A factory makes chocolate bars. Five boxes, labelled V,W,X,Y,ZV, W, X, Y, Z, are each packed with 20 bars. Each of the bars in three of the boxes has a mass of 100 g. Each of the bars in the other two boxes has a mass of 90 g. One bar is taken from box VV, two bars are taken from box WW, four bars are taken from box XX, eight bars are taken from box YY, and sixteen bars are taken from box ZZ. The total mass of these bars taken from the boxes is 2920 g. Which boxes contain the 90 g bars?
