Question

-) The ratio of copper and zinc in an alloy is 4:3. Find the weight of each metal in
an alloy whose weight is 413 g.
D​

Answer 1

Answer:

let the common ratio be x

so the copper=4x and

the zinc=3x

total mass of alloy=413g

according to question

4x+3x=413

7x=413

x=413/7

x=59

so the copper = 4×59=236

and the zinc=3×59=177
