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

If in section E, the ratio of the number of boys to the number of girls is 3 : 4, then the ratio of number of boys in section E to the number of girls in section D is :

18 : 23

Number of Boys in section E =  \(\frac{3}{7}\)×  \(\frac{14}{100}\) ×300

= 18

Number of girls in section D =  \(\frac{17}{100}\) ×300 - 28

= 51 - 28 = 23

Required ratio , 18 : 23
