You are given an integer N and an integer M. You are supposed to write a method void findBestCoinsThatMinimizeAverage(int N, int M) that prints the best collection of N coins that minimize the average number of minimum coins needed to generate values from 1 to M. So, if M = 100, and N = 4, then if we use the set {1, 5, 10, 25} to generate each value from 1 to 100, so that for each value the number of coins are minimized, i.e. 1 = 1 (1 coin), 2 = 1 + 1 (2 coins),..., 6 = 1 + 5 (2 coins), ..., 24 = 5 + 5 + 5 + 5 + 1 + 1 + 1 + 1 (8 coins), and we take the average of these coins, we would see that the average comes out to ~5.7. But if we instead use {1, 5, 18, 25}, the average would come out to be 3.7. We are to find that set of N coins, and print them, that produce the minimum average.

Basically the interview questions were data structure. The first one was just a simple data structure question, but the second one was mathematical question. I hadn't expected that kind of questions would be asked, so I got really confused. The questions was to prove that Y is a multiple of six, where there are consecutive three numbers X, Y, Z and X and Z are a prime number. I was totally stuck at the point and couldn't make it.
