Study the following arrangement to answer the given questions 915 678 ...
To find the sum of the second lowest number, we need to add 1 to the first digit of the even numbers and subtract 1 from the first digit of the odd numbers in the given arrangement.
Given arrangement: 915 678 435 768 123 576
Step 1: Add 1 to the first digit of the even numbers
- The even numbers in the arrangement are 678, 768, and 576.
- Adding 1 to the first digit of each even number, we get 778, 868, and 676.
Step 2: Subtract 1 from the first digit of the odd numbers
- The odd numbers in the arrangement are 915, 435, and 123.
- Subtracting 1 from the first digit of each odd number, we get 815, 335, and 023.
Step 3: Arrange the modified numbers in ascending order
- The modified numbers are 778, 868, 676, 815, 335, and 023.
- Arranging these numbers in ascending order, we get 023, 335, 676, 778, 815, and 868.
Step 4: Find the second lowest number
- The second lowest number in the arranged sequence is 335.
Step 5: Find the sum of the second lowest number
- The sum of the digits in the second lowest number (335) is 3 + 3 + 5 = 11.
Therefore, the sum of the second lowest number is 11.
Hence, the correct answer is option D) 17.
