SOLUTIONS

1. Answer (d)
Explanation :
(221-1)/4 = 55
(55+1)*4 = 224
(224-4)/4 = 55
(55+4)*4 = 236
(236-7)/4 = 57.25
(57.25+7)*4 = 257

2. Answer (a)
Explanation :
5 * 1 + 2 + 1 = 8
8 * 1.5 + 4 – 1 = 15
15 * 2 + 6 + 1 = 37
37 * 2.5 + 8 – 1 = 99.5
99.5 * 3 + 10 + 1 = 309.5

3. Answer (c)
Explanation :
3 + 1³ – 2 = 2
2 + 2³ + 4 = 14
14 + 3³ – 6 = 35
35 + 4³ + 8 = 107

4. Answer (c)
Explanation :
664 + 4 ÷ 2 = 334
334 + 8 ÷ 4 = 85.5
85.5 + 12 ÷ 6 = 16.25
16.25 + 16 ÷ 8 = 4.03125
4.03125 + 20 ÷ 10 = 2.403125

5. Answer (b)

774 + 3 × 23 = 843
843 + 4 × 23 = 935
935 + 5 × 23 = 1050
? = 1050 + 6 × 23 = 1050 + 138 = 1188
