asandeep can you explain your logic in chosing D
D is the correct answer.
This is a simple mathematical reasoning question.
the number of reported cases = 100
number of deaths among reported cases = 5
Therefore, % of deaths = 5
the number of reported cases goes down to = 20
number of deaths among reported cases still remains the same = 5
% of deaths = 25
But, since the percentage has increased does that mean the disease is more dangerous ?
Option D says that many cases were not reported, that means that the death percentage was for a lower number of cases.
