A man can row downstream at 20 kmph and upstream at 12 kmph. Find the speed of the man in still water and the speed of stream respectively?
Pick.
A) 13, 3	B) 12, 6	C) 16, 4	D) 14, 4	E) None of these
Explanation:   Let the speed of the man in still water and speed of stream be x kmph and y kmph respectively.   Given x + y = 20--- (1)   and x - y = 12 --- (2)   From (1) &amp; (2) 2x = 32 =&gt; x = 16, y = 4.   Answer: Option 16, 4
