Answers :
1) Answer: A
The total number of students enrolled for MBA course from institute A and C together
= > 40000*(27/100) = 10800
The total number of students successfully completed the course from institute B and D together
= > 32000*(34/100) = 10880
Required difference = 10880 – 10800 = 80
2) Answer: D
Institute A = > Successful % = (4160/4800)*100 = 86.667 %
Institute B = > Successful % = (6400/7200)*100 = 88.889 %
Institute C = > Successful % = (5760/6000)*100 = 96 %
Institute D = > Successful % = (4480/6400)*100 = 70 %
Institute E = > Successful % = (6080/8800)*100 = 69.09 %
Institute F = > Successful % = (5120/6800)*100 = 75.29 %
Institute C has highest percentage of successful candidates.
3) Answer: C
The total number of candidates not completed the course from institute D
= > [40000*(16/100)] – [32000*(14/100)]
= > 6400 – 4480 = 1920
The total number of candidates not completed the course from institute F
= > [40000*(17/100)] – [32000*(16/100)]
= > 6800 – 5120 = 1680
Required ratio = 1920 : 1680 = 8 : 7
4) Answer: A
Total number of candidates enrolled for MBA course from institute B and E together
= > 40000*(40/100) = 16000
Total number of candidates successfully completed the course from institute A and C together
= > 32000*(31/100) = 9920
Required % = (16000/9920)*100 = 161.29 % = 160 %
5) Answer: D
The average number of students enrolled for institute C, D and F together
= > 40000*[(15 + 16 + 17)/100]*(1/3) = 6400
The average number of students successfully completed the course from institute C, D and E together
= > 32000*[(18 + 14 + 19)/100]*(1/3) = 5440
Required difference = 6400 – 5440 = 960
