In one alloy there is 15% chromium while in another alloy it is 8%. 15 kg of the first alloy was melted together with 35 kg of the second one to form a third alloy. Find the percentage of chromium in the new alloy.	Choose the correct choice from the following answers
A) 8.8% B) 9% C) 10.1% D) 8.6% E) 8.4%
The amount of chromium in the new 15+35= 
<gadget id="calculator">15+35</gadget>
<output>50</output>
50 kg alloy is  0.15*15+0.08*35= 
<gadget id="calculator"> 0.15*15+0.08*35</gadget>
<output>5.05</output>
5.05 kg, so the percentage is  5.05/50*100= 
<gadget id="calculator"> 5.05/50*100</gadget>
<output>10.1</output>
10.1%.   Answer: 10.1%.
<result>C</result>
