To solve this question, we make use of the following formula
The above formula implies that;
On a single path, there is a total of m + n steps to get to a particular position, where each path is either in m direction or n direction.
In this case:
So, we have:
Apply combination formula
Expand the numerator
Expand the denominator
<em>Hence, there are 84 possible paths</em>
<em></em><em> will also give the same result</em>
The time taken to fill the tank using a pump that pumps 25L per minute
is 30.4 minutes
Given that A 1000L tank now contains 240L of water and asked the time taken to fill the tank using a pump that pumps 25L per minute.
The amount of water that can be filled in tank=760L
Given that a pump that pumps 25L per minute ,
The time required to fill 760L {if a pump that pumps 25L per minute }=
The time required to fill 760L {if a pump that pumps 25L per minute }=30.4 minutes
Therefore,The time taken to fill the tank using a pump that pumps 25L per minute is 30.4 minutes
