| Direction: Study the following information carefully and answer the given questions accordingly. Give answer |
| I. After removing 'X' litres of mixture from the jar, 16 litres of water was added to the jar and the ratio of milk to water (m the jar) became 2:1. |
| II. 'X' litres of the mixture constituted 20% of the original quantity of mixture in the jar. |
A) If the-data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to: answer the question.
B) if the data in statement .U alone are sufficient to answer the question while the data in statement I alone are not sufficient to answer the question.
C) if the data either in statement I alone or in statement II alone are sufficient to answer the question.
D) if the data in both the statements I and II together are not sufficient to answer the
E) if the data in both the statements I and II together are necessary to answer the question.
Correct Answer: E
Solution :
Let there be 4y litres of milk and y litres of water in the original mixture, of 5y litres. When x litres mixture is removed, \[\frac{4x}{5}\]litres of milk and \[\frac{x}{5}\] litres of water get removed. From I. \[\frac{4y-\frac{4x}{5}}{y-\frac{x}{5}+16}=\frac{2}{1}\] From II. x = 20% of 5y or x = y Thus, we have two equations and two variables. Hence I and II together are necessary to answer the question.
