An alloy contains tin, copper and silver in the ratio 7: 5: 3. If there is 48 mathrm{~g} of copper, how much tin and silver are needed to make the alloy? (4 marks)

Question

Accepted Answer

Step:1 ：Given the ratio of tin, copper, and silver as (7:5:3) and there are (48mathrm{~g}) of copper.Step:2 ：Find the total parts in the alloy: (7+5+3=15).Step:3 ：Find the value of one part: (frac{48}{5}=9.6).Step:4 ：Find the amount of tin needed: (7times9.6=67.2mathrm{~g}).Step:5 ：Find the amount of silver needed: (3times9.6=28.8mathrm{~g}).Step:6 ：(boxed{text{To make the alloy, 67.2g of tin and 28.8g of silver are needed.}})
