I have been asked this question in an international level competition.

My doubt stems from Data Handling topic in division Data Handling of Mathematics – Class 8

Answer 1

Correct option is (b) 0-10 and 30-40

For explanation I would say: Frequency gives the number of times that an entry occurs. The frequency of 0-10 and 30-40 is same and equal to 4.
