David, Ethan and Tim have some marbles. The ratios of their marbles are as follows: David : (David + Ethan + Tim) = 1 : 5 Ethan : (David + Tim) = 1 : 3 Tim has 42 marbles more than Ethan. In the end, Tim gives away all he has to Ethan and David so that both Ethan and David end up with the same number of marbles, how many marbles has Ethan received from Tim?
