jals11

先感谢楼主提供JJ,

本题如果M,N包含所有>2整数,应该是C吧? 11是>2的整数推出在MUN内,然后11是奇数所以在N内,然后11不是>2的非质数所以不在M内,由此推出11在阴影内,不知对吗?请指教

Tom is going to move, he has three kinds of boxes: large, medium, and small. Now he has already 11 large boxes, each of which is either empty or filled with 6 medium boxes. Medium boxes are filled in the large boxes and each of them is either empty or filled with 6 small boxes. Small boxes are empty and filled in the medium boxes. How many boxes does Tom have?

(1)    he has 56 empty boxes

(2)    he has 42 small boxes

I chose C. large 11

                 medium=empty+ (11-empty)*6
