Answer & Solution
Correct Answer:
Option
A
Let the son's present age be x years. Then, (38 - x) = x
⇒ 2x = 38.
⇒ x = 19.
∴ Son's age 5 years back (19 - 5) = 14 years.
⇒ 2x = 38.
⇒ x = 19.
∴ Son's age 5 years back (19 - 5) = 14 years.

Logingonna tell me how we do...
XG cute and nice
we don't like to mess up twice
Son's age at time of birth say 0 and now it is x years old .
we can say that x(father's age at time of son's birth) + x(son's present age) = 38(father's present age)
x+x=38 => 2x=38 => x=19
5 years back: 19-5=14 years old
