In two alloys, copper and tin are related in the ratios of 4:1 and 1:3. 10kg of Ist alloy, 16 kg of 2nd alloy and some pure copper melted together. An alloy obtained in which the ratio of copper and tin was 3:2. Find the weight of the new alloy.
Choose the most appropriate option:
A) 34kg
B) 35kg
C) 36kg
D) 30kg
E) 32kg
suppose x kg of pure copper is melted with 10kg of Ist alloy and 16 kg of 2nd alloy , then   Pure cooper in new alloy = 10*4/5 + 16*1/4 +x = 12+x kg   Pure tin in new alloy = 10*1/5+ 16*3/4=

<output>14</output>
14 kg   As per given condition   (12+x)/14= 3/2   24+2x= 42   x=9 kg   Total weight of new alloy = 10+16+9= 
<gadget id="calculator">10+16+9</gadget>
<output>35</output>
35 kg   ANSWER:35kg
<result>B</result>
