A father is twice as old as his son. 20 years ago the age of the father was 12 times the age of the son. The present age of the father is:
44 years
32 years
22 years
45 years
Explanation:
Let sons age = x. Then, fathers age = 2x.
12(x-20)=(2x-20)⇒⇒x=22
Fathers present age = 44 years
Let sons age = x. Then, fathers age = 2x.
12(x-20)=(2x-20)⇒⇒x=22
Fathers present age = 44 years
