Let, Fahim's age be x year

Shakib is 2x years old.

4 years ago Fahim was (x-4) years old and 4 years ago Shakib was (2x-4) years old

According to question

$3 (x - 4) - 6 = 2 x - 4 \Rightarrow 3 x - 12 - 6 = 2 x - 4 \Rightarrow 3 x - 18 = 2 x - 4 \Rightarrow 3 x - 2 x = 18 - 4 = 14 ∴ x = 14$

After 2 years, Fahim will be = 14+2 = 16 years old

And Shakib will be = $2 \times 14) + 2 = 28 + 2 = 30$ years old
