Question

In each of the following questions, four options have been given, out of which three are alike in some manner and the fourth one is different. Choose out the odd one.
1. CBUV
2. YXTU
3. RQOP
4. IJSO

Answer 1

Correct Answer - Option 4 : IJSO

​​The logic follows here is:-

Place value of first letter - 1 = Second letter, Place value of third letter + 1 = Fourth letter

Let's check each option:-

1) C - 1 = B, U + 1 = V

2) Y - 1 = X, T + 1 = U

3) R - 1 = Q, O + 1 = P

4) I - 1 = H ≠ J, S + 1 = T ≠ O

Hence, 'IJSO' is odd one among given alternatives.
