Question

In a survey it was found that 13 students like table tennis, 15 students like basketball, 17 students like cricket and 11 students like badminton. Estimate the total number of students surveyed?

Answer 1

Number of students who like table tennis = 13
Estimate 13 as 10.
Number of students who like basketball = 15
Estimate 15 as 20.
Number of students who like cricket = 17
Estimate 17 as 20.
Number of students who like badminton = 11
Estimate 11 as 10.
Total number of students = 10 + 20 + 20 + 10 = 60
So, approximately 60 students were surveyed.
