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.
