Sally is 54 years old and her mother is 80, how many years ago was Sally's mother three times her age ? ​

Answer 1

Answer:

Let us assume x years back , Sally's mom's age is 3 times of Sally's age. Hence

3(54-x) = 80-x

162-3x=80-x

162-80 = 3x-x

82=2x

x=41.

So , 41 years ago, Mothers age is 3 times of Sally's age.

When Sally's age was 13 (54-41), and her mom age was 39 (80-41).
