Q2 The coach of a swim team needs to assign swimmers to a 200-yard medley

relay team (four swimmers, each swims 50 yards of one of the four strokes).

Since most of the best swimmers are very fast in more than one stroke, it is

not clear which swimmer should be assigned to each of the four strokes. The

five fastest swimmers and their best times (in seconds) they have achieved in

each of the strokes (for 50 yards) are

availability of 60 kg of raw material and 96 labour hours. One unit of

product A sold yields Rs.40 and one unit of product B sold gives Rs.35
