Q:
A) 18 | B) 25 |
C) 7 | D) 15 |
Answer: A) 18
Explanation:
Explanation:
Given Karthik’s age = 32 years
Karthik’s son age = 7 years
Difference between their ages = K - S = 32 - 7 = 25 years ….(1)
Now, required K = 2S ……(2)
Put (2) in (1)
2S - S = 25
=> S = 25 years
Hence, at the age of 25 years of Karthik’s son, Karthik will be twice as his son’s age.
25 - 7 = 18 years
Therefore, after 18 years the father be twice as old as the son.
