170kg of an alloy A is mixed with 250 kg of alloy B. If alloy A has lead and tin in the ratio 1:3 and alloy B has tin and copper in the ratio 3:5, then the amount of tin in the new alloy is?
Choose the correct answer: A) 210.6kg B) 221.3kg C) 229.5kg D) 110.8kg E) 114kg
Quantity of tin in 170kg of A = 170*3/4= 
<gadget id="calculator">170*3/4</gadget>
<output>255/2 = around 127.5</output>
127.5kg   Quantity of tin in 250kg of 221.3kg= 250*3/8= 
<gadget id="calculator">250*3/8</gadget>
<output>375/4 = around 93.75</output>
93.75kg   Quantity of tin in the new alloy= 127.5+93.75= 
<gadget id="calculator">127.5+93.75</gadget>
<output>221.25</output>
221.25kg   Answer is 221.3kg
<result>B</result>
