The thresher 'A' has output capacity of 170 kg h⁻¹ while threshing paddy crop at 14% moisture content (m.c.) with a grain to straw ratio 45:55. The thresher 'B' has output capacity of 160 kg h⁻¹ while threshing paddy crop at 13% m.c. with a grain to straw ratio 40:60. Both the threshers have threshing efficiency of 97%. If a farmer has to carry out threshing of paddy crop at 12% m.c. with a grain to straw ratio 40:60 in the least time, the selected thresher and its output in kg when operated for 5 hours will be
