Answer 2

Answer:

The correct option is C.

Step-by-step explanation:

Mohsin is now three times the age of Mubeen.

$\text{Age of Mohsin}=3\times \text{Age of Mubeen}$

After 4 years the  age of Mohsin is

$\text{Age of Mohsin}+4=3\times \text{Age of Mubeen}+4$

It is given that after 4 years Mohsin’s age is x.

$x=3\times \text{Age of Mubeen}+4$

$x-4=3\times \text{Age of Mubeen}$

Divide both sides by 3.

$\frac{x-4}{3}=\text{Age of Mubeen}$

Therefore option C is correct.
