By mixing two brands of coffee and selling the mixture at the rate of $177 per kg. a shopkeeper makes a profit of 18%. If to every 2 kg of one brand costing $200 per kg, 3 kg of the other brand is added, then how much per kg does the other brand cost?
Choose the correct answer:
A) $110.66	B) $132.66	C) $116.66	D) $126.66	E) $118.66
C   $116.66   Let the cost of the brand be $X per kg.   C.P. of 5 kg = (2 * 200 + 3 * x) = $(400 + 3x)   S.P of 5 kg = $(5 * 177)= 
<gadget id="calculator">(5 * 177)</gadget>
<output>885</output>
$885   [885 - (400 + 3x)]/(400 + 3x) * 100= 18   24250 - 150x = 3600 + 27x   177x = 20650 =&gt; x = 116 2/3   So, cost of the other brand = $116.66.
