both pipe filling work in 1 hour=[1/14+1/16]=15/112   so,time both pipe take to full the tank =112/15hour=7hour28minute   because of hole time taken to fill the tank=7 hour 28 minutes+32 minute=8 hour   all three resultant work in 1 hour=1/8   hole 1 hour empty work=[15/112-1/8]=1/112   so time taken to empty the full tank=112 hours   answer 112
