1 The number of upper and lower cups remains unchanged.

There are two cups missing from the top, two cups missing from the bottom or two cups missing from the top and two cups missing from the bottom.

It turns out that the number of cups up is odd, so the answer can't be completely turned over.

7*2* 1.33*23+4.74*4*39+4.74*2*76=7* 1.33*23*2+4.74*7*2*22= 14*( 1.33*23+4.74*22)
