Question

The ratio of copper and zinc in an alloy is 4:3 . Find the weight of copper in the alloy whose weight is 413 gm​

Answer 1

Answer:

Given the ratio of copper and zinc in an alloy is 5:3.

Let weight of copper and zinc be 5x and 3x.

Then according to the problem we have,

5x=30.5

or, x=6.1

Then weight of zinc is 3×6.1=18.3 g.

Answer 2

Step-by-step explanation:

The weight of copper and zinc in an alloy :- 413gm

Given ratio of copper and zinc :-4:3

Let the weight of copper :-4x

Let the weight of zinc :-3x

Add the ratio :-7x

Total weight :-413 gms

7x=413

x=413/7

x=59

copper weight =4(x)=4(59)=236gms

zinc weight =3(x)=(59)=177gms

COPPER WEIGHT IS 236 GRAMS..
