1. Rahim is 12 years old. He is three times older than Karim. What will be the age of Rahim when he is two times older than Karim?
- A. 15 years
- B. 15 years
- C. 15 years
- D. 15 years
Answer: Option B
Explanation:
If karim's age is x , then Rahim's age will be 3x.
According to question, 3x = 12
or, x = 4
After y years, Rahim's age will be doubled than karim.
12 + y = 2(4 + y)
∴y = 4
At the time, Rahim's age = 3x + y = 3*4 + 4 = 16
ans: 16 yrs
