I feel that I should be able to work out the values for the individual years but I can't work out how to do it and it is driving me slightly mad! A + B + C = 212.91 B + C + D = 277.62 C + D + E = 249.90 There are clearly common terms between pairs of equations but I can only get as far as rearranging the equations so that A=D - 64.71 and B = E + 27.72 (I think!). Is there any way of working out what the actual values for A, B, C, D and E are - being percentages, they are all in the range 0-100. Thanks in anticipation! Rob
