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.
