Question

A gun metal piece consists of 22 parts of copper,2.5 parts of tin and 0.5part of zinc.find the percentage of each metal?

Answer 1

SoluTion :-

No. of parts of Copper = 22

No. of parts of Tin = 2.5

No. of parts of Zinc = 0.5

Total no. of parts = 22 + 2.5 + 0.5 = 25

$\mathrm {Percentage\ of\ Copper =\frac{22}{25} \times 100}\\\\\mathrm {=22 \times 4}\\\\\mathrm {=88 \ \%}$

______

$\mathrm {Percentage\ of\ Tin=\frac{2.5}{25} \times 100}\\\\\mathrm {=2.5 \times 4}\\\\\mathrm {=10 \ \%}$

______

$\mathrm {Percentage \ of \ Zinc = \frac{0.5}{25}\times 100}\\\\\mathrm {=0.5 \times 4}\\\\\mathrm {= 2 \ \%}$

Thus,

Percentage of Copper = 88 %

Percentage of Tin = 10 %

Percentage of Zinc = 2 %

Answer 2

Step-by-step explanation:

Question:-

A gun metal piece consists of 22 parts of copper,2.5 parts of tin and 0.5part of zinc.find the percentage of each metal?

Solution:-

We Have,

$\bf \: parts \: of \: copper \red{= 22 }\\ \\ \bf \: parts \: of \:tin \red{ = 2.5} \\ \\ \bf \: parts \: of \: zinc \red{ =0.5}$

Find It

the percentage of each metal?.

total Parts:-

$\bf \: copper + tin + zinc \\ \\ \bf \red{ putting \: the \: parts }\\ \\ \bf \: 22 + 2.5 + 0.5 = \red{25}$

$\bf \: \frac{100}{25} = 4\% \: each \: parts$

so,

$\bf \: copper \: 22 \times 4 \red{= 88\%} \\ \bf \: tin \: 2.5 \times 4 \red{ = 10\%} \\ \bf zinc \: 0.5 \times 4 \red{ = 2\%}$
