Answer 1

Answer:

Here as the number is lying between 4000 and 5000, we can conclude that the number is of 4-digits and the number must be starting with 4.

Now, for a number to be divisible by 5 must ends with 5

Let us represent the 4-digit number

Therefore,

The first place is occupied by 4 = 1 way

The fourth (last) place is occupied by 5 = 1

way

The second place can be filled by 5

numbers = 5 ways

Total numbers formed = 1 x 5 x 5 x 1= 25
