    Let the present ages of A, B and C be a, b and c respectively Given that a:b = 3:4 a:c = 1:2 So , we can say that a:b:c = 3:4:6 so a = 3y, b = 4y , c= 6y 6 years hence age of a = 3y+6 b = 4y + 6 c = 6y + 6 it is given that (3y+6) + (4y+6) + (6y+6) = 96 13y + 18 = 96 y = 6 so present age of A is = 3x6 = 18 years
