Solutions: ( 1 to 10 )

When we sequentially fill “cacc” in the gaps we get
a c ca a ca c caa c
When we split the sequence as three parts, we get acca , acac and caac.
The first term and the last term have the same first and last letters while the middle term has alternate letters thus forming a pattern.
Hence Option B is the correct answer.

The pattern is that we need to write ‘xyz’ followed by ‘aa’ and then need to write it in reverse.
=> xyz aa zyx xyz aa zyx
=> Ans – (C)

The pattern followed is that, in a group of three letters, two alternate words ‘lub’ and ‘tub’ are written.
=> lub tub lub tub lub tub
=> Ans – (B) : utlub

Upon placing the option ‘bbaa’ into the blanks, we have: baababbabaababba
Clearly, the pattern ‘baababba’ repeats .
baababba | baababba
Option A is the correct answer.

abba: aaabaabaaabbaaba
abab: aaabaabaaaababba
abaa : aaabaabaaaabaaba
Clearly, the pattern ‘aabaabaa’ repeats here.a | aabaabaa | aabaaba
babb: aabbaaaaaabbabba
Option C is the correct answer.

here in this question every term is AZBY
so the given pattern is AZB_, AZ _Y, A _BY, _ ZBY
in order to fulfill this we need to fill ” YBZA” from left to right in the blanks ..

Expression : adb _ ac _ da_cddcb _ dbc _ cbda
The pattern is that in a group of 4 letters, there is a combination of first four alphabets, i.e. ‘a,b,c,d’.
=> adbc acbd abcd dcba dbca cbda
=> Ans – (C)

Expression : a_ _b abba_abb a_ba
The pattern is that in a group of 4 letters, the combination of 2 a’s and 2 b’s are used.
=> aabb abba aabb abba
=> Ans – (A)
