People with Type B or O may have a lower risk of severe COVID-19 infection than those with Type A or AB blood.

A research found that COVID-19 patients with Type B or O spent 4.5 fewerdaysintheintensive-care unit (ICU) than those with Type A or AB blood who stayed 13.5 days on average. How long did COVID 19 patients stay in the ICU on average?

1. 7.75 days
2. 9 days
3. 11.25 days

Patients with Type B or O spent 9 days [13.5 – 4.5 = 9] in ICU.

Patients with Type A or AB spent 13.5  days.

The average is 11.25 days [(13.5 + 9)/2 = 11.25].
