Answer 1

Answer:

hope its help you

Step-by-step explanation:

Let 4:3 = 4x and 3x

Let 11:9 = 11/9

After 6 year age of A and B

4x +6/ 3x +6 = 11/9

9(4x+6)= 11(3x + 6)

36x+54 = 33x + 66

36x-33x = 66-54

3x = 12

x = 12/3

x = 4

hence present age of A and B is 4x = 4×4 =16

and 3x = 3×4 = 12.
