Question

The bar graph shows the marks obtained by some students in ​a math's test. What fraction of students scored less than 70 marks? ​

• A. $\frac{6}{25}$
• B. $\frac{3}{4}$
• C. $\frac{12}{25}$
• D. $\frac{2}{3}$

Answer 1

The correct option is C $\frac{12}{25}$

• Total students that gave the maths test are
  180 + 80 + 120 + 120 = 500.

• And the students who scored less than 70 marks are
  120 + 120 =240.

• Now, the fraction of students that scored less than 70 marks
  =students who scored less than 70 marks / Total Students

• Now, the fraction of students that scored less than 70 marks
  = 240/500

• Now, the fraction of students that scored less than 70 marks
  =12/25.

• So the correct answer is option C.
