Question : The given histogram shows the height of the students.
What is the percentage of students whose height is in the class interval 160 -170?
(correct to the nearest integer)
Option 1: 51
Option 2: 34
Option 3: 25
Option 4: 39
Correct Answer: 34
Solution :
According to the question
Total Students = 15 + 13 + 10 + 14 + 12 + 6 = 70
Students in class interval 160 - 170 = 10 + 14 = 24
⇒ Required percentage = $\frac{\text{Student in class interval 160- 170}}{\text{Total Students}}$ = $\frac{24}{70}$ × 100 = 34.2
Hence, the correct answer is 34%.
