Question

In the following questions, a letter series is given, in which some letters are missing. The missing letters are given in the proper sequence as one of the alternative. Find the correct alternative.

$C....BBB....ABBBB....ABBB.....$

• A. $BACBB$
• B. $AABCB$
• C. $ABACB$
• D. $ABCCB$
• E. $ABBCC$

Answer 1

The correct option is D $ABCCB$

We would now analytically observe the series to get some conclusions.

$\left(1\right)$ The no. of 'B's together are greater than or equal to 4

$\left(2\right)$ 'A' comes before the Bs. (Find out why it can't come after the Bs)

$\left(3\right)$ 'C' must have a bridge between itself and the Bs.

These results show that the repeating unit must be $CABBBB$

Thus the answer is $ABCCB$ which is $\left(D\right)$
