Answer 1

Answer:

(i). Ahsan's Present Age = 16

(ii). Age of Ahsan's Mother when ahsan is 21 years old = 50

Step-by-step explanation:

Let's say, x represents the age of ahsan.

y represents the age of his mother.

The system of equation from the date given is:

$\begin{bmatrix}x+y=61\\ -x+y=29\end{bmatrix}$

Solve them will get us:

$x=16,\:y=45$
