The bar chart shows the marks distribution in am English test. What percentage of the students had marks ranging from 35 to 50?

A.

55\(\frac{1}{3}\)%

B.

60%

C.

65%

D.

66\(\frac{2}{3}\)%

Correct answer is D

Percentage of students with marks ranging from 35 to 50 = \(\frac{f_{35} + f{40} + f{50}}{\sum f}\)

= \(\frac{35 + 40 + 45}{20 + 35 + 40 + 45 + 25 + 15}\) x 100%

= \(\frac{120}{180}\) x 100%

= 66\(\frac{2}{3}\)%
