Question

an alloy contains 4% tin 1% zinc and the remaining copper find the mass in kg of each metal in 5 tonnes of the alloy ​

Answer 1

Answer:

Tin =200 Kg, Zinc =50 Kg and Copper = 4750 Kg.

Step-by-step explanation:

An alloy is made up of Tin, Zinc, and Copper.

We have,  

Tin =4%

Zinc =1% and remaining is Copper

So, Copper = (100-4-1)% = 95%.

Now, we have 5 Tonnes i.e. 5000 Kg of Alloy.

So, in this amount of Alloy, we have Tin= (5000×4/100) Kg =200 Kg of Tin.

And, in this amount of Alloy, we have Zinc= (5000×1/100) Kg = 50 Kg of Zinc.

Similarly, in this amount of Alloy, we have Copper= (5000×95/100) Kg = 4750 Kg of Copper.

Answer 2

Step-by-step explanation:

An alloy contains

Tin = 4%

Zinc = 1%

Copper = (100% - 4% + 1%) = 95%

Now, We have 5 tonnes = 5000 kg of alloy

So,In this amount of Alloy

Tin = 4/100×5000=200kg of Tin

Zinc = 1/100×5000=50kg of Zinc

Copper = 95/100×5000=4750kg of copper
