In April 2021, if the respective ratio of the number of admitted patients to the number of patients found Covid-19 positive was 5:4: then the number of female Covid-19 positive patients constitute what percent of the number of admitted patients in April 2021?

Let the number of admitted patients in April 2021 be $$5x$$

and  the number of patients found Covid-19 positive was be $$4x$$.

From the table, in April 2021 the ratio of the number of covid positive male patients to covid positive female patients is 

given as 5:3.

The number of covid positive female patients in April 2021 = $$\frac{3}{3+5}\times\ $$ total covid positive patients

= $$\frac{3}{3+5}\times\ 4x$$ = $$\frac{3}{8}\times\ 4x\ =\ \frac{3x}{2}$$.

Hence, the percentage of the number of covid positive female patients in the number of admitted patients =

= $$\ \frac{3x}{2\ \times\ 5x}\times\ 100$$ = $$\ 30$$

Option (A) is correct.
