Mixture- Alloy

[Guest]

5 parts of tin and 16 parts of copper are an alloy of bell metal. The weight of a bell is 4200 pounds. Calculate pounds of tin and copper.

Let T = Tin
Let C = Copper

5 T + 16 C = 4200

5 T/5 = 4200/5

T = 840


16C = 4200

16 C/16 = 4200/16

C = 262.5


How do I proceed from here ?

You do not need to proceed from here .... you need to go back to the start ....

5 parts of tin and 16 parts of copper makes 21 parts when added together and that weighs 4200 pounds

So.... 1 part weighs 200 pounds

5 parts weighs 1000 pounds ...this is the tin

16 parts weighs 3200 pounds ...this is the copper

........Simple.........

Thanks for the corrections.

A question:

Would the ratio be 5 : 16 for the tin and copper ?

[Guest]

Would the ratio be 5 : 16 for the tin and copper ?

Yes

[Guest]

Read the ratio ..... 5 : 16 as 5 to 16 .....tin to copper in the alloy

5 parts tin to 16 parts copper

For the batch of 4200 pounds made for the bell that means.....

1000 pounds of tin to 3200 pounds of copper
