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 40% 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 60% (100-40).   Therefore 0.5 X 1.2 kgmount of flower-nectar = 0.60 X 1.2 kgmount of honey = 0.60 X 1 kg   Therefore amount of flower-nectar needed =   (0.60/0.51)kg=1.2 kgs   1.2 kgnswer : 1.2 kg
