The histogram shows the weights of students of class X in a school.

Let x be the number of students whose weight is less than 50kg and y be the number of the students whose weight is greater than or equal to 60 kg. What is the value of x : y?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 13 : 9
Let x be the number of students whose weight is less than 50 kg = 20 + 45 = 65
Let y be the number of students whose weight is greater than or equal to 60 kg = 40 + 5 = 45
Required ratio of x and y = 65 : 45
⇒ 13 : 9
