What should come in place of the question mark (?) in the following number series ?
1548, 516, 129, 43, ?
11
10.75
9.5
12
None of these
The numbers are alternatively divided by 3 and 4
1548 $$\div 3$$ = 516
516 $$\div 4$$ = 129
129 $$\div 3$$ = 43
43 $$\div 4$$ = 10.75
949, 189.8, ?, 22.776, 11.388, 6.8328
48.24
53.86
74.26
56.94
The pattern followed is :
949 $$\times 0.2$$ = 189.8
189.8 $$\times 0.3$$ = 56.94
56.94 $$\times 0.4$$ = 22.776
22.776 $$\times 0.5$$ = 11.388
11.388 $$\times 0.6$$ = 6.8328
121, 144, 190, 259, ?, 466
351
349
374
328
Multiples of 23 are added.
121 $$+ 23 \times 1$$ = 144
144 $$+ 23 \times 2$$ = 190
190 $$+ 23 \times 3$$ = 259
259 $$+ 23 \times 4$$ = 351
351 $$+ 23 \times 5$$ = 466
14, 43.5, 264, ?, 76188

The given number series is based on the following pattern :
14 $$\times 3 + 1.5$$ = 43.5
43.5 $$\times 6 + 1.5 \times 2$$ = 264
264 $$\times 12 + 1.5 \times 4$$ = 3174
3174 $$\times 24 + 1.5 \times 8$$ = 76188
41, 164, 2624, ?, 6045696
104244
94644
94464
102444
Squares of even numbers are multiplied.
41 $$\times 2^2$$ = 164
164 $$\times 4^2$$ = 2624
2624 $$\times 6^2$$ = 94464
94464 $$\times 8^2$$ = 6045696
What should come in place of the question mark (?) in the following questions ?
(47 × 588) ÷ (28 × 120) = ?
6.284
7.625
8.225
8.285
Expression : (47 × 588) ÷ (28 × 120) = ?
= $$\frac{47}{120} \times \frac{588}{28}$$
= $$\frac{47}{120} \times 21$$
= $$\frac{987}{120} = 8.225$$
45% of 224 × ?% of 120 = 8104.32
67
02
59
71
Expression : 45% of 224 × ?% of 120 = 8104.32
=> $$(\frac{45}{100} \times 224) \times (\frac{x}{100} \times 120) = 8104.32$$
=> $$100.8 \times 1.2x = 8104.32$$
=> $$x = \frac{8104.32}{120.96} = 67$$
$$7921 \times 51+ 374 = (?)^{3}$$
16
19
15
21
Expression : $$7921 \times 51+ 374 = (?)^{3}$$
=> $$403971 + 374 = (x)^3$$
=> $$x^3 = 404345$$
=> $$x = \sqrt[3]{404345} = 73.9 \approx 74$$
$$6573 \div 21 \times (0.2)^{2} = ?$$
7825
62.6
1565
12.52
Expression : $$6573 \div 21 \times (0.2)^{2} = ?$$
= $$\frac{6573}{21} \times 0.04$$
= $$313 \times 0.04$$
= $$12.52$$
74156 - ? - 321- 20 + 520 = 69894
3451
4441
5401
4531
Expression : 74156 - ? - 321- 20 + 520 = 69894
=> $$74676 - x - 341 = 69894$$
=> $$x = 74335 - 69894$$
=> $$x = 4441$$
