Question

An alloy contain 50% copper, 40% zinc and 10% tin. in 2kg of the alloy 500g of more copper was added. find the new percentage of all the metals in the alloy​

Answer 1

Answer:

Step-by-step explanation:

Initial weight of alloy (a) = 2kg =2000g

Weight of copper = 2000*50/100 =1000 g

Zinc = 2000*40/100=800g

Tin = 2000*10/100 = 200g

Final weight = 500+ a = 2500

Copper = 500+1000 = 1500

In% = (1500/2500) 100 = 60%

Zinc= 800 g

In% = (800/2500) 100 = 32%

Tin= 200g

In% = (200/2500) 100 = 8%
