## Alphabetical Series Set 1 | Reasoning

Q.1. JAF, JEF, JIF, JOF, ?

1. PIG

2. JET

3. JUF

4. JOF

Sol : Option 3

The middle letters which are vowels have an increasing trend of A, E, I, O, U and remaining letters have been retained as it is.So answer would be JUF.

1. xxxyy

2. yxyxy

3. yyxxy

4. yyyxx

1. OPKL

2. AYBZ

3. JIRQ

4. LRMS

Sol : Option 1

Start reading from CD, EF, GH, IJ, KL and then QR, ST, UV, WX, YZ and so on after splitting the groups.

Q.4. xy _ z _ xxyx _ px _ yxzpx _ yxzpx

1. xpzxx

2. yxyzx

3. yxzpx

4. zyxpy

Sol : Option 1

The series is xyxzpx/xyxzpx/xyxzpx/xyxzpx. Thus, the pattern ‘ xyxzpx’ is repeated.

Q.5. WYB, XUD, YQF, …

1. HZM

2. HCZ

3. ZMH

4. None of these

Sol : Option 3

Divide each member of series in this way: B D F H and so on (one gap) in ascending order, Y U Q M and so on (three gap) in descending order, WX Y Z and so on (no gap) in ascending order

Q.6. x_ p _ y _ _ pzy _ _ pzy

1. xyyyzz

2. xyzyzy

3. yxzyxy

4. yzxyxy

Sol : Option 4

The series is xypzy/ xypzy/ xypzy. Thus, the pattern ‘ xypzy’ is repeated.

Q.7. SAB, ?, QCD, PDD, OEF, NFF

1. CBT

2. ABR

3. BCT

4. RBB

Sol : Option 4

First letter in every group is in reverse alphabetical order i.e. SRQPON. The middle letter is in alphabetical order i.e ABCDEF and the last letter has pairs, BB, DD & FF.

Q8. _ x _ y _ xyxx _ yxy _ xyyx

1. xxxyy

2. xyxyy

3. yxyxy

4. yxyyx

Sol : Option 4

The series is yxx/yyx/ yxx/yyx/ yxx/yyx. Thus, the pattern yxx/yyx is repeated.

Q9.BAZ, DBY, FCX, ?

1. FXW

2. EFX

3. FEY

4. HDW

Sol : Option 4

The third, sixth and ninth letters are in the reverse order of the alphabet i.e.Z,Y, X, W. Ist fourth and seventh letters are going up with a gap of one letter and II, V and VIIIth are moved ahead one letter.

Q. 10 _ yz _ zx _ xyx _ z _ zxzxy

1. xyzyy

2. yyyzz

3. yxzyx

4. xyyzz

Sol : Option 1

The series is xyz/yzx/zxy /xyz/yzx/zxy . So, the letters change places in a cyclic manner.

Q1. a b _ b b c _ c _ a b _ a b _ b

(a) ccaac

(b) cbabc

(c) cacac

(d) bccab

Ans.(c)

Sol. The series is abc/b/bca/c/cab/a/abc/b.

Q2. _ a _ b _ a b a a _ b a b _ a b b

(a) aaabb

(b) ababb

(c) babab

(d) babba

S2. Ans.(d)

Sol. The series is baa/bba/baa/bba/baa/bb.

Thus, the pattern baa/bba is repeated.

Q3. c _ b a a _ a c a _ c a c a b _ a c a c _ b c a

(a) acbaa

(b) bbcaa

(c) bccab

(d) cbaac

S3. Ans.(a)

Sol. The series is cab/aa/cacab/cacab/aa/cacab/ca.

Thus, the pattern â€˜cacab/cacab/aaâ€™ is repeated.
