present ages are 4x:5x
6 years after= 4x+6:5x+6
4x+6/5x+6 = 14/17
17(4x+6)=14(5x+6)
68x+102= 70x+84
70x-68x =102-84
2x=18
x=18/2
x=9years
present ages= 4(9):5(9)
=36:45 years
after 12 years
=36+12:45+12
=48:57 is ratio
6 years after= 4x+6:5x+6
4x+6/5x+6 = 14/17
17(4x+6)=14(5x+6)
68x+102= 70x+84
70x-68x =102-84
2x=18
x=18/2
x=9years
present ages= 4(9):5(9)
=36:45 years
after 12 years
=36+12:45+12
=48:57 is ratio
