A man purchases 2 watches for $ 560. He sells one at 15% profit and the other at a loss of 10%. He neither gains nor loses on the whole. Thus, the cost price of two watches are : Select
A) $ 260 and $ 300	B) $210 and $ 350	C) $224 and $336	D) $560 and $560	E) $224 and $ 350
x + y = 560 --- (1)   1.15x + 0.9y = 560 --- (2)   (2) - (1) --&gt; 0.15x - 0.1y = 0   15x = 10y   x/y = 2/3 = (2*112)/(3*112) = 224/336   Answer: $224 and $336
