Mark me as brain lies

Answer 2

Answer:

22

Explanation:

Let the age of A is A year

lat the age of B of B year

let the age of C is C year

according to question,

b=a+2 a=b-2

b=c-5. c=b+5

now,. a+b+c/3=18

a+b+c=54

b - 2 + b + b + 5 = 54

3b + 3 = 54

3b = 51

b=51/3

b= 17

age of c is b+5=17+5=22
