• solution: Age of B is 7years 10 months (94 months )
  
  according to first statement
  age
  A =0 months
  B =1year 3 months = 12 + 3 =15 months
  
  by 2nd statement
  age
  C = 0 months
  A = 2years 1 month = 12+12+1 = 25 months
  if age of A is 25 months then age of B becomes 15 +25 = 40 months because B is 15 months older than A.
  
  by 3rd statement
  age
  C = 4years 6months = 54 months
  then age of A becomes 25 + 54 = 79 months
  then age of B becomes 40 + 54 = 94 months
  
  hence answer is Age of B is 7years 10 months (94 months ) when C is 4years and 6months old.

• At the time of A's born B was 1yr 3 months old.
  At the time of C's born A was 2yr 1 month old. then b's age is 3 yr 4 months
  so B's age is 7 yr 10 months old when C's age is 4 yr 10 months old

• when a was born B was 15 months
  i.e. B-A=15
  When c was born A was 25 months
  i.e.A-C=25
  given that when C IS 54 months then B?
  FROM THE ABOVE EQUATION
  B-C=40
  C=54
  THEN
  B=94 months
  i.e. 7 year 10 months

• B-A=15 MONTHS------>(1)
  A-C=25 MONTHS------>(2)
  
  (1)+(2)===> B-C=40 MONTHS.
  
  IF C=4 YEARS 6 MONTHS.
  THEN B=40+56=96 MONTHS.
  
  SO, 96/12=7.833 YEARS

• C - 4Y 6M THEN
  C BORN WHEN A - 2Y 1M
  NOW C - 4Y 6M
  THEN A - 6Y 7M
  B - 1Y 3M WHEN A BORN
  
  NOW A - 6Y 7M
  THEN B - 8 YEARS OLD...

• Ans : 7 yrs 10 months old
  B was 15 Months (1 yr 3 months)
  A was 25 Months (2 yr 1 month)
  C was 54 Months (4 yr 6 months)
  
  15+25+54 =94
  94/12 (months per year)
  Age = 7 yrs 10 months

• 7 years and 10 months is the answer.
• 9 years agoHelpfull: Yes(0) No(0)
• C < A < B
  0 < 25(A is greater than C 2 yr 1 month ) < 40(B is greater than 1 yr 3 months)
  After 4 yrs 6 months ...
  C = 54 months
  
  A = 69 months -> C + A = 54 + 25 = 69
  B = 94 months -> C + A + B = 54 +25 + 15 = 94
  i.e. B age is : 7yrs 10 months
