Answer: 2345, 3425, and 8435
In simple words: The digit at the tens place in 2345, 3425, and 8435 is 4.

Q2. MAKE LARGEST AND SMALLEST FOUR DIGIT NUMBERS WITH GIVEN DIGITS
7, 8, 0, 5
6, 8, 1, 3
Answer:
For 7, 8, 0, 5: Largest = 8750, Smallest = 5078
For 6, 8, 1, 3: Largest = 8631, Smallest = 1368
In simple words: To make the largest number, arrange digits in descending order. To make the smallest number, arrange digits in ascending order without putting 0 at the first place.
