Answer 2

Answer:

Hakimi will be 12 years old when he is twice as old as his sister.

Explanation:

Let us consider the sister's age to be x

Hakimi is four times as old as his sister

∴ Hakimi's age = 4x = 8

∴ Sister's age = x = 8/4 = 2

Thus, Hakimi is 6 years older than his sister.

6*2 = 12

Therefore, Hakimi will be 12 years old when he is twice as old as his sister.
