If n is a positive integer, what is the value of the hundreds digit of 30n?
1) 30n > 1,000
2) n is a multiple of 3.

Can anyone help me in solving this.

According to statement 1. 30n>1000
so 30N can take any values from 1000 to infinity. In such case Hundredth digit always changes.


According to Statement 2 also, N>3, so N take any value.. .in this case also Hundredth digit changes.

So i guess, both statements together are not sufficient to solve
