============================
Let us assume the Age of C as X years.
Then Age Of B = 2X years .
Also , age of A = 2X + 2
Now,According to the given question ;
Total of their ages = 27
Putting in equation :
X + 2X + 2X + 2 = 27
5X + 2 = 27
5X = 25
X = 5
◼Age Of C = 5 years .
◼Age Of B = (5×2) = 10 years .
◼Age of A = (2×5 + 2 ). = 12 years .
----------------------------------------------------------------------------------------------------
Hence the Age of B = 10 years
◻◼Option (d) is correct

A = 2 + B
B= 2C
A + B +C = 27
2+ 2C +2C + c = 27
5c = 27 -2
5c = 25
c = 5
Hence B= 2C = 2 x 5 = 10 years
