Solution 1: C)
324 + 72 – 1 = 372
372 + 82 + 1 = 437
437 + 92 – 1 = 517
517 + 102 + 1 = 618
618 + 112 – 1 = 738
738 + 122 + 1 = 883
883 + 132 – 1 = 1051
618 should come in place of 620
Hence, option c.
Solution 2: C)
For I;
4 × 1 + 1 = 5
5 × 2 + 2 = 12
12 × 3 + 3 = 39
39 × 4 + 4 = 160
160 × 5 + 5 = 805
Therefore, For II:
1st term = 160
160 × 1 + 1 = 161
161 × 2 + 2 = 324
324 × 3 + 3 = 975
975 × 4 + 4 = 3904
Therefore, m = 3904
Hence, option c.
Solution 3: B)
632 + 7 × 9 = 695
695 – 9 × 11 = 596
596 + 11 × 13 = 739
739 – 13 × 15 = 544
544 + 15 × 17 = 799
Wrong term = 540
So, 10th term = 540 + 7 × 9 – 9 × 11 + 11 × 13 – 13 × 15 + 15 × 17 – 17 × 19 + 19 × 21 – 21 × 23 + 23 × 25 = 875
Hence, option b.
RBI Assistant 2023 Mains Free Mock Test
Solution 4: B)
58 × 1.5 = 87
87 × 2 = 174
174 × 2.5 = 435
435 × 3 = 1305
Similarly:
16 × 1.5 = 24
24 × 2 = 48
48 × 2.5 = 120
120 × 3 = 360
360 × 3.5 = 1260
So the value of m = 1260
Hence, option b.
Solution 5: B)
57 + 42 = 73,
73 + 52 = 98,
98 + 62 = 134,
134 + 72 = 183,
183 + 82 = 247,
247 + 92 = 328
Hence, option b.
Solution 6: C)
The given series follows the following pattern:
So, a = 96 and b = 100.
Since, b = 100, 5th term = 100 + 55
Hence, option c.
Solution 7: E)
2 × a = x
Or, 2 × 96 = x
So, x = 192
5th term of the given series = 107
So, required difference = 192 – 107 = 85
Hence, option e.
Solution 8: C)
Next term of the series = 173 + (45 × 3.5) = 330.5
{(330.5 – 96)/96} × 100 ~ 244%
Hence, option c.

Solution 9: D)
24 × 1 + 4 × 3 = 36
36 × 2 + 4 × 4 = 88
88 × 3 + 4 × 5 = 284
284 × 4 + 4 × 6 = 1160
1160 × 5 + 4 × 7 = 5828
Therefore, 88 should come in place of 84.
Hence, option d.
Solution 10: B)
124 + 56 = 180
180 + 72 = 252
252 + 56 = 308
308 + 72 = 380
380 + 56 = 436
Therefore, 436 should come in place of 416.
Hence, option b.
