Question

I am 21 years old my father is 3 times my age how old eill i be when my father is 40

Answer 1

This question makes no sense.

If you’re 21, that means your father is 63.

Your father was 40 years old 23 years ago, meaning you’d be 21 - 23 = -2 years old, which makes no sense.

Answer 2

Well the answer is 13.3 so 13 years old

Explanation:

(F,Y) = (63,21)

Y3=F so F/3=y

so

F= 40

Y=?

40/3=Y

40/3=13.3
