Answers :
Directions (1-5):
1) Answer: E
420 + 32 =Â 452
452 – 16 = 436
436 + 8 = 444
444 – 4 = 440
440 + 2 = 442
442 – 1 = 441
2) Answer: A
28,      1468,     1708,     1756,       1768,         1772,     1774
1440Â Â Â Â Â Â Â Â 240Â Â Â Â Â Â Â Â Â Â Â 48Â Â Â Â Â Â Â Â Â Â 12Â Â Â Â Â Â Â Â Â Â Â Â Â 4Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 2
The difference is, ÷ 6, ÷ 5, ÷ 4, ÷ 3, ÷ 2,…
3) Answer: D
456 * (1/2) = 228
228 * (3/2) = 342
342 * (5/2) = 855
855 * (7/2) =Â 2992.5
4) Answer: B
152 + 102Â = 252
252 + 113Â = 1583
1583 + 122Â = 1727
1727 + 133Â =Â 3924
3924 + 142Â = 4120
5) Answer: C
18 * 1 + 2 = 20
20 * 2 + 3 = 43
43 * 3 + 4 = 133
133 * 4 + 5 = 537
537 * 5 + 6 =Â 2691
Directions (6-10) :
6) Answer: A
1120 ÷ 7 + (4/9) of 1890 + 18 % of 500 = x2 + 66
(1120/7) + (4/9) * 1890 + (18/100) * 500 = x2Â + 66
160 + 840 + 90 – 66 = x2
x2Â = 1024
x = 32
7) Answer: A
(858 + 316 + 578) ÷ 6 + 123 = x + 142
(1752 / 6) + 123 – 142 = x
x = 292 + 123 – 142 = 273
8) Answer: C
(3/8) of (48/21) of 105 = 14 % of 600 + (2/7) of x
(3/8) * (48/21) * 105 = (14 / 100) * 600 + (2x/7)
90 = 84 + (2x/7)
6 = (2x/7)
x = (6 * 7) / 2 = 21
9) Answer: B
5 (3/5) – 3 (7/10) + 8 (4/15) – 6 (4/5) + 7 (7/15) = x
x = (5 – 3 + 8 – 6 + 7) (3/5 – 7/10 + 4/15 – 4/5 + 7/15)
x = 11 [(18 – 21 + 8 – 24 + 14) / 30]
x = 11 (-5 / 30) = 11 (-1 / 6)
x = (66 – 1) / 6 = 65 /6
x = 10 (5/6)
10) Answer: D
17 × 4 × (45 – 38 + 5) + 312 ÷ 4 ÷ 3 – 282 = x
(17 * 4 * 12) + ((312 / 4) / 3) – 784 = x
x = 816 + 26 – 784 = 58
