If 3 is added to each odd digit and 1 is subtracted from each even digit in the number 42514563. What will be the difference between the highest and lowest digits thus formed?

Explanation

Solution: Let's go through each digit in the number 42514563 and apply the given conditions: 4 (even) → 4 - 1 = 3 2 (even) → 2 - 1 = 1 5 (odd) → 5 + 3 = 8 1 (odd) → 1 + 3 = 4 4 (even) → 4 - 1 = 3 5 (odd) → 5 + 3 = 8 6 (even) → 6 - 1 = 5 3 (odd) → 3 + 3 = 6 After applying the transformations, the new number formed is 31843856. Step 2: Identify the highest and lowest digits in the new number The highest digit is 8. The lowest digit is 1. Step 3: Calculate the difference Difference = Highest digit - Lowest digit = 8 - 1 = 7 Answer: The difference between the highest and lowest digits thus formed is 7.
