Answers :
Directions (1-5)Â :
1) Answer: A
Series I,
12 * 2.5 = 30
30 * 2.5 = 75
75 * 2.5 = 187.5
187.5 * 2.5 = 468.75
Series II,
2 is the 1st term
2 * 2.5 = 5
5 * 2.5 = 12.5
12.5 * 2.5 = 31.25
31.25 * 2.5 = 78.125
78.125 is the 5th term
2) Answer: B
Series I,
8640/6 = 1440
1440 / 5 = 288
288 / 4 = 72
72 / 3 = 24
Series II,
1560 is the 1st term
1560 / 6 = 260
260 / 5 = 52
52 / 4 = 13
13 is the 4th term
3) Answer: A
Series I,
25 * 1 + 1 = 26
26 * 2 + 2 = 54
54 * 3 + 3 = 165
165 * 4 + 4 = 664
664 * 5 + 5 = 3325
Series II,
7 is the 1st term
7 * 1 + 1 = 8
8 * 2 + 2 = 18
18 * 3 + 3 = 57
57 is the 4th term.
4) Answer: C
Series I,
14 * 3 + 10 = 52
52 * 2.5 + 10 = 140
140 * 2 + 10 = 290
290 * 1.5 + 10 = 445
Series II,
2 is the 1st term.
2 * 3 + 10 = 16
16 * 2.5 + 10 = 50
50 * 2 + 10 = 110
110 * 1.5 + 10 = 175
175 is 5th term.
5) Answer: D
Series I,
8 + 132Â = 177
177 + 112Â = 298
298 + 92Â = 379
379 + 72Â = 428
428 + 52Â = 453
Series II,
11 is 1st term.
11 + 132Â = 180
180 + 112Â = 301
301 is 3rd term.
Directions (6-10) :
6) Answer: B
(0.2)48 ÷ (0.04)16 * (0.008)2 = (0.2)?
(0.2)48Â /(0.2)32Â * (0.2)3 * 2Â = (0.2)?
(0.2)48 – 32 + 6 = (0.2)?
? = 22
7) Answer: E
80 % of 605 – 14.285 % of 420 + √1444 * √16 = ? * √576
484 – 60 + 152 = ? * 24
24 = ?
8) Answer: A
52 * 8 – 90 % of 40 = ? + 18 * √841
416 – 36 = ? + 522
? = -142
9) Answer: D
120% of700 + 60% of 385 – ? = 37 * 19
840 + 231 – ? = 703
? = 368
10) Answer: A
12.5% of 560 + 83.33% of 138 + 62.5% of 552 = ?
1/8 * 560 + 5/6 * 138 + 5/8 * 552 = ?
