Let the days required by Ajay to complete the work be (x+5), then days required by Vijay are x.
Let the total work be w.
Then,
Ajay's one day work =

Vijay's one day work =

The total work done by them in one day=

Their work done in 4 days =

This is the work done by them in 4 days. Now Vijay has left and only Ajay is left to work.
Remaining work which only Ajay has to do:

Now this is the work Ajay Does in 5 days.
Days taken by Ajay = Remaining work / Work done in 1 day.
Therefore,

Since x is the number of days.

The days required by Vijay to complete the work are 10.
The days required by Ajay to complete the work are (x+5) = 15.
Done.
