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

Answer:

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

Step-by-step 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

$x-25+6=\frac{x+6}{2}$

Solve for x

$x-19=\frac{x+6}{2}$

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
