Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and knowledge of Mathematics to choose between the possible answers. There are two jars which contain different liquids in different quantities Quantity I∶ Quantity of water in Jar 1, if Jar 1 contains mixture of 230 litres which contain juice, water, coke and pepsi. Ratio of quantity of water to juice is 2 : 1 and juice to coke is also 2 ∶ 1 while the ratio of quantity of coke to pepsi is 3 ∶ 2 Quantity II∶ Quantity of water in Jar 2, if Jar 2 contains 10 litres of mixture more than jar 1 and contains juice, coke and water. Water, juice and coke is poured into the jar 8 times in the ratio 3 ∶ 2 ∶ 1. Every time the quantity of a liquid is same.
Bottled water is drinking water (e.g., well water, distilled water, mineral water, or spring water) packaged in PET Bottle or Glass Water Bottles. Bottled water is comprehensively regulated by the U.S. Food and Drug Administration (FDA) as a packaged food product. By law, the FDA regulations for bottled water must be at least as stringent as the Environmental Protection Agency standards for tap water. What inference can be drawn from the above passage?
A three-star medicine is prepared by mixing two type of fluids (A & B) in ratio of 1 : 4. Fluid A is prepared by mixing two type of water, water M and water N in ratio of 4 : 5. Fluid B is prepared by mixing two type of water, water X and water N in ratio of 3 : 7. The final mixture is prepared by 675 units of three-star medicine with water Y. If the concentration of the water N in the final mixture is 60%, then how much water Y had been added to three-star medicine?

About 40 million people (over 75% are children) are affected by water borne diseases every year. Nearly six million children below 14 years of age suffer from fluorosis due to fluoride contamination in water. Arsenic is another dangerous contaminant in ground water, putting at risk more than 10 million people in the country. Bacteriological contamination, which leads to diarrhea, cholera, hepatitis etc., is at alert level in India. Contamination due to Iron, hardness and salinity in water are other major concern. Medical expenditure on water borne diseases is estimated to be Rs. 2400 crores annually in the country. The need for desalination and water purification is destined to grow in the coming years as the requirement for water increases. Bhabha Atomic Research Centre (BARC) has been engaged in R&D on desalination and water purification technologies for several years and has developed indigenous technologies which are available for know-how transfer to interested parties The given information, if accurate, most accurately supports which statement?
