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.

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

B=94 months
i.e. 7 year 10 months

ravi palla  (9 years ago)

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

M.Ravikumar   (9 years ago)

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
