If 2 + 3 = 13, 3 + 4 = 25, then 4 + 5 = ?
Correct answer: C. 41
- A. 30
- B. 37
- C. 41
- D. 45
Explanation
The pattern requires you to first add the two numbers, then add the product of the two numbers to the sum. In the case of 4 + 5, you first calculate the sum: 4 + 5 = 9. Next, multiply the two numbers: 4 × 5 = 20. Finally, add these results together: 9 + 20 = 41. Hence, the correct answer is 41. Option A (30), Option B (37), and Option D (45) do not follow this pattern, leading to incorrect results.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
