When processing flower-nectar into honey bees' extract, a considerable amount of water gets reduced. How much flower-nectar must be processed to yield 1kg of honey, if nectar contains 50% water, and the honey obtained from this nectar contains 25% water?	Choose the correct choice.
A) 1.2 kg  B) 1.5 kg  C) 1.7 kg  D) 1.9 kg  E) None of these
Explanation :   Flower-nectar contains 50% of non-water part.   In honey this non-water part constitutes 75% (100-25).   Therefore 0.5 X Amount of flower-nectar = 0.75 X Amount of honey = 0.75 X 1 kg   Therefore amount of flower-nectar needed =   (0.75/0.51)kg=1.5 kgs   Answer : 1.5 kg
