The given 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.
| Section | A | B | C | D | E | F |
| NO. of boys | 36 | 26 | 34 | 28 | -------- | 20 |
If in section E. the ratio of boys and girls is 4 : 3, then the ratio of the number of girls in section B to that of the number of girls in section E is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 14 : 9.
Given that
Ratio of boys and girls in section E = 4 : 3
The number of boys in section B = 26
Now, total number of students in section E = 14% * 300 = 42
The girls in section E = 42 * (3/7) = 18
Total number of students in section B = 18% * 300 = 54
The girls in section B = 54 - 26 = 28
The required ratio = 28/18 = 14/9
Hence, 14 : 9
