Answer:

Rohan's present age is 7 years.

Step-by-step explanation:

Let Rohan's age be x years.

Then his mother's age is, (x + 26) years.

It is provided that: (x+3)(x+29)=360

Solve this equation for x as follows:

(x+3)(x+29)=360\\x^{2}+29x+3x+87=360\\x^{2}+32x-273=0\\x^{2}+39x-7x-273=0\\x(x+39)-7(x+39)=0\\(x-7)(x+39)=0

If (x - 7) = 0, the the value of x is 7.

If (x + 39) = 0, the the value of x is -39.

Since age cannot be negative, Rohan's age is 7 years.

Then his mother's age is, x+26=7+26=33 years.

Thus, Rohan's age is 7 years.
