Question

The ratio of copper & zinc in a alloy is $9:5$. If the weight of copper in the alloy is $48$, gram, find the weight of zinc in the alloy.

Answer 1

Ratio of copper and zinc in alloy$=9:5$

Weight of copper$=48ℊ$

Let weight of zinc$=x$

$\frac{9}{5}=\frac{48}{x}$

$9x=5\times 48$

$x=\frac{240}{9}$

$x=25.5ℊ$

$\therefore$Weight of zincin the alloy is $25.5ℊ$
