Direction: The following questions are accompanied by three statements A, B and C. You must determine which statement(s) is/are sufficient/necessary to answer the questions and mark your answer accordingly.
In how many hour ‘C’ alone can fill the cistern?
I Ratio of efficiency of A, B and C is 2 : 4 : 5.
II A opened throughout the time, B opened for starting 10 minutes and 'C' opened after 2 minutes of closing of B. A, B and C fill equal amount of water in the cistern.
III If A and B work alternatively, they can fill the tank in 40 minutes.
  • a)
    Any two of them
  • b)
    Either I and II or II and III
  • c)
    I and II together only
  • d)
    Any one of them
  • e)
    Either II or I and III together
Correct answer is option 'A'. Can you explain this answer?

Direction: The following questions are accompanied by three statement...
Statement I makes no meaning alone.
When I and II work alternatively, the individual work can be found and with the statement ‘I’, the time taken for C can be found.
Using II and III the time taken by III can be found.
Using I and III the time taken by III can be found.
Using Any two equations the time taken by III can be found.
Hence, the correct option is (A).

Direction: The following questions are accompanied by three statement...
Understanding the Problem
To determine how many hours 'C' alone can fill the cistern, we need to analyze the provided statements carefully.
Analyzing the Statements
- Statement I: The ratio of efficiency of A, B, and C is 2:4:5.
- This gives us a comparative measure of their efficiencies, which is essential for calculating how much each can contribute to filling the cistern.
- Statement II: A opened throughout the time, B opened for starting 10 minutes, and C opened after 2 minutes of closing B. A, B, and C fill equal amounts of water in the cistern.
- This scenario provides a specific operational sequence and indicates that all three contribute equally to filling the cistern. This information is crucial for understanding the dynamics of their combined efforts.
- Statement III: If A and B work alternatively, they can fill the tank in 40 minutes.
- While this provides a relationship between A and B's combined work, it does not directly inform us about C's efficiency or how long C alone takes to fill the cistern without additional context from the other statements.
Conclusion
To solve the problem of how long 'C' alone can fill the cistern, we need insights from both Statement I and Statement II.
- Statement I establishes the efficiencies of each worker.
- Statement II describes their operational dynamics and the equal contribution to filling the cistern.
Therefore, the correct answer is to choose Any two of them, which means the combination of Statement I and Statement II is sufficient to deduce how long 'C' alone can fill the cistern.
Thus, the answer is option A.
