Direction: In each of the following questions, a question followed by two statements numbered I and II are given. You have to read both the statements and then give the answer
-
What is the speed of the boat in still water ?
I. The boat travels at the speed of 4km/h upstream.
II. The boat travels at the speed of 6km/h downstream.
-
- 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
- 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
- if the data in either Statement I alone or in statement II alone are sufficient to answer the question
- if the data in both the Statement I and II are not sufficient to answer the question
- if the data given in both the Statement I and II are necessary to answer the question
Correct Option: E
We know that,
Speed of boat in still water
= (Speed upstream + Speed downstream)/2
From Statements I and II,
Speed = (6 + 4)/2 = 10/2 = 5 km/h
So, answer can be determined from both statements.
