conversations.value: Break down this math problem: The total number of years in a century is the same as the number of marbles Gideon has. If he gives 3/4 of the marbles to his sister and multiples the number of remaining marbles by 2, he gets his age five years from now. How old is Gideon now?

conversations.value: A century has 100 years, and if Gideon has as many marbles as the number of years in a century, he has 100 marbles.
  If he gives 3/4 of the marbles to his sister, he gives out 3/4*100 = 75 marbles.
  Gideon's total number of marbles remaining after giving 3/4 of the marbles to his sister is 100-75=25.
  When he multiplies the number of remaining marbles by 2, he gets his age five years from now, meaning he will be 25*2=50 years old five years from now.
  Currently, Gideon is 50-5 = 45 years old.
