The mother's age is 3 times that of her son. After 8 years, the mother's age will be _____?

32 years

38 years

36 years

None of these

Let the son's current age be x.

The mother's current age is 3x (since it's 3 times the son's age).

After 8 years, the son's age will be x + 8.

After 8 years, the mother's age will be 3x + 8.

Now, let's assume the son's current age is 10 (x = 10). Then:

The mother's current age is 3x = 3(10) = 30.

After 8 years, the mother's age will be 30 + 8 = 38.
