Two taps A and B can fill a tank in 40 min and 64 min respectively. Both taps are opened together but due to some problem they work 13/16 and 7/10 of their efficiencies, after some time the problem was removed, the cistern is filled in 22 minutes from that moment. For how long did the

taps flow with less efficiency?
