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 50 kg 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 ?
Answer & explanation
Correct answer: option 3
x = 20 + 45 = 65
y = 40 + 5 = 45
Now , x : y = 65 : 45
13 : 9
