Answers:

1) Answer: C

The total number of candidates appeared for the interview from Commerce and Engineering discipline

= >30000 * [(54 + 79.2)/360] = 11100

Total number of candidates selected after the interview from Agriculture and Management discipline

= >8000 * [(20 + 15)/100] = 2800

Required difference = 11100 – 2800 = 8300

2) Answer: B

Total number of candidates appeared for the interview from Agriculture and Science discipline together

= >30000 * [(64.8 + 50.4)/360] = 9600

Total number of candidates selected after the interview from Engineering and Other discipline together

= >8000 * [(17 + 14)/100] = 2480

Required % = (9600/2480) * 100 = 387.096 % = 387 %

3) Answer: D

The total number of candidates appeared for the interview from Management discipline

= >30000 * (72/360)

The total number of candidates selected after the interview from Commerce discipline

= >8000 * (18/100)

Required ratio = [30000 * (72/360)]: [8000 * (18/100]

= 25: 6

4) Answer: A

The average number of candidates appeared for the interview from Science and Other discipline together

= >30000 * [(50.4 + 39.6)/360] * (1/2) = 3750

The average number of candidates selected after the interview from Agriculture and Science discipline together

= >8000 * [(20 + 16)/100] * (1/2) = 1440

Required difference = 3750 – 1440 = 2310

5) Answer: C

Total number of candidates appeared for the interview from Commerce and Management discipline together

= > 30000 * [(54 + 72)/360] = 10500

Total number of candidates selected after interview from Engineering and Science discipline together

= >8000 * [(17 + 16)/100] = 2640

Required % = [(10500 – 2640)/10500] * 100 = 74.857 %
