Question : Directions: In each of the following questions, the following histogram shows the relationship between the marks obtained by the students and the number of students in an examination. Study the histogram and answer the questions.
The ratio of the number of students who obtained 60 or more marks to that of students who obtained 60 or fewer marks is:
Option 1: $15:16$
Option 2: $15:19$
Option 3: $14:17$
Option 4: $16:15$
Correct Answer: $16:15$
Solution :
As per the given above histogram, we can see,
Total number of students who obtained 60 or more marks = 19 + 13 = 32
Total number of students who obtained 60 or fewer marks = 5 + 10 + 15 = 30
$\therefore$ Required ratio $=32:30 = 16:15$
Hence, the correct answer is $16:15$.
