1.	Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the number-pair that is different.1. 21 ∶ 1392. 25 ∶ 1673. 15 ∶ 1974. 27 ∶ 181
Answer» Correct Answer - Option 3 : 15 ∶ 197 The logic is: 1st number × 7 - 8 = second number 1. 21 ∶ 139 → 21 × 7 - 8 = 147 - 8 = 139 2. 25 : 167 → 25 × 7 - 8 = 175 - 8 = 167 3. 15 : 197 → 15 × 7 - 8 = 105 - 8 = 97 ≠ 197 4. 27 : 181 → 27 × 7 - 8 = 189 - 8 = 181 Except option 3, all options are follow the given logic. thus option 3 is an odd one. Hence, ‘15 : 197’ is the odd one out.

Answer» Correct Answer - Option 3 : 15 ∶ 197

The logic is:

1st number × 7 - 8 = second number

1. 21 ∶ 139 → 21 × 7 - 8 = 147 - 8 = 139

2. 25 : 167 → 25 × 7 - 8 = 175 - 8 = 167

3. 15 : 197 → 15 × 7 - 8 = 105 - 8 = 97 ≠ 197

4. 27 : 181 → 27 × 7 - 8 = 189 - 8 = 181

Except option 3, all options are follow the given logic. thus option 3 is an odd one.

Hence, ‘15 : 197’ is the odd one out.
