Question

The ratio of copper and zinc in an alloy is 9:5. If the weight of copper in an alloy is 48.6 grams, find the weight of zinc in an alloy.

Answer 1

9/5 = 48.6/x
9x = 5 ×48.6
x= 5 × 48.6 /9
x= 5 × 5.4
x = 27
so Weight of Zinc is 27 gm.

Answer 2

Answer:

27 grams.

Step-by-step explanation:

Let the weight of zinc in alloy be x

The ratio of copper and zinc in an alloy is 9:5.

The weight of copper in an alloy is 48.6 grams.

So, A.T.Q

$\frac{9}{5} =\frac{48.6}{x}$

$x =\frac{48.6 \times 5}{9}$

$x =\frac{243}{9}$

$x =27$

Thus the weight of zinc in an alloy is 27 grams.
