Question

How many 4-digit numbers divisible by 5, all of the digits of which are even, are there?

Answer 1

There are a total of 100 numbers!!

Explanation:

Basically you have to do

4*5*5*1 because there are 4 even numbers 2,4,6,8 that can be in the beginning of a number, 5 even numbers 0,2,4,6,8 that can be in the middle and only 1 number at the end that will make it divisible by 5 which is zero.

Hope this helps!!!
