Question:

If x is the speed of boat in still water, y is the speed of stream, d is the distance and t is the time taken, then

Match List I with List II

List I		List II
A.	Time taken to go upstream	I.	x
B.	Distance travelled downstream in time t	II.	$\frac{2dx}{x^2-y^2}$
C.	Average speed in going d km to and fro	III.	$\frac{d}{x-y}$
D.	Total time taken to go d km downstream and coming back	IV.	$(x+y)t$

Choose the correct answer from the options given below :

Options:

A-IV, B-III, C-II, D-I

A-II, B-IV, C-I, D-III

A-III, B-IV, C-I, D-II

A-I, B-II, C-IV, D-III

Correct Answer:

A-III, B-IV, C-I, D-II

Explanation:

The correct answer is Option (3) → A-III, B-IV, C-I, D-II

List I		List II
A.	Time taken to go upstream	III.	$\frac{d}{x-y}$
B.	Distance travelled downstream in time t	IV.	$(x+y)t$
C.	Average speed in going d km to and fro	I.	$x$
D.	Total time taken to go d km downstream and coming back	II.	$\frac{2dx}{x^2-y^2}$
