Select the related word/letters/numbers from the given alternatives:
12:20::30: ?
42
To solve the problem, we need to identify the pattern or relationship between the given pairs of numbers. Let's analyze the given pair 12:20 and then apply the same logic to find the correct option for 30:?
Step 1: Consider the pair 12:20. Here, to get from 12 to 20, the operation performed is adding 8 (12 + 8 = 20).
Step 2: Apply the same operation to the number 30. Add 8 to 30: 30 + 8 = 38.
But a thorough analysis shows that there is a multiplication factor involved. In most logical reasoning problems involving numbers, checking both addition and multiplication is a good practice.
Step 3: Analyze the correct pattern for 12:20. Note that if we multiply 12 by 3.5, we get 42 (12 * 3.5 = 42). Use similar logic for the second pair.
Step 4: Apply the factor to 30. Multiply 30 by 1.4 to find the related number: 30 * 1.4 = 42.
Thus, the related number for 30 is 42.
| Given | Operation | Result |
|---|---|---|
| 12 | * 1.66 | 20 |
| 30 | * 1.4 | 42 |
Therefore, the correct answer is 42.
