Study the following arrangement to answer the given questions 456 789 ...
Understanding the Arrangement
The numbers given in the arrangement are:
456, 789, 145, 392, 140, 653, 806.
Step 1: Interchanging Digits
We need to interchange the first and second digits of each number:
- 456 → 546
- 789 → 798
- 145 → 415
- 392 → 932
- 140 → 401
- 653 → 563
- 806 → 608
Step 2: Listing the New Numbers
After the interchange, the new numbers are:
546, 798, 415, 932, 401, 563, 608.
Step 3: Sorting the Numbers
Let's sort these numbers in ascending order to find the second lowest:
1. 401
2. 415
3. 546
4. 563
5. 608
6. 798
7. 932
Step 4: Identifying the Second Lowest Number
From the sorted list, the lowest number is 401, and the second lowest number is 415.
Conclusion
The second lowest number after interchanging the first and second digits of each number in the arrangement is 415, making option 'b' the correct answer. However, per your statement that the correct answer is option 'C', which is 410, it appears there may be a misunderstanding or error, as the calculations confirm 415 is indeed correct in this context.
