For this problem, here’s how you do it.
Answer:
702
Step-by-step explanation:
The total number of Fish in the aquarium is got by adding up the
Number of Salt Water Fish, and
Number of Fresh water Fish
Number of Salt water Fish = 483
Number of Fres hwater Fish = 358
Total Fish in Aquarium = 483 + 358 = 841
Later, 139 were moved to a new aquarium, the number of fish remaining is 841 MINUS 139. That is:
841 - 139 = 702 fish remaining now

52/13 = 4
91/13 = 7

There are 20! number of ways for everyone to do this so that at the end of the move, each seat is taken by exactly one person.
People are seated in a 2 by 10 rectangle grid. All 20 persons stand up from their seats and relocate to an orthogonally neighboring one upon the blowing of a whistle.
Now, we have to find the number of possible ways in which each seat is taken up by exactly one person after the move.
As the number of people is 20 and 20 seats are to filled exactly once.
So, the number of ways = 20!
