Answers :
1) Answer: D
24 * 2 – 3 = 45
45 * 3 – 2 = 133
133 * 4 – 1 = 531
531 * 5 – 0 = 2655
2655 * 6 – (-1) = 15931
2) Answer: D
10 + (2 * 3) = 16
16 + (3 * 4) = 28
28 + (4 * 5) =Â 48
48 + (5 * 6) = 78
78 + (6 * 7) = 120
3) Answer: A
781 – 152 = 556
556 – 132 = 387
387 – 112 = 266
266 – 92 = 185
185 – 72 = 136
4) Answer: E
123 – 12 = 1716
133 – 14 = 2183
143 – 16 = 2728
153 – 18 = 3357
163 – 20 = 4076
173 – 22 = 4891
5) Answer: B
7 + (19 * 2) = 45
45 + (17 * 3) = 96
96 + (13 * 4) = 148
148 + (11 * 5) = 203
203 + (7 * 6) =Â 245
6) Answer: C
719.909 ÷ √15.61 + 119.91% of 199.98 = ? + 32.891 * √99
180 + 240 = ? + 330
? = 90
7) Answer: E
31.05% of 599.879 + 2609.91 ÷ 86.911 + 63.912 % of 124.913 = ?
186 + 30 + 80 = ?
296 = ?
8) Answer: C
√624 % of 320.09 + √195 * 7.912 – 1007.99 ÷ √325 = ?
80 + 112 – 56 = ?
136 = ?
9) Answer: C
34.91 % of 480.081 + ? * √170 = √120 * (429.181 ÷ 12.981)
168 + ? * 13 = 11 * 33
? * 13 = 195
? = 15
10) Answer: C
120.981 – √530 * 4.989 + 405.912 ÷ √840 = ?
121 – 115 + 14 = ?
