635 kg of fine aggregate and 910 kg of coarse aggregate are needed to be mixed for producing 1m3 of concrete. Fine aggregate had the moisture content of 2.5% and absorption of 3.2%, whereas the coarse aggregate had the moisture content of 1.35% and absorption of 2.41%. Find the amount of water required to increase the moisture contents of both fine and coarse aggregate to reach absorption?
