Answers :
Directions (1-6) :
1) Answer: a)
Total number of CSE students =2000
Number of CSE students from A and C = 2000 – 580 – 360 = 1060
Number of CSE students from C = 32/53 * 1060 = 640
Number of ME students from C = 2000 – 640 – 540 – 440 = 380
2) Answer: d)
Number of EEE students from B = 1900 – 440 – 540 – 560 = 360
Number of ME students from B = 1700 – 580 – 360 – 280 = 480
3) Answer: e)
Number of ME students from B and C = 2000 – 680 – 460 = 860
Number of ME students from C = 19/43 * 860 = 380
Number of CSE students from C = 2000 – 540 – 440 – 380 = 640
4) Answer: c)
Required percentage = 440/2000 * 100 = 22%
5) Answer: b)
Total number of ECE students = 430 * 4 = 1720
Number of ECE students from D = 680
Number of ECE students from A = 1720 – 280 – 440 – 680 = 320
Required ratio = 320: 360 = 8: 9
6) Answer: a)
Number of EEE and ME students from B = 1700 – 580 – 280 = 840
Number of CSE and ME students from C = 2000 – 540 – 440 = 1020
Difference = 1020 – 840 = 180
Directions (7-10) :
7) Answer: d)
(4 + 2) * 1 = 6
(6 + 3) * 2 = 18
(18 + 4) * 3 = 66
(66 + 5) * 4 = 284
(284 + 6) * 5 = 1450
8) Answer: a)
12 * 1.5 + 4 = 22
22 * 1.5 + 5 = 38
38 * 1.5 + 6 = 63
63 * 1.5 + 7 = 101.5
101.5 * 1.5 + 8 = 160.25
9) Answer: c)
18 + 62 = 54
54 + 52 = 79
79 + 42 = 95
95 + 32 = 104
104 + 22 = 108
10) Answer: d)
103 – 5 = 995
93 – 6 = 723
83 – 7 = 505
73 – 8 = 335
63 – 9 = 207
53 – 10 = 115
