Answers:
Directions (1-5):
1) Answer: BÂ Â Â Â Â Â
12 + 33 = 39
39 + 53 = 164
164 + 73 = 507 (not 500)
507 + 93 = 1236
1236 + 113 = 2567
2) Answer: C
251 + 25 = 276
276 – 20 = 256 (not 257)
256 + 15 = 271
271 – 10 = 261
261 + 5 = 266
3) Answer: B
28 + 7 = 35
35 + 14 = 49 (not 42)
49 + 21 = 70
70 + 28 = 98
98 + 35 = 133
4) Answer: D
23 + 1 = 9
33 – 1 = 26
43 + 1 = 65
53 – 1 = 124 (not 120)
63 + 1 = 217
73 – 1 = 342
5) Answer: A
13 + 2 = 3
23 + 4 = 12
33 + 6 = 33
43 + 8 = 72
53 + 10 = 135
63 + 12 = 228 (not 230)
Directions (6-10):
6) Answer: C
Average students from E=600 + 540 + 480/3=540
Average students from D=560 + 360 + 460/3=460
Required percentage = [(540 – 460)/460] * 100=17%
7) Answer: B
Number of students from A, B and D in EEE = (520 + 420 + 360) = 1300
Number of students from B, C and E in ECE = (600 + 540 + 480) = 1620
Difference = 1620 – 1300 = 320
8) Answer: A
Required percentage
= [480/(420 + 360 + 480 + 560 + 600)] * 100
= 20%
9) Answer: B
Average = (460 + 600 + 540 + 460 + 480)/5
=508
10) Answer: C
Required ratio = (460 + 600 + 460) : (420 + 420 + 540)
=1520 : 1380
=76 : 69
