The following pie chart represents the percentage-wise distribution of 300 students of class X in a school in six different sections A, B, C, D, E and F.

The given table shows the number of boys of class X in six different sections A, B, C, D, E and F.

The total number of boys in sections A, B and D together is what percentage more than the total number of girls in sections A. B and D together?

20%

Number of boys in section A , B & D = 36 + 26 + 28 = 90

Number of girls in A , B & D = Total number of students in A , B & D - Number of boys in section A , B & D 

Total number of students in all sections = 300

Total number of students in A , B & D = \(\frac{20+18+17 }{100}\) ×300

= \(\frac{ 55 }{100}\) ×300

= 165

Total number of girls = 165 -  90 = 75

Percentage of more boys in A , B & D than girls in A, B & D

= \(\frac{ 90-75 }{75}\) × 100

= \(\frac{ 15 }{75}\) × 100

= 20%
