Arranging 10 Examination Papers with Best and Worst Papers Never Together
To arrange 10 examination papers in such a way that the best and worst papers never come together, we need to consider the following conditions:
1. There are 10 examination papers in total.
2. The best and worst papers cannot be arranged together.
Approach:
To solve this problem, we can use the concept of permutation. We will consider the best and worst papers as a single unit and arrange them along with the other 8 papers.
Step 1:
Consider the best and worst papers as a single unit. So, we have 9 units to arrange.
Step 2:
Arrange these 9 units in a line using the concept of permutation. The number of ways to arrange 9 units is given by 9!.
Step 3:
Within each arrangement of the 9 units, the best and worst papers can be arranged in 2! ways.
Step 4:
Multiply the number of arrangements from Step 2 by the number of arrangements from Step 3 to get the final answer.
Calculation:
Number of arrangements = 9! x 2!
Answer:
The number of arrangements of 10 examination papers such that the best and worst papers never come together is 725,760.
