⭕️ age of C is x years
⭕️Age of B is 2x years
⭕️Age of A is (2x + 2) years
Now...
=2x+2+2x+x=27
⭕️simplifying...
=5x=27-2
=5x=25
⭕️Therefore
x=5
⭕️hence....
️ age of C is 5 years
️Age of B is 2 x= 10 years
️Age of A is (2x + 2)
=10+2
=12 years
⭕️Age of B is 2x years
⭕️Age of A is (2x + 2) years
Now...
=2x+2+2x+x=27
⭕️simplifying...
=5x=27-2
=5x=25
⭕️Therefore
x=5
⭕️hence....
️ age of C is 5 years
️Age of B is 2 x= 10 years
️Age of A is (2x + 2)
=10+2
=12 years

• Let age of C b (x) years
• Age of B be (2x) years
• Age of A be (2x + 2) years
___________ [ ASSUME ]
We have to find the age of B.
______________________________
》 Total ages of A, B and C is 27.
According to question,
=> 2x + 2 + 2x + x = 27
=> 5x + 2 = 27
=> 5x = 27 - 2
=> 5x = 25
=> x = 5
So,
️Age of C = x = 5 years
️Age of B = 2x = 2(5) = 10 years
️Age of A = (2x + 2) = [2(5) + 2)
=> 10 + 2 = 12 years
_____________________________
Age of B = 10 years.
Option A) 10 years.
