Question

Determine the time taken by a pipe R to empty a water

Q: Answer-Determine the time taken by a pipe R to empty a water tank. Statement I: Pipe P and pipe Q can fill...

ATQ, Statement I Let, the total capacity of tank be 120 units. Efficiency of P 1206 20 unitshr Efficiency of Q 1208 15 unitshr Let, the efficiency of R be a unitshr. So, 12023 12020 15 a Or, 12023 12035 a Or, a 12 Time taken by pipe R to empty the water tank 12012 10 hours So, data in statement I alone is sufficient to answer the question. Statement I We cannot determine the relation between pipes P, Q and R. So, data in statement II alone is not sufficient to answer the question.

tank. Statement I: Pipe P and pipe Q can fill a water tank in 6 hours and 8 hours, respectively. If all pipes P, Q, and R are opened together, the time taken by all three pipes to fill the water tank is 120/23 hours. Statement II: Pipe P can fill the water tank in 6 hours, and the ratio of the efficiencies of pipes Q and R is 2:1. The question consists of two statements numbered "l and II" given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.

A The data in both statements I and II together are necessary to answer the question.

B The data given in both statements I and II together are not sufficient to answer the question.

C The data either in statement I alone or in statement II alone are sufficient to answer the question.

D The data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.

E 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.
