Consider the set of three-digit numbers: 216, 352, 702, 853, and 952. If all three digits of each number are arranged in ascending order within the number, which of the original numbers will result in the second highest value?

Given the numbers 216, 352, 702, 853, and 952, if the first and third digits of each number are interchanged, how many of the resulting numbers will be odd numbers?

Among the set of three-digit numbers {216, 352, 702, 853, 952}, if 157 is added to the smallest number (216) and 175 is subtracted from the largest number (952), what will be the sum of the first digit of the result obtained from the smallest number and the third digit of the result obtained from the largest number?
