Question 483262
Numbers between 4000 an 5000  would start with 4 and will have 4 digits.

So the first position will be filled by 4 and the number would look like

4 _ _ _

Then the remaining 3 digits will be formed from remaining 5 digit 2,3,5,6,7 in 5P3 ways (no repeatitions).

Numbers formed = 1. 5P3 
= 5!/(5-3)!
= 5*4*3
= 60

In order for these numbers to be divisible by 5, the number would be 
4 - - 5

And the number would be formed by filling up 2nd and 3rd digit from the remaining 4 digits 2,3,6,7 in 4P2 ways i.e 4*3 = 12
