#### Answer:

10! is the answer.

#### Explanation:

this is just like you are given 10 lines on a paper and you have to arrange 10 names on those 10 lines in all different ways .
so , starting with the lowermost line, you can put one of 10 names on that line and then on the line above that you can put 1 of 9 names and so on .
so the total ways to arrange all the names on those lines in all ways will be : $10 \cdot 9 \cdot 8 \cdot 7 \cdot 6 \cdot 5 \cdot 4 \cdot 3 \cdot 2 \cdot 1$ = 10!
