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 – 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 % = 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 ÷ 8 = 6720
6720 ÷ 7 = 960
960 ÷ 6 = 160
160 ÷ 5 = 32
32 ÷ 4 = 8
The wrong term is 80
8) Answer: b)
80 * 1.5 = 120
120 * 2.5 = 300
300 * 3.5 = 1050
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
