Marginal and absorption costing again

Please can someone help me with this question it is on the practice ecr paper. I have been staring at it all day and have given up.
Direct Materials............£19600
Direct Labour..........£21280
Variable Pro O/H.......£17920
Fixed Pro O/H...........£29120
Admin etc.........£33600
Total costs..........£121520
O/H absorption rate is £5.20
Opening stock 5000 units
Closing stock 4200 Units
I need to work out the marginal cost profit and the absorption cost profit. I have worked out the marginal cost per unit, the absorption cost per unit and cost of sales for both. But how do I work out the profit without the sales figures?
