Answer:

  • The daughter's is 10 years old and the mother is 30 years old.

Given:

  • A mother is three TIMES as old as her daughter. SIX years ago, the mother's age was six tines that of her daughter.

Need To Find:

  • How old are they now? 

Explanation:

Let X represent the daughter's age.

Therefore:

  • 3x is the mother's age.

➠ 6(x - 6) = 3x - 6

➠ 6x - 6 = 3x - 6

➠ 3x = 30

x = 10

  • Hence, the daughter's is 10 years old and the mother is 30 years old.
