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.
| Section | A | B | C | D | E | F |
| No. of boys | 36 | 26 | 34 | 28 | x | 20 |
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 :
Answer & explanation
Correct answer: option 4
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
