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
