Step-by-step explanation:

2) 75-6/100= 74.94%

I think this is correct.. sorry if it's wrong

this is wrong.. ignore it..

Answer 2

$\large \mapsto{ \boxed {\red {\sf{Question : - }}}}$

1)A car showroom sold 100 cars in day , of which 37 were red in colour . what percentage of cars were red in colour?

$\large \mapsto{ \boxed {\green{ \sf{Solution : - }}}}$

$\sf{ \frac{Number \: of \: red \: cars \: sold}{total \: Number \: of \: cars \: sold}} = \frac{37}{100} = 37 \times \frac{1}{100}$

$\frac{1}{100}$can be replaced by the %(percent)symbol.

Hence,the percentage of red cars sold =37%

$\large \mapsto{ \boxed {\red {\sf{Question : - }}}}$

2)In society, 6 out of 75 people are

infected with a common cold . Find the percentage of people infected with the common cold in the society.

$\large \mapsto{ \boxed {\green{ \sf{Solution : - }}}}$

$\sf{ \frac{Number \: of \: people \: infected}{total \: Number \: of \: people}} = \frac{6}{75}$

$= \sf{ \frac{6 \times 100}{7 \times 75}}$

$= \sf{ \frac{6 \times 100}{75} \times \frac{1}{100} }$

$= \sf{8 \times \frac{1}{100} }$

= 89%
