30g of soil are dispersed in 1000 ml of solution. A 10 ml pipet is used to collect the fraction smaller than 0.002mm which is then transferred to a beaker dried, and weighed.  The pipetted fraction is found to weigh 0.07 g.  The material greater than 0.05 mm is collected on a sieve, dried and found to weigh 10g.  What are the percentages of sand, silt, and clay?
