1. In a rather wet spring a farmer harvests his barley at 20% water content by weight. He has to dry it partially to deliver to the maltings at 12% water content. How much barley must he harvest to deliver 1 tonne (1000 kg) to the maltings? HOW DO I GET THE CORRECT ANSWER????

so assume the original weight of the barley is 100 which comprises 80 (not water) and W (water) in this case you know that W=20

The equation for the %age of water will be which you know you want to equal 0.12. so just multiply out and solve the equation
