1. Which one set of letters when sequentially placed at the gaps in the given letter series shall complete it ?

m _ nm _ n _ an _ a _ ma _

a) aamnan

b) ammanm

c) aammnn

d) amammn

Explanation: The series is m

__a__n/m

__a__n/

__m__an/

__m__a

__n__/ma

__n__. Thus, the pattern 'man' is repeated.

2. Which one set of letters when sequentially placed at the gaps in the given letter series shall complete it ?

_bcc _ ac _ aabb _ ab _ cc

a) aabca

b) abaca

c) bacab

d) bcaca

Explanation: The series is

__b__bcc

__a__a/c

__c__aabb/

__a__ab

__b__cc. Thus, the letter pairs move in a cyclic order..

3.Which one set of letters when sequentially placed at the gaps in the given letter series shall complete it ?

_ op _ mo _ n _ _ pnmop _.

a) mnpmon

b) mpnmop

c) mnompn

d) mnpomn

Explanation: The series is

__m__op

__n__/mo

__p__n/

__mo__pn/mop

__n__. Thus, the pattern 'mopn' is repeated.

4. Choose the correct order of the given alternative : _ _ aba _ _ ba _ ab

a) abbba

b) abbab

c) baabb

d) bbaba

Explanation: The series is

**a**

**b**/ab/a

**b**/

**a**b/a

**b**/ab. Thus the pattern 'ab' is repeated..

5. Choose the correct order of the given alternative : ab _ _ baa _ _ ab _

a) aaaaa

b) aabaa

c) aabab

d) baabb

Explanation: The series is ab

**a**/

**a**ba/a

**b**

**a**/ab

**a**. Thus, the pattern 'aba' is repeated.

6. Choose the correct order of the given alternative : _ acca _ ccca _ acccc _ aaa

a) acca

b) caaa

c) ccaa

d) caac

Explanation: The series is

**c**a/cca

**a**/ccca

**a**a/cccc

**a**aaa..

7. Choose the correct order of the given alternative : a _ cacbc _ baca _ _ b

a) baba

b) babc

c) abac

d) cacb

Explanation: The series is a

**b**cac/bc

**a**ba/ca

**bc**b. Thus, the series consists of three sequences. The first three letters of each sequence are in a cyclic order and the last two letters of each sequence are the same as the first and third letters of the sequence.

8. Choose the correct order of the given alternative : aab _ ab _ cabcca _ bcab _ c

a) bbbc

b) bbab

c) cabc

d) cbab

Explanation:The series is aa/b

**c**ab/

**b**cab/cca

**a**/bcab/

**b**c. Thus, the pattern 'ccaa' followed by 'bcab' repeated twice, makes up the series..

9. Choose the correct order of the given alternative : a _ ca _ bc _ bcc _ bca

a) bbaa

b) bbab

c) aabb

d) baba

Explanation: The series is a

**b**ca

**b**/bc

**a**bc/c

**a**bca.

10. Choose the correct order of the given alternative : c _ ac _ aa _ aa _ bc _ bcc

a) cabba

b) ccbbb

c) bbbbb

d) cbacb

Explanation: The series is c

**c**ac

**c**/aa

**b**aa/

**b**bc

**b**b/cc.
