Question

aab....aaa......bba.....

• A. baa
• B. abb
• C. bab
• D. bbb

Answer 1

The correct option is A baa

1 First blank space should be filled in by 'b' so that we have two a's followed by two b's
2 Second blank space should be filled in either by 'a' so that we have four a's followed by two b's or by 'b' so that we have three a's followed by three b's
3 Last space must be filled in by 'a'
4 Thus we have two possible answer : 'baa' and 'bba' But only 'baa' appears in the alternatives So the answer is (a).
5 In case we had both the possible answer in the alternatives we would have chosen the one that forms a more prominent pattern which is aabb/aaabbb/aa Thus our answer would have been "bba"
