   4.17:40
   5.None of these
   
   Answer & Explanation

   Answer – 2.168:125
   Explanation :
   Economy = 12% of 500000 = 60,000
   Boys in Economy = 56% of 60,000 = 33600
   HM =25% of 500000 = 1,25,000
   Girls in HM = 20% of 1,25,000 =  25000
   336:250 = 168:125
   
   
   
2. What is the difference between the no of girls in IT  and no of girls in ECE ?
   1.2100

   4.4800
   5.None of these
   
   Answer & Explanation

   Answer – 4.4800
   Explanation :
   No of student in ECE = 16 % of 5,00,000 = 80,000
   Girls in ECE = 29% of 80,000 = 23200
   No of Students in IT = 14 % of 5,00,000 = 70,000
   Girls in IT = 40% of 70,000 = 28000
   Difference = 28000 – 23200 = 4800
   
   
   
3. The number of boys in CS is approximately what % of total number of students in EEE ?
   1.36%
   2.41%
   3.27%
   4.30%
   5.None of these
   
   Answer & Explanation

   Answer – 1.36%
   Explanation :
   No of students in CS = 15% of 5,00,000 = 75000
   Boys in CS = 43% of 75000 = 32250
   No of Students in EEE = 18% of 5,00,000 = 90,000
   % of Boys = 32250*100/90,000 = 35.8 = 36%
   
   
   
4. What is the average number of girls students in the fields ECE, EEE and Hotel Management ?

   Answer & Explanation

   Answer – 3.26,566
   Explanation :
   Girls in ECE = 23,200
   Girls in EEE = 31,500
   Girls in HM = 25,000
   Average = 79700/3 = 26,566.66 = 26,566
   
   
   
5. The large number of girls students distributed in which field ?
   1.ECE
   2.CS
   3.Hotel Management
   4.IT
   5.None of these
   
   Answer & Explanation

   Answer – 2.CS
   Explanation :
   Girls in ECE = 23,200
   Girls in EEE = 31,500
   Girls in HM = 25,000
   Girls in CS = 42,750
   Girls in IT = 28,000
   Girls in Economy = 26,400
   
   
   

II.Study the following table carefully to answer the following questions given below

6. The average no of Engineering graduates and commerce graduates in CTS was 520. What was the total no of employees in CTS ?
   1.960
   2.1920
   3.1250
   4.1600
   5.None of these
   
   Answer & Explanation

   Answer – 4.1600
   Explanation :
   Engineering Graduates in CTS = 100-75 = 25%
   65% = 2*520 = 1040
   100% = 1040*100/65 = 1600
   
   
   
7. If the ratio of no of commerce graduates to that of Engineering  graduates in Wipro was 9:6, what was the no of engineering graduates in Wipro ?
   1.588
   2.466
   3.755
   4.634
   5.None of these
   
   Answer & Explanation

   Answer – 1.588
   Explanation :
   Wipro = 2110
   Commerce+Engineering graduates in Wipro = 100-30 = 70%
   Engineering graduates = 70*6/15 = 28% = 28% of 2100 = 588
   
   
   
8. If the difference between the no of Engineering graduate employees in Infosys and that in HCL was 300. What was the total no of employees in HCL. Assume no of employees in HCL and Infosys are same ?

   3.900
   4.1000
   5.None of these
   
   Answer & Explanation

   Answer – 4.1000
   Explanation :
   % of Engineering student in  HCL = 100-50 = 50%
   Difference between the no of Engineering  graduates  in Infosys and that in HCL = 50-20 = 30%
   X *30/100 = 200
   X = 300*100/30 = 1000
