The given histogram represents the marks of students in Science test of class 10th.  The total number of students is 350.

The total no. of students whose marks are less than 80 is what percentage less than the total no. of students whose marks are 120 and above?

67.56%

No. of students who scored less than 80 marks = 32 + 18 + 10 = 60

No. of students who scored 120 or more = 75 + 55 + 40 + 15 = 185

Difference = 185 - 60 = 125

Required percentage → \(\frac{125}{185}\) × 100 = 67.56%
