Question

3. A girl is 12 years older than her daughter. 4 years ago when she gave birth to her daughter while in SHS 1, she was 4 times as old as her daughter. How old are they now?​

Answer 1

The mother is now 20 years old and the daughter is 8 years old. Let the mother's age be x and the daughter's age be y. We can write the equation x - 12 = y and x - 4 = 4y. Solving these equations simultaneously gives us x = 20 and y = 8.
