1. 12 year old Manick is three times as old as his brother Rahul. How old will Manick be when he is twice as old as Rahul?
- A. 14 years
- B. 14 years
- C. 14 years
- D. 14 years
Answer: Option B
Explanation:
Manick এর বর্তমান বয়স = 12; Rahul = 123123 = 4
ধরি, Manick x বছরে পরে হবে Rahul এর twice old.
তাহলে 12 + x = 2(4 + x)
x = 4
তাহলে Manick এর required age = 12 + 4 = 16 years.
