Ans-(c):  Number of employees from HR department = \(25\times\cfrac{5200}{100}\)  = 1,300/
Number of graduate employees = \(1300\times\cfrac{45}{100}\) =585/

Number of post graduate employees = 1300 - 585 = 715

Number of employees from marketing department = \(12\times\cfrac{5200}{100}\)  = 624

Number of graduate employees = 312
Number of employees from finance department = \(18\times\cfrac{5200}{100}\)  = 936/
Number of post graduate employees = \(936\times\cfrac{75}{100}\)  = 702/
Number of graduate employees = 234

Number of employees from IT department = \(30\times\cfrac{5200}{100}\)  =1,560/
      
Number of post graduate employees = 546
Number of graduate employees = 1014
Number of employees from Legal department = \(15\times\cfrac{5200}{100}\)= 780
Number of graduate employees = \(60\times\cfrac{780}{100}\)=468
