Given:

If thrice of A's age 6 years ago be subtracted from years ago be subtracted from twice his present age, the result would be equal to his present age.

To find:

The present age of A's.

Explanation:

Let the present age A's be R years.

• 6 years ago:

The age of A's= (R-6) years.

According to the question:

→ R= 2R - 3(R-6)

→ R= 2R - 3R+ 18

→ R= -R +18

→ R + R= 18

→ 2R = 18

→ R= $\cancel{\frac{18}{2} }$

→ R= 9 years.

Thus,

The present age of A's is 9 years.
