Answer & Solution
Correct Answer:
Option
D
Let the present ages of son and father be x and (60 -x) years respectively.
Then, (60 - x) - 6 = 5(x - 6)
⇒ 54 - x = 5x - 30
⇒ 6x = 84
⇒ x = 14
∴ Son's age after 6 years = (x + 6) = 20 years.
Then, (60 - x) - 6 = 5(x - 6)
⇒ 54 - x = 5x - 30
⇒ 6x = 84
⇒ x = 14
∴ Son's age after 6 years = (x + 6) = 20 years.

LoginF= 5x}
S= x} 6yrs ago
now f= 5x+6, s= x+6 => F+S = 60 = 6x + 12;
X = 12 (6 yrs ago),,, 18 (present),,,,24 (6yrs after)
=> 24 yrs is correct
