Question

In the following letter series, some of the letters are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

$\text{abca _ bcaab _ aa _ caa _ c}$

• A. $\text{bbac}$
• B. $\text{bbaa}$
• C. $\text{acbb}$
• D. $\text{acac}$ 

Answer 1

Given that, $abca \_ bcaab \_ aa \_ caa \_ c$

We can make the pattern, like this,

$abca \mid \_ bca\mid ab \_ a \mid a \_ ca \mid a \_ c$

Now, we can fill the blank,

$abca \mid {\color{Red}a} bca\mid ab {\color{Blue}c } a \mid a {\color{Orange} b} ca \mid a {\color{Magenta} b} c$

So, the correct answer is $(C).$
