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

What is the ratio of the total number of students who scored 140 marks and above to the total no. of students who scored between 60 to 120?

110 : 137

Number of students who scored 140 or more marks = 55 + 40 + 45 = 110

Number of students who scored between 60 and 120 = 32 + 45 + 60 = 137

Ratio = 110  :  137
