Question

an alloy metal consist of 59.5% copper, 29.9% zinc and the remaining lead. find out the weight of alloy, copper and zinc, if weight of lead is 53 kg.​

Answer 1

Answer:

Weight of alloy=500 kg

Weight if copper=297.5 kg

Weight of zinc=149.5 kg

Step-by-step explanation:

Let the weight of alloy be x kg.

Percentage of lead =100-59.5-29.9=10.6%

Then,

$\frac{10.6}{100} \times x = 53$

or

$x = 53 \times \frac{100}{10.6}$

or

$x = 500kg$

Weight of copper=

$\frac{500 \times 59.5}{100} = 59.5 \times 5 = 297.5kg$

Weight of zinc=

$\frac{500 \times 29.9}{100} = 5 \times 29.9 = 149.5kg$
