70 m^3 of air flows in an intake airway towards a working section. Before entering the working section 10 m^3/s is drawn off and passed through a filter leaving with a dust concentration of 120p/ml. 50 m^3 is passed through a bulk air cooler leaving with a dust concentration of 100 p/ml. After the remixing of the air streams and before the air enters the working section,the dust count of the mixture is 130p/ml. Calculate the dust concentration of the original 70 m^3/s.
