Psychrometry and Grain Drying

A batch of $1000\text{ kg}$ of grain is dried from initial moisture $M_{1} = 25\%$ (wet basis) to final moisture $M_{2} = 15\%$ (wet basis). Using the dry matter balance $W_{dry} = 1000 \times (1 - 0.25) = 750\text{ kg}$, the final weight of dried grain $W_2 = \frac{750}{1 - 0.15} = \frac{750}{0.85}$ in kg is (rounded off to one decimal place):
