Explanation:

Let’s break this down step by step, just like you’d work a logic puzzle with a friend:

- First, let’s figure out the pattern from the example:

- Step I: Orders numbers in ascending order.

- Step II: Arranges the digits of each number in ascending order.

- Step III: Adds up the first two digits, then the next two.

- Step IV: Sums up the two numbers from Step III for each item.

- Step V: Sorts the numbers from Step IV in descending order.

Now, let’s run your set—6482, 5113, 9438, 2799, 6619, 4431— through these rules.

Step 1: Order ascending

4431 5113 6482 6619 2799 9438

Step 2: Each number’s digits ascending

1344 1135 2468 1669 2799 3489

Step 3: Add first two digits, then last two

1+3=4 1+1=2 2+4=6 1+6=7 2+7=9 3+4=7

4+4=8 3+5=8 6+8=14 6+9=15 9+9=18 8+9=17

So,

4 8

2 8

6 14

7 15

9 18

7 17

Step 4: Add sums from Step 3 for each number

4+8=12

2+8=10

6+14=20

7+15=22

9+18=27

7+17=24

So your Step IV is:

12 10 20 22 27 24

Largest: 27, Smallest: 10

Sum: 27 + 10 = 37

Now, your given answer was option 2: 88

- Option 1: 82

- Option 2: 88

- Option 3: 102

- Option 4: 84

- Option 5: 40

So, the real correct sum is 37 (not among the options, so the answer would be none of the above if that were a choice, but asked to pick the sum, not a closest or correct option).

Here’s what you actually need to know:

- The logic is to break down each core operation, not skip straight to expected sums.

- Always re-calculate each step, or you’ll trip on these rearrangement puzzles.

That’s how you approach it—clear and careful, step by step.
