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)

14.3%

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%
