10 >>In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

a _ bc _ c _ abb _ bca _ ?

• (A) cccbc
• (B) cbbac
• (C) accba
• (D) abbba

Solution The series is a'a' / b / c'c'c'c' / a / bb'b'b / c / a'a'.

11 >>In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

_ c _ bd _ cdcda _ a _ db _ a ?

• (A) adabcd
• (B) cdbbca
• (C) daabbc
• (D) bdbcba

Solution The series is 'a'c'd'b / d'a'cb / cda'b' / a'c'db / 'd'a. The third letter in each sequence becomes the first letter in the following sequence.

12 >>In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

a _ bc _ a _ bcda _ ccd _ bcd _ ?

• (A) adbcab
• (B) adbbad
• (C) acbdbb
• (D) abddbd

Solution The series is a'a'bc'd' / a'b'bcd / a'b'ccd / 'a'bcd'd'. Thus, a, b, c and d are repeated twice one by one.

13 >>In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

_ cb _ ca _ bacb _ ca _ bac _ d ?

• (A) bddddb
• (B) bbbddd
• (C) addddb
• (D) addbbb

Solution The series is 'a'cb'd' / ca'd'b / acb'd' / ca'd'b / ac'b'd. Thus, the pattern acbd / cadb is repeated.

14 >>In following questions, three sequence of alphabets/numerals are provided which correspond to each other in some way. Find out alphabets/numerals that come in the blank places.Choose the correct optionC

CB _ _ D _ B A B C C B _ _ 1 2 4 3 _ _ ? ? ? ? a _ a b _ c _ b _ _ _ _ ?

• (A) 3, 4, 4, 3
• (B) 3, 2, 2, 3
• (C) 3, 1, 1, 3
• (D) 1, 4, 4, 1

Solution Comparing position of capital letters, numbers and small letters, as we find: a correspondes to C and 1 corresponds to a. So a and 1 corresponds to C. b corresponds to A and 2 corresponds to b. So b and 2 corresponds to A. Also, 4 corresponds to D. So the remaining number i.e. 3 corresponds to B, So BCCB corresponds to 3, 1, 1, 3.

15 >>In following questions, three sequence of alphabets/numerals are provided which correspond to each other in some way. Find out alphabets/numerals that come in the blank places.Choose the correct option.

_ A C _ B D _ C D C D 2 _ 4 1 _ 1 4 _ _ _ _ c d _ b c _ a ? ? ? ? ?

• (A) a, b ,a ,b
• (B) a, c, a, c
• (C) c, b, c, b
• (D) c, d, c, d

Solution Clearly, 4 corresponds to C and a corresponds to 4. So, a corresponds to C. 1 corresponds to D and b corresponds to 1. So, b corresponds to D. Thus, CDCD corresponds to a, b, a, b.

16 >>In following questions, three sequence of alphabets/numerals are provided which correspond to each other in some way. Find out alphabets/numerals that come in the blank places.Choose the correct option

A _ B A C _ D _ B C D C _ 3 _ 2 _ 1 _ 4 ? ? ? ? d c _ _ b a c b _ _ _ _ ?

• (A) 1, 3, 4, 3,
• (B) 1, 4, 3, 4
• (C) 2, 3, 4, 3
• (D) 3, 4, 1, 4

Solution Clearly, 2 corresponds to A. Now, b corresponds to C and 4 corresponds to b. So, 4 corresponds to C. c corresponds to D and 3 corresponds to c. So, 3 corresponds to D. So, the reamaining number   i.e.,  1 corresponds to B. Thus, BCDC corresponds to 1, 4, 3, 4.

17 >>In following questions, three sequence of alphabets/numerals are provided which correspond to each other in some way. Find out alphabets/numerals that come in the blank places.Choose the correct option.

_ A D A C B _ _ B D C C 1 3 _ _ 1 2 4 2 _ _ _ _ a _ _ b _ _ c d ? ? ? ? ?

• (A) a, c, d, d
• (B) a, d, c, c
• (C) c, a, d, d
• (D) d, c, a, a

Solution Clearly, b corresponds to A. 1 corresponds to C and a corresponds to 1. So, a corresponds to C. 2 corresponds to B and d corresponds to 2. So, d corresponds to B. So, the remaining lettter  i.e., c corresponds to D. Thus, BDCC corresponds  to d, c, a, a.

18 >>Find the alternative number for the question mark in the given series?

1, 9, 25, 49, ?, 121 ?

• (A) 64
• (B) 81
• (C) 91
• (D) 100

Solution The given series consists of squares of consecutive odd numbers. So missing term = 81.

19 >>Find the alternative number for the question mark in the given series?

4, 7, 12, 19, 28, ? ?

• (A) 30
• (B) 36
• (C) 39
• (D) 49

Solution The pattern is 3, 5, 7, 9,..... So missing term = 11 => 28+11 = 39.

20 >>Find the alternative number for the question mark in the given series?

11, 13, 17, 19, 23, 25, ? ?

• (A) 26
• (B) 27
• (C) 29
• (D) 37

Solution The pattern is 2, 4, 2, 4,..... So missing term = 25 + 4 = 29.
