============================

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

Answer 2

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
