Table 1: Number of patients admitted and found COVID-19 positive in a district hospital in 2021

Question 88

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?

Solution

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.

Option (D) is correct.
