Question 6

Harry, Larry and Parry were each given some marbles on Monday.

On Tuesday, Harry gave Larry and Parry some marbles so that Larry and Parry each ended up with 4 times their original number of marbles.

On Wednesday, Larry gave Harry and Parry some marbles so that Harry and Parry each ended up with 3 times the number of marbles they had on Tuesday.

On Thursday, Parry gave Harry and Larry some marbles so that Harry and Larry each ended up with twice the number of marbles they had on Wednesday.

If Harry, Larry and Parry ended up with 48 marbles each on Thursday, how many marbles did Parry have on Monday?
