Eight kilograms of oranges contained 98% of water. If the next day the concentration of water decreased by 2%, what was the new weight of the oranges, in kilograms?   (A) 4.9   (B) 4.8   (C) 4.5   (D) 4   (E) 0.2   If D is the answer, then the question means that the concentration of water the newt day became 96%.   Out of 8 kilograms 98%, or 7.84 kilograms was water and 0.16 kilograms was non-water.   The next day, after some water evaporated, oranges became 96% water and 4% of non-water, so the next day 0.16 kilograms of non-water composed 4% of oranges, which means that the new weight of the oranges was x*0.04=0.16 --&gt; x=4 kilograms.   Answer: 4.
