There are two letters in the word ‘SCIENTIFIC’ such that the number of letters between them is the same as the number of letters between them in the alphabet. The letter which comes later in the alphabet is your answer. If no such pair of letters is possible, then your answer is ‘X’. (a) E (b) C (c) I (d)X

latest answer

In the word SCIENTIFIC, between C and E, there is only 1 letter - "I". Also, in the alphabetical order, between C and E, there is only 1 letter - "D". So, in this pair of C and E, the later alphabet is E. So, E is the right answer.
