Hey there! Thanks for the question!

The above $\bold{ Pie \: Chart}$ shows us the presence of various gases in the atmosphere.

From the pie chart, We can draw the following conclusive statements.
1) Nitrogen ( In yellow) occupies the more area in the chart, Hence it is most abundantly available gas.

2) Other gases occupy the least area showing the scarce of their availability

$\bold{ Data \: Interpretation}$ ( Reading the pie chart)

Nitrogen - 78 %
Oxygen - 21 %
Other gases - 1%

Now, Let's answer the following questions based on the above pie chary.

Q. What is percentage of oxygen
$\bold {Answer \colon \: The \: percentage \: of \: oxygen \: is \: 21 \%}$

Q. How much more is Nitrogen than Oxygen
$\bold{Answer \colon \: 57 \% }$

Percentage of oxygen = 21
Percentage of nitrogen = 78
Difference in their percentages = 78 - 21 = 57 .

Q. What is percentage of other gases.
$\bold { Answer \colon \: The \: percentage \: of \: other \: gases \: is \: 1 \% }$
