Answer:

22

Step-by-step explanation:

let John's age is x and bob's y

mary's age = 2x=y/2............(1)

After 22 years.......john's age is x+22 and bob's age is y+22

According to given info.  2(x +22) = y +22

from (1) y = 4x

i.e., 2x + 44 = 4x + 22

4x + 44 = 2x + 22

2x  = 22

x = 11

Mary's age is 2x i.e., 2*11 = 22
