Cate bomboane a impartit irina, in totoal daca i-a dat fiecareia dintre cele 4 prietene cate 3 bomboane cu lapte si cate 5 bomboate cu ciocolata?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
