- 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. - 10 years agoHelpfull: Yes(9) No(0)

- 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... - 10 years agoHelpfull: Yes(0) No(0)
- 4.6+3.4=8 years
- 10 years agoHelpfull: Yes(0) No(2)
- 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 - 10 years agoHelpfull: Yes(0) No(0)
- 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 - 9 years agoHelpfull: Yes(0) No(0)
- ans= 7 year 10 month.
- 8 years agoHelpfull: Yes(0) No(0)
- answer is 7 years and 10 months i.e. 94 months.
