IBPS PO Reasoning: Alphabetical Reasoning questions with solutions

Q1. In the word DANGEROUS, if all the vowels are replaced by the next letter and all the consonants are replaced by the previous letter, then all repeated letters are removed, how many letters lie between the 6th letter from the left and the 4th letter from the right according to alphabetical order?

1. 7
2. 4
3. 2
4. 1

Answer: 4

After shifting vowels to the next letter and consonants to the previous letter, the word becomes a new sequence with repeated letters removed. Identifying the 6th letter from the left and the 4th from the right in that final sequence gives two letters whose alphabetical positions differ by 5, so there are 4 letters between them.

Q2. If the vowels are arranged in alphabetical increasing order from left to right and then the consonants are arranged in alphabetical increasing order from left to right in the word ALONGSIDE, which letter is 4th from the left in the new word?

1. A
2. I
3. S
4. O

Answer: O

The word ALONGSIDE has vowels A, O, I, E and consonants L, N, G, S, D. Arranging vowels in increasing order gives A, E, I, O and consonants in increasing order gives D, G, L, N, S. The new word becomes AEIODGLNS, so the 4th letter from the left is O.
