Answers & Solutions:

1)Â AnswerÂ (A)

SeriesÂ :Â OTE, PUF, QVG, RWH, ?

The pattern followed in each letter of the terms isÂ :

1st letterÂ : O (+1 letter) = PÂ (+1 letter) =Â QÂ (+1 letter) =Â RÂ (+1 letter) =Â S

2nd letterÂ : TÂ (+1 letter) =Â UÂ (+1 letter) =Â VÂ (+1 letter) =Â WÂ (+1 letter) =Â X

3rd letter : EÂ (+1 letter) =Â FÂ (+1 letter) =Â GÂ (+1 letter) =Â HÂ (+1 letter) =Â I

Thus, missing term = SXI

=> Ans – (A)

2)Â AnswerÂ (B)

Series :Â 16, 61, 25, 52, 36, 63, 49, ?

In pairs of two, square of natural numbers and their reverse is written.

EgÂ :- 16 and 61, 25 and 52, 36 and 63

Similarly, reverse of 49 =Â 94

=> Ans – (B)

3)Â AnswerÂ (A)

SeriesÂ :Â AFKPU, BGLQV, CHMRW, ??

The pattern followed in each letter of the terms isÂ :

1st letterÂ : A (+1 letter) = BÂ (+1 letter) =Â CÂ (+1 letter) =Â D

2nd letterÂ : FÂ (+1 letter) =Â GÂ (+1 letter) =Â HÂ (+1 letter) =Â I

3rd letter : KÂ (+1 letter) =Â LÂ (+1 letter) =Â MÂ (+1 letter) =Â N

4th letterÂ : PÂ (+1 letter) =Â QÂ (+1 letter) =Â RÂ (+1 letter) =Â S

5th letterÂ : UÂ (+1 letter) =Â VÂ (+1 letter) =Â WÂ (+1 letter) =Â X

Thus, missing term =Â DINSX

=> Ans – (A)

4)Â AnswerÂ (A)

Expression =Â 11 : 121 : : 12 : ?

The pattern followed is = $x:x^2$

EgÂ :-Â $11:(11)^2=11:121$

Similarly, $(12)^2=144$

=> Ans – (A)

5)Â AnswerÂ (A)

Expression =Â 15 : 256 : : 14 : ?

The pattern followed is = $x:(x+1)^2$

EgÂ :-Â $15:(15+1)^2=15:256$

Similarly, $(14+1)^2=(15)^2=225$

=> Ans – (A)

6)Â AnswerÂ (A)

Expression =Â 108 : 11664 : : 107 : ?

The pattern followed is = $x:x^2$

EgÂ :-Â $108:(108)^2=108:11664$

Similarly, $(107)^2=11449$

=> Ans – (A)

7)Â AnswerÂ (A)

The pattern followed isÂ that numbers of the form $(3\times2^n)$ are added.

2 $+(3\times2^0)$ = 5

5Â $+(3\times2^1)$ =Â 11

11Â $+(3\times2^2)$ =Â 23

23Â $+(3\times2^3)$ =Â 47

=> Ans – (A)

8)Â AnswerÂ (A)

The pattern followed is :

2 $+(1)^2$ = 3

3Â $+(2)^2$ =Â 7

7Â $+(3)^2$ =Â 16

16Â $+(4)^2$ =Â 32

32Â $+(5)^2$ =Â 57

=> Ans – (A)

9)Â AnswerÂ (C)

The pattern followed isÂ :

8Â + 3 =Â 11

11Â + 3 =Â 14

14Â + 3 =Â 17

17Â + 3 =Â 20

20 + 3 =Â 23

=> Ans – (C)

10)Â AnswerÂ (A)

The pattern followed isÂ :

18Â – 4 =Â 14

14Â – 4 =Â 10

10Â – 4 =Â 6

6 – 4 =Â 2

=> Ans – (A)

11)Â AnswerÂ (A)

The pattern followed isÂ :

3 $\times2+1$ = 7

7Â $\times2-1$ =Â 13

13Â $\times2+1$ =Â 27

27Â $\times2-1$ =Â 53

53Â $\times2+1$ =Â 107

=> Ans – (A)

12)Â AnswerÂ (B)

The pattern followed isÂ :

$(6)^2-1$ = 35

$(7)^2+1$ =Â 50

$(8)^2-1$ =Â 63

$(9)^2+1$ =Â 82

$(10)^2-1$ =Â 99

$(11)^2+1$ =Â 122

=> Ans – (B)

13)Â AnswerÂ (C)

The pattern followed isÂ :

14 $+(3)^2-1$ = 22

22Â $+(4)^2-1$ =Â 37

37Â $+(5)^2-1$ =Â 61

61Â $+(6)^2-1$ =Â 96

96Â $+(7)^2-1$ =Â 144

=> Ans – (C)

14)Â AnswerÂ (A)

The pattern followed isÂ :

263 + 14 = 277

277 + 13 = 290

290 + 12 = 302

302 + 11 = 313

313 + 10 =Â 323

=> Ans – (A)

15)Â AnswerÂ (B)

Expression =Â 431 : 12 : : 345 : ?

The pattern followed is that the second number is the product of digits of first number.

EgÂ :- $4\times3\times1=12$

Similarly,Â $3\times4\times5=60$

=> Ans – (B)
