Study the given histogram that shows the height ( in cm) of 100 students in an athletic team and answer the question that follows .
Express the number of students with height less than 170 cm as the percentage ( correct to one decimal place ) of the number of students with height more than 160 cm.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 46.3%
Solution :
number of students with height less than 170 cm = (6 + 12 + 20) = 38
number of students with height more than 160 cm = (20 + 24 + 18 + 16 + 4) = 82
Required percentage = (38/82) × 100 = 46.3 .
Hence the required percentage is 46.3 %.
