Logical Reasoning(IBPS CL) Input-Output

Directions : Study the following information carefully to answer the given questions:

A word and number arrangement machine when given an input line of words and numbers rearranges them following a particular rule. The following is an illustration of input and rearrangement.

INPUT—2538 5628 8516 7524 6325 2645

STEP I- 2358 2568 1568 2457 2356 2456

STEP II- 1568 2356 2358 2456 2457 2568

STEP III- 56 35 35 45 45 56 STEP IV- 11 8 8 9 9 11

Step IV is the last step of the rearrangement.

As per the rules followed in the above steps, find out in each of the following questions the appropriate steps for the given input.

Input: 3846 9213 8273 7341 5218 3285 6925 4758

Explanation:

Let’s really walk through this, step by step. The pattern in the given example is key, so let’s make sure we crack it before checking the final sums.

Here’s what we see in the sample sequence:

- Step I: Rearranged each four-digit number into ascending order of digits.

- Example: 2538 ? 2358

- Step II: Arrange the whole row of numbers (from Step I) in ascending order.

- So all those four-digit numbers are sorted from smallest to largest.

- Step III: For each four-digit number, add up the first two digits and then the last two.

- So, 1568 ? 1+5=6 and 6+8=14 (but the example shows “56,” which means, it just takes the middle digits. But let’s look closer...)

- Actually, on second thought — in the sample, 1568 becomes 56, so they’re just pulling out the middle two digits for each number. Confirmed by more examples there.

- Step IV: Now, with the two-digit values from Step III, add their individual digits.

- So, 56 ? 5+6=11, 35 ? 3+5=8.

So, input your numbers into the process:

Your input:

3846, 9213, 8273, 7341, 5218, 3285, 6925, 4758

# Step I (arrange digits in ascending order):

- 3846 ? 3468

- 9213 ? 1239

- 8273 ? 2378

- 7341 ? 1347

- 5218 ? 1258

- 3285 ? 2358
