Correct Option: B

Number of men working in night shifts in different industries will be as below.
As per given graphs in question,
Number of total people working in night shifts in IT = 40250 x 12%
Number of men working in night shifts in IT = 40250 x 12% x (100% - 20% )
Number of men working in night shifts in IT = 40250 x 12% x 80%
⇒ Number of men working in night shifts in IT = 40250 x (12/100) x 80/100
⇒ Number of men working in night shifts in IT = 3864
Similarly,
Number of men working in night shifts in Sports = 80/100 x 18/100 x 40250 = 5796
Number of men working in night shifts in Call Center = 55/100 x 32/100 x 40250 = 7084
Number of men working in night shifts in Sales = 40/100 x 8/100 x 40250 = 1288
Number of men working in night shifts in Banking = 60/100 x 14/100 x 40250 = 3381
Number of men working in night shifts in Chemical Industries = 85/100 x 16/100 x 40250 = 5474
Hence, total number of men working in night shifts in different industries = 3864 + 5796 + 7084 + 1288 + 3381 + 5474 = 26887
