The given histogram shows the height of the students.
The number of students whose height is in the class interval 170-175 is what per cent less than the number of students whose height is in the interval 165-170? (correct to one decimal place)
Answer & explanation
Correct answer: option 1
Students with height in b/w 170-175 = 12
Students with height in b/w 165 - 170 = 14
Required percentage = \(\frac{14 - 12}{14}\) × 100
= \(\frac{2}{14}\) × 100
= 14.3%
