A metal is made by adding copper and zinc in the ratio of 3:11.
This new metal is then taken and mixed with more zinc in the ratio 2:3.
how much copper would be there in 4200kg of the final metal?
:
Find what fraction is zinc in the first metal:
=
:
Mixed with more zinc 2:3 = is zinc
then
* = is now zinc
then
- = is now copper
:
*4200 = 2220 kg is copper
