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?
7
8
9
10
11
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.

Can you give me short cut to solve this?

Sri said:   1 decade ago
B is twice as old as C means C=2B right?

Priya said:   1 decade ago
How come the age of A is 2X+2 years?

Renu said:   1 decade ago
A+B+C=27
(B+2)+B+(B-2)=27
3B=27
B=9
