ACCA PM Mar/Jun exam on Practice Platform

Hi In the Medical Temp Co question, we are asked to calculated the revised budgeted units for both nurses and doctors. This would be the market share for Medical Temp Co. Market share for nurses is 30% and fo doctors 40% When we calculate18900*30% = 5670 units for nurses it is correct BUT, when we calculate 8200* 40% = 3280 units for doctors, it is incorrect (answer is given at 1640 units). It could be that I am being a serious blonde and overlooking something. Please help. Regards SYS
