it is given that first digit can't be 4
Also first digit can't be 0, if it becomes 0 number will become of 4 digits.
1. Condition of divisibility by 5
Last digit can be 0 only because no must be divisible by 5
2. Condition of divisibility by 8
Last 3 digits must be either divisible by 5 or must be 0
3. Condition of divisibility by 11

Applying all the three conditions we get the no 11000.
