Answer: b = 10 years
Step-by-step explanation:
a = b+2
b = 2c
so c = b/2
a+b+c = 27
b+2+b+b/2 = 27
2b+4+2b+b = 54
5b +4 = 54
5b = 50
b = 10

Let C's age be x years.
Then, B's age = 2x years and
A's age = (2x + 2) years
Given, 2x + 2 + 2x + x = 27
⇒ 5x + 2 = 27
⇒ 5x = 27 − 2 = 25
⇒ x = 5
∴ B's age = (2×5) years = 10 years.
