Percentages - Quant/Math - CAT 2010
Question 4 the day:
March 17, 2003
The question for the day is from the topic Percentages.
Question:
- When processing flower-nectar into honeybees' 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 15% water?
(1) 1.5 kgs
(2) 1.7 kgs
(3) 3.33 kgs
(4) None of these
Correct Answer - (2)
Solution:
Flower-nectar contains 50% of non-water part.
In honey this non-water part constitutes 85% (100-15).
Therefore 0.5 X Amount of flower-nectar = 0.85 X Amount of honey = 0.85 X 1 kg
Therefore amount of flower-nectar needed = (0.85/0.5) * 1kg = 1.7 kg.
