol. If in 6 years Janet's age will be half Carol’s age, how old was Janet 5 years ago?

Answer 1

Janet age 5 years ago is 19-5= 14 years

Explanation:

janet is now 25 years younger than her mother Carol.

Let x be the age of mother

Janet is x-25

In 6 years, Carol becomes x+6

`x-25+6=(x+6)/(2)`

Solve for x

`x-19=(x+6)/(2)`

multiply both sides by 2

`2x-38=x+6`

subtract x on both sides

`x-38=+6`

add 38 on both sides

x=44

Age of Carol now = 44

Age of Janet now = 44-25=19 years

Janet age 5 years ago is 19-5= 14 years
