Show answer & explanation
Correct answer: A
Step 1 — Read the relevant rows from the table.
Patients admitted for Viral disease across the four hospitals A, B, C and D are 30, 15, 35 and 10.
Patients admitted for Kidney disease across A, B, C and D are 15, 5, 15 and 5.
Step 2 — Find the total for each disease.
Viral disease total = 30 + 15 + 35 + 10 = 90.
Kidney disease total = 15 + 5 + 15 + 5 = 40.
Step 3 — Form and simplify the ratio.
Required ratio = Viral : Kidney = 90 : 40. Dividing both terms by their HCF, 10, gives 9 : 4.
Therefore, the ratio of patients admitted for Viral disease to Kidney disease is 9 : 4.
