9/14 part of tank is filled by C.
A is open for 2 hrs
B is open for 4 hrs
C is open for 6 hrs.

If C takes c hrs to fill the tank, then A takes 3c hrs and B takes 3c/2 hrs to fill the tank.
Tank filled by A,B and C are 2/3c , 8/3c and 6/c respectively.
2/3c + 8/3c +6/c = 1
c= 28/3 hrs
tank filled by tap C = 6/c= 6*3/28=18/28= 9/14 part of tank.
