Answers & Solutions:

1) Answer (C)

Each number is of the form $(n^3+1)$ where $n$ is a natural number

$1^3+1$ = 2

$2^3+1$ = 9

$3^3+1$ = 28

$4^3+1$ = 65

$5^3+1$ = 126

=> Ans – (C)

2) Answer (C)

The pattern here followed is :

1 * 3 + 2 = 5

5 * 3 + 2 = 17

17 * 3 + 2 = 53

53 * 3 + 2 = 161

161 * 3 + 2 = 485

485 * 3 + 2 = 1457

3) Answer (E)

Expression : $54.786 \div 10.121 \times 4.454 = ?$

= $\frac{55}{10} \times 4.5$

= $24.75 \approx 24$

4) Answer (C)

The pattern here followed is :

2 * 2 + 1 = 5

5 * 2 + 1 =  11

11 * 2 + 1 = 23

23 * 2 + 1 = 47

47 * 2 + 1 = 95

95 * 2 + 1 = 191

5) Answer (C)

The pattern here followed is :

1 * 3 + 1 = 4

4 * 3 + 2 = 14

14 * 3 + 3 = 45

45 * 3 + 4 = 139

139 * 3 + 5 = 422

422 * 3 + 6 = 1272

6) Answer (E)

$C.I. = P [(1 + \frac{R}{100})^T – 1]$

= $9000 [(1 + \frac{11}{100})^2 – 1]$

= $9000 [(1.11)^2 – 1]$

= $9000 \times (1.2321 – 1)$

= $9000 \times 0.2321$ = Rs. $2,088.90$

7) Answer (D)

Odd multiples of $\frac{1}{2}$ are multiplied

16 $\times \frac{1}{2}$ = 8

8 $\times \frac{3}{2}$ = 12

12 $\times \frac{5}{2}$ = 30

30 $\times \frac{7}{2}$ = 105

105 $\times \frac{9}{2}$ = 472.5

8) Answer (B)

Each number is multiplied by 2 and then consecutive natural numbers are added

2 $\times 2 + 1$ = 5

5 $\times 2 + 2$ = 12

12 $\times 2 + 3$ = 27

27 $\times 2 + 4$ = 58

58 $\times 2 + 5$ = 121

9) Answer (C)

The pattern is :

18 $+ 1.7 \times 2^0$ = 19.7

19.7 $- 1.7 \times 2^1$ = 16.3

16.3 $+ 1.7 \times 2^2$ = 23.1

23.1 $- 1.7 \times 2^3$ = 9.5

9.5 $+ 1.7 \times 2^4$ = 36.7

10) Answer (A)

Cubes of consecutive natural numbers are added

68 $+ 1^3$ = 69

69 $+ 2^3$ = 77

77 $+ 3^3$ = 104

104 $+ 4^3$ = 168

168 $+ 5^3$ = 293

11) Answer (A)

Case 1 : 6 at left end and 5 is at right end : 6 _ _ _ _ 5

Now, four empty places can be filled by 2,9,7 and 4 in = $4!$ ways

= $4 \times 3 \times 2 \times 1 = 24$

Case 2 : 6 at right end and 5 at left end : 5 _ _ _ _ 6

Similarly, no. of ways = $4!$

= $4 \times 3 \times 2 \times 1 = 24$

$\therefore$ Total no. of ways = $24 + 24 = 48$

12) Answer (E)

$\frac{(x)^{0.6}}{104}=\frac{26}{(x)^{1.4}}$

${(x)^{0.6}} * {(x)^{01.4}}$ = 104*26

${(x)^{2}}$ = 104*26

x = ±52

13) Answer (B)

Given values are ,
$\frac{1}{2}$ = 0.5

$\frac{7}{8}$ = 0.87

$\frac{3}{4}$ = 0.75

$\frac{5}{6}$ = 0.83

$\frac{6}{7}$ = 0.86

∴ Required difference = $\frac{7}{8}$ – $\frac{1}{2}$ = (7-4)/8 = 3/8

14) Answer (B)

Here

$(46)^2$ = 2116

$(11)^3$ = 1331

So, 2116 – 1331 = 785

15) Answer (B)

Number of the form $(2^n + 1)$ are added where n is even number

9 $+ (2^0 + 1)$ = 11

11 $+ (2^2 + 1)$ = 16

16 $+ (2^4 + 1)$ = 33

33 $+ (2^6 + 1)$ = 98

98 $+ (2^8 + 1)$ = 355

16) Answer (A)

We can note that consecutive prime numbers are either added or subtracted starting from 5.

65+5 = 70

70-7 = 63

63+11 = 74

74-13 = 61

61+17 = 78

Option A is the right answer.

17) Answer (D)

13*1 + 1 = 14

14*2 +2 = 28+2 = 30

30*3 + 3 = 90+3 =93

93*4 + 4 = 372+4 = 376

Option D is the right answer.

18) Answer (C)

14 – 8 = 6

25 – 14 =11

46 – 25 = 21

82 – 46 = 36

Let us take a look at the second order difference.

11 – 6 = 5

21 – 11 = 10

36 – 21 = 15

The next term will be 20. The difference will be 36 + 20 = 56.

The required term is 82 + 56 = 138.

Option C is the right answer.

19) Answer (E)

14*0.5 + 1 = 7+1= 8

8*1 – 1 = 8-1 = 7

7*1.5 + 1 = 10.5 + 1 = 11.5

11.5*2 – 1 = 23 – 1 = 22

22*2.5 +1 = 55+1 =56

Option E is the right answer.

20) Answer (A)

The given equation can be written as $\frac{120}{8}+\frac{75}{5} – 25 =x$

$15+15-25=5$

Option A is the right answer.

21) Answer (A)

The given equation can be written as$ \frac{\sqrt{625}*18}{15}$

=$\frac{25*6}{5}$

= 30.

Option A is the right answer.

22) Answer (A)

80.04 ~ 80

150.16 ~ 150

60.02 ~ 60

50.07 ~ 50

Now, (80.04% of 150.16 + 60.02% of 50.07) is equivalent to (80% of 150 + 60% of 50) = 120 +30 = 150

23) Answer (A)

The given equation can be written as $18^{2} + \frac{4*90}{5}$

= $324 + 4*18$

= $396$

Option A is the right answer.

24) Answer (D)

The given statement can be written as $90 + 60 – 151 = \sqrt[3]{?}$

$9 =\sqrt[3]{?}$

=> ? = 729

Option D is the answer.

25) Answer (A)

The series can be shown as below

1 8 3 6 5 4 7 2 9
1 8 3 6 5 4 7 2
1 8 3 6 5 4 7
1 8 3 6 5 4

After this, the series has to repeat itself and hence, the next term will be 1

26) Answer (C)

$\frac{26}{2/1}-1$ = 12

$\frac{12}{2/2}-1$ = 11

$\frac{11}{2/3}-1$ = 15.5

$\frac{15.5}{2/4}-1$ = 30

$\frac{30}{2/5}-1$ = 74

27) Answer (B)

The difference between consecutive terms is doubling.

For example, 9.4 – 8 = 1.4
12.2 – 9.4 = 2.8
17.8 – 12.2 = 5.6
29 – 17.8 = 11.2

Hence, the term to come next is 29 + 11.2*2 = 51.4

28) Answer (E)

16 = 17*1 – 1

30 = 16*2 – 2

87 = 30*3 – 3

344 = 87*4 – 4

So, the next number is 344*5 – 5 = 1715

29) Answer (B)

$13 \times 0.5 + 6.5 = 13$

$13 \times 1 + 7 = 20$

$20 \times 1.5 + 7.5 = 37.5$

$37.5 \times 2 + 8 = 83$

$83 \times 2.5 + 8.5 = 216$

30) Answer (B)

+The difference between the consecutive terms is:
31-29 = 2
37 -31 = 6
49- 37 = 12
69-49 = 20
Here, the difference between the consecutive difference terms is
6-2 = 4
12-6 = 6
20-12 = 8
Hence, the next term in difference series = 10
Therefore the next term in series = 69+30 = 99
