Q1. Consider the following sequence that follows some arrangement: c_accaa_aa_bc_b The letters that appear in the gaps are [CSAT 2019]

(a) abba

(b) cbbb

(c) bbbb

(d) cccc

Solution:

Given that,

c_accaa_aa_bc_b

Thus by the options the correct sequence is

c c a c c /a a b a a /b b c b b

Hence option (b) is correct

Q2. Consider the following arrangement that as some missing letters: abab_b_bcb_dcdcded_d the missing letters which complete the arrangement are [CSAT 2020]

(a) a, b, c, d

(b) a, b, d, e

(c) a, c, c, e

(d) b, c, d, e

Solution:

Given that,

abab_b_bcb_dcdcded_d

Thus by the options the correct sequence is

a b a b a/ b c b c b/ c d c d c/ d e d e d

Hence option (c) is correct

Q3. In the series _b_a_ba_b_abab_aab; fill in the six blanks (_) using one of the following given four choices such that the series follows a specific order. [CSAT 2021]

(a) bababa

(b) baabba

(c) bbaabb

(d) ababab

Solution:

Given that,

_b_a_ba_b_abab_aab

Thus by the options the correct sequence is

a b b a a b/ a b b a a b/ a b b a a b

Hence option (d) is correct

Q4. Consider the sequence

ABC_ _ABC_DABBCD_ABCD that follows a certain pattern. Which one of the following completes the sequence? [CSAT 2023]

(a) DACB

(b) CDAB

(c) DCCA

(d) DDCA

Solution:

Given that,

ABC__ABC_DABBCD_ABCD

Thus by the options the correct sequence is

A B C D D/ A B C C D/ A B B C D /A A B C D

Hence option (d) is correct

Q5. Consider the sequence A_BCD_BBCDABC_DABC_D that follows a certain pattern. Which one of the following completes the sequence? [CSAT 2024]

(a) B, A, D, C

(b) B, A, C, D

(c) A, A, C, D

(d) A, A, D, C

Solution:

Given that,

A _ BCD _ BBCDABC _ DABC _ D

Now,

AABCD|ABBCD| ABCCD|ABCDD

Thus the blank follows AACD

Hence option (c) is correct
