23. (d) 582 × 5 + 5 = 2910 + 25 = 2935
2
The pattern of number series is as follows : 2935 × 4 + 4 = 11740 + 16 = 11756
2
7 × 2 – 2 = 12 11756 × 3 + 3 = 35268 + 9 = 35277
12 × 4 – (2 + 6) = 48 – 8 = 40 25. (e)
40 × 6 – (8 + 10) = 240 – 18 = 222 The pattern of number series is as follows:
3
222 × 8 – (18 + 14) = 1776 – 32 = 1744 ≠ 1742 9050 – 15 = 9050 – 3375 = 5675
3
1744 ×10 – (32 + 18) = 17440 – 50 = 17390 5675 – 13 = 5675 – 2197 = 3478
3
24. (c) 3478 – 11 = 3478 – 1331 = 2147
3
The pattern of number series is as follows : 2147 – 9 = 2147 – 729 = 1418
2
3
6 × 7 + 7 = 42 + 49 = 91 1418 – 7 = 1418 – 343 = 1075 ≠ 1077
2
91 × 6 + 6 = 546 + 36 = 582 ≠ 584
