A father's age is one year more than 5 times of his son's age. After 3 years, the father's age would be 2 years less than four times the son's age. Find the present age of the father.
Answer & explanation
Correct answer: option 2
At present :
⇒ F = 5 S + 1 ..................(i)
After 3 years:
⇒ F + 3 = 4 (S + 3) - 2
⇒ F = 4 S + 12 - 5
⇒ 5 S + 1 = 4 S + 7 (from (i))
⇒ S = 6
⇒ Therefore, age of Father = 5 S + 1 = (5 × 6) + 1 = 31 years
