Answer:
(3) 37 : 50
Step-by-step explanation:
The number pairs in options (1), (2), and (4) follow a pattern where the second number is 17 more than the first number. For example, in option (1), 65 + 17 = 82, in option (2), 145 + 17 = 162, and in option (4), 120 + 17 = 137. However, option (3) does not follow this pattern as 37 + 17 is not equal to 50. Therefore, option (3) is different from the others.
Answer:
The pattern followed here is:
1. 14, 12 → 14 × 12 = 168
2. 24, 7 → 24 × 7 = 168
3. 37, 4 → 37 × 4 = 148
4. 42, 4 → 42 × 4 = 168
The product of all options except ’37, 4’ is 168.
Hence, ’37, 4’ is the odd one out.
