If 1005x4 is divisible by 8, find the value of x?

### Solution

If the number formed by last three digits is divisible by 8, then the entire number is divisible by 8.

Start trying from 504, 514, and so on

We obtain 504, 544 and 584 as the possibilities.

Depending on the options, x = 0, 4, 8 ans!
