1. A father is three times as old as his son. After fifteen years the father will be twice as old as his son's age at that time. Hence the father's present age is--
- A. 36
- B. 36
- C. 36
- D. 36
Answer: Option C
Explanation:
Present age of father = 3x
Present age of son = x
After fifteen years there ages will be 3x + 15 and x + 15
By the given condition
3x + 15 = 2(x + 15)
3x + 15 = 2x + 30
X = 15
Therefore present age of father = 3x = 3×15 = 45 years (ans)
