A is two years older than B who is twice as old as C. If the total of the ages of A, B and C be 27, then how old is B?
Answer: Option
Explanation:
Let C's age be x years. Then, B's age = 2x years. A's age = (2x + 2) years.
(2x + 2) + 2x + x = 27
5x = 25
x = 5.
Hence, B's age = 2x = 10 years.

@Sri
b is twice old as c means.. c=b/2
b=2c
b is twice old as c means.. c=b/2
b=2c

How come the age of A is 2X+2 years?

A+B+C=27
(B+2)+B+(B-2)=27
3B=27
B=9
(B+2)+B+(B-2)=27
3B=27
B=9
