With the spread of Covid-19 in 2020, it was mandated by Public Health Authorities that each patient admitted in the hospital has to undergo Covid-19 test. In the context of this information, study the table a under and answer the given questions.
Table 1: Number of patients admitted and found COVID-1 9 positive in a district hospital in 2021
If the number of admitted patients increased by 40 percent from March to August 2021 and also, 25 percent of the admitted patients were found Covid-19 positive in August 2021, what was the number of Covid-19 positive patients in August 2021?
The number of admitted patients in March 2021 = 900
By August 2021, the number of admitted patients are increased by 40% from March 2021
= $$(100+40)\%\times\ 900$$
= $$(1.4)\ \times\ 900$$ = $$1260$$
Out of 1260 admitted patients, 25% are covid positive.
Hence the number of covid positive patients are =$$(25)\%\times\ 1260$$
=$$\frac{25}{100}\times\ 1260$$
$$\frac{1}{4}\times\ 1260=315$$ Patients.
