Question

Consider the following sequence that follows some arrangement:
c_accaa_aa_bc_b
The letters that appear in the gaps are

(A)abba
(B)cbbb
(C)bbbb
(D)cccc​

Answer 1

Answer:

Combination of two letters are seen in this pattern ie: aa,bb,cc.

Step 1 : Finding out the pattern a,b,c within the two combination of patterns as mentioned above.

Step 2 : patterns are in the following sequence cc,aa,?? - whcih is the remaining two combination letter bb.

Step 3: placing a,b,c pattern in the middle of two letter combinations cc,aa,bb

step 4: The Answer is B - cCaccaaBaaBbcBb

ie: ccAcc - aaBaa - bbCbb.

Step-by-step explanation:

Answer 2

Answer:

cbbb

Step-by-step explanation:

→Find out no of digits in give pattern; divide them in group of three, four or five depending upon no. of digits.

Here, no of digits is 15; so we divide it in 5 group of 3-3 digits (Case-I) OR in 3 groups of each having 5-5 digits(Case-II).

→Next step is to identify the pattern,

In this given problem it is pretty easy to see that Case-II holds true with pattern having:

c_acc/aa_aa/_bc_b

→The ordering of abc in middle of each parts is in anti clockwise direction:

c⇒a⇒b⇒c.

→Identify the remaining pattern and fill blanks on the basis of same pattern on which others groups of corresponding digits are filled

This gives,

ccacc/aabaa/bbcbb

Hence, cbbb is answer.
