Answer:
After 9 years mother's age will be 3 times more than kofi's age .
Step-by-step explanation:
Given
Age of Kofi = 8 years
Age of Mother = 42 years
According to question , 3 times more than kofi's age .
=> ( 8+ x ) 3 = 42 + x
=> 24 + 3x = 42 + x
=> 3x - x = 42 - 24
=> 2x = 18
=> x = 18/2
=> 9
After 9 years ,
- Age of Kofi = 8 + 9 = 17 years
- Age of Mother = 42 + 9 = 51 years
