Question: Directions: In each of the following questions, a question followed by two statements numbered I and II are given. You are to read both the statements and then give answers.
What is the speed of the boat in still water?
I. The boat travels at the speed of 4 km/h upstream.
II. The boat travels at the speed of 6 km/h downstream.
Options:
A) If the data given in statement I alone are sufficient to answer the question whereas the data given in statement II alone are not sufficient to answer the question
B) If the data given in statement II alone are sufficient to answer the question whereas the data given in statement I alone are not sufficient to answer the question
C) If the data in either statement I alone or in statement II alone are sufficient to answer the questions.
D) If the data in both the statements I and II are not sufficient to answer the question
E) If the data given in both the statement I and II are necessary to answer the question
Show Answer
Answer:
Correct Answer: E
Solution:
- We know that, Speed of boat in still water
$ =\frac{Speedupstream+Speeddownstream}{2} $
From statements I and II, Speed $ =\frac{6+4}{2}=\frac{10}{2} $
= 5 km/h
So, answer can be determined from both statements.
