In each of the following questions, choose the number - letter group which is different from the others.

Options

A. M5S
B. B9L
C. T4Y
D. F4J

Answer

To solve the question, we need to analyze the given groups of letters and numbers to identify which one is different from the others based on a specific pattern. Let's break it down step by step.

### Step 1: Identify the Groups
We have four groups to analyze:
1. M5S
2. B9L
3. T4Y
4. F4Y

### Step 2: Convert Letters to Numbers
Using the position of letters in the alphabet:
- M = 13
- B = 2
- T = 20
- F = 6

Now, let's rewrite the groups with their corresponding letter values:
1. M5S → (13, 5, S)
2. B9L → (2, 9, L)
3. T4Y → (20, 4, Y)
4. F4Y → (6, 4, Y)

Next, we convert the letters S, L, and Y to their respective positions:
- S = 19
- L = 12
- Y = 25

Now we have:
1. M5S → (13, 5, 19)
2. B9L → (2, 9, 12)
3. T4Y → (20, 4, 25)
4. F4Y → (6, 4, 25)

### Step 3: Check the Patterns
Now, we will check if there is a pattern in the sums of the numbers in each group.

For each group, we will calculate:
- Group 1: 13 + 5 = 18, and 18 + 1 = 19 (matches S)
- Group 2: 2 + 9 = 11, and 11 + 1 = 12 (matches L)
- Group 3: 20 + 4 = 24, and 24 + 1 = 25 (matches Y)
- Group 4: 6 + 4 = 10, and 10 + 1 = 11 (does not match Y)

### Step 4: Identify the Odd One Out
From the calculations:
- Groups 1, 2, and 3 follow the pattern where the sum of the first two numbers plus one equals the third number.
- Group 4 does not follow this pattern.

### Conclusion
Thus, the group that is different from the others is **F4Y**.
