Total numbers of workers in the industry is 1000
So, workers of shift 1+ workers of shift 2 + Workers of shift 3 =1000 Workers of shift 3 in Monday = 1000 - (300 + 520) = 180 Workers of shift 2 in Tuesday = 1000 - (270 + 470) = 260 Workers of shift 3 in Wednesday = 1000 - (350 + 450) = 200 Workers of shift 2 in Thursday = 1000 - (400 + 250) = 350 Workers of shift 1 in Friday = 1000 - (420 + 330) = 250 Workers of shift 3 in Saturday= 1000 - (500 + 250) = 250 a)The numbers of workers worked on Tuesday in shift 2 = 260 b)Numbers of workers in shift 2 =(520 + 260 + 450 + 350 + 420 + 250 ) = 2250 c)Total numbers of workers in shift 3 =( 180 + 470 + 200 + 250 + 330 + 250 ) = 1680

d) Total number of workers who worked on Saturday in shift 3 = 1000 - (500 + 250) = 250
