Q: Answer-What is the speed of a boat in still water? Statement I: The boat covers a distance of 120km in...

From I and II Let the speed of the boat be x kmhr Speed of the stream be y kmhr Speed of upstream x y 1205 24i Speed downstream x y 1203 40 .ii From eq. i and ii, we get x 32 kmhr and y 8 kmhr

Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer:

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 II 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 statement II alone are sufficient to answer the question.

D If the data in both statement I and II together are not sufficient to answer the question.

E If the data in both statement I and II together are necessary to answer the question.
