Required ratio = number of units manufactured in the year 2004 / number of units manufactured in the year 2008
Required ratio = 4.5 : 7 = 45 : 70 = 9 : 14
Required percentage = (Advertisement charges % - Commission charges%) x 100/ Advertisement charges
Required percentage = (18 - 15 ) x 100/18 = 3 x 100 /18 = 100/6 = 162/3%
From above diagram ,
The total number of students who come to school by car is represented in pie chart = 70°
The total number of students who come to school by bus is represented in pie chart = 90°
Required ratio = 70° : 90° = 7 : 9 = 21 : 27
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
In 2007, income of Company A = Rs. 13,54,300 and their profit = Rs. 6,00,000
