Answer 1

Answer:

Step-by-step explanation:

80kg of alloy of lead and tin contains 40 percent of tin how much tin will be melted to the alloy so that the percentage of tin will be 40 percent of the alloy please in process​

40% of Tin is already there

so nothing to be mixed

Now let say We have to get Lead = 40%

80 kg Alloy has 40% tin

=> Tin = (40/100)*80 = 32 kg

Lead = 80 -32 = 48 kg

Now let say x kg tin is mixed then total Weight =80 + x kg

Lead = 48 kg

% = 40

(48/(80 + x) * 100 = 40

=>480 = 320 + 4x

=> 4x = 160

=> X = 40

40 kg tin to be mixed
