Answers :

Direction (1-5) :

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 â€“ 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 â€“ 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 â€“ 2640)/10500] * 100 = 74.857 % = 75 % more

Direction (6-10) :

6) Answer: b)

13 + 43 = 77

77 + 53 = 202

202 + 63 = 418

418 + 73 = 761

761 + 83 = 1273

The wrong term is 763

7) Answer: b)

53760 Ã· 8 = 6720

6720 Ã· 7 = 960

960 Ã· 6 = 160

1050 * 4.5 = 4725

4725 * 5.5 = 25987.5

The wrong term is 1040

9) Answer: b)

182 + 1 = 325

192 + 1 = 362

202 + 1 = 401

212 + 1 = 442

222 + 1 = 485

232 + 1 = 530

The wrong term is 484

10) Answer: a)

19 * 1 + 1 = 20

20 * 2 + 2 = 42

42 * 3 + 3 = 129

129 * 4 + 4 = 520

520 * 5 + 5 = 2605

The wrong term is 45
