Question

6. Alisha is 9 years younger than Joanne. In 5 years’ time Joanne will be twice as old as Alisha. How old will Alisha be after 15 years?

Answer 1

Step-by-step explanation:

Let the age of Joanne be x years

Let the age of Alisha be x-9 years

A. T. Q

=> 2( x+5) = x+5

=> 2x+10 = x+5

=>2x+x = 10+5

=> 3x = 15

=> x = 15/3

=> x = 5

Therefore, after 15 years Alisha's age would be x+15 years

=> (5+15) years

=> 20 years Ans.
