A man can row downstream at 26 kmph and upstream at 10 kmph. Find the speed of the man in still water and the speed of stream respectively? Choose the correct choice.
A) 2, 9	B) 4, 9	C) 8, 9	D) 18, 8	E) 7, 9
Let the speed of the man in still water and speed of stream be x kmph and y kmph respectively.   Given x + y = 26 --- (1)   and x - y = 10 --- (2)   From (1) &amp; (2) 2x = 36 =&gt; x = 18, y = 8.   Answer:18, 8
