Correct Answer: 37%
Solution :
From the graph,
⇒ The total number of patients aged less than 45 years = 1 + 4 + 8 = 13
⇒ The total number of patients = 1 + 4 + 8 + 7 + 5 + 4 + 3 + 2 + 1 = 35
$\therefore$ The required percentage
$=\frac{\text{The total number of patients of age less than 45 years}}{\text{The total number of patients}} \times 100=\frac{13}{35}\times 100=37.14\%\approx 37\%$
Hence, the correct answer is 37%.
