 mousumi roy   For machine X100 X -> 1 min1000 X -> 10 min + 5 min clean = 15 minSo, 9000 X -> 15*9 = 135 minBut the last 5 min would be for cleaningSo, 9000 X can be produced by X in 130 minFor machine Y75 Y -> 1 minSo, 1500 Y -> 20 min + 10 min rest = 30 minSo, 9000 Y -> 30*6 = 180 minBut the last 10 min would be for rest. So, 9000 Y can be made in 170 minDesired Answer = Max(min(X,Y)) = Max(130,170) = 170 min 6 years ago
