Jasper is twice as old as Simon now. Simon was 1/5 as old as Jasper in 12 years ago. How old is Jasper in 12 years's time?

44 years old

Step-by-step explanation:

Let the age of Jasper be j years old now.

Now:

Jasper➣ j

Simon ➣ j/2

12 years ago:

Jasper➣ j -12

Simon➣ j/2 -12

Given that Simon's age=⅕(Jasper's age),

j/2 -12= ⅕(j -12)

Multiply by 5 on both sides,

2.5j -60= j -12

2.5j -j= 60 -12

Simplify:

1.5j= 48

÷1.5 on both sides:

j= 48 ÷1.5

Simplify:

j= 32

12 years time:

Jasper➣ j +12

Thus, Jasper's age

= 32 +12

= 44
