Question : Pipe X can fill a tank in 20 hours and pipe Y can fill the tank in 35 hours. Both the pipes are opened at alternate hours. If pipe Y was opened first, then how much time (in hours) does it take to fill the tank?
Option 1: $\frac{269}{11}$
Option 2: $\frac{286}{11}$
Option 3: $\frac{179}{7}$
Option 4: $\frac{172}{7}$
