Explanation / Answer
1) Every 7 days from 1st day will result in a friday.
3 years and 346 days = 365*3 + 346 = 1441 days
1441 = 205 * 7 + 6
So, Friday + 5 days = wednesday
2) The French monk Marin Mersenne looked at primes of the form 2p 1, with p a prime. They are called Mersenne primes in his honor. Euler also invented formula to generate prime numbers.
