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.
| Section | A | B | C | D | E | F |
| No. of boys | 36 | 26 | 34 | 28 | --- | 20 |
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?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 20%
Explanation:
According to the given data,
The total number of boys in sections A, B and D together = (36 + 26 + 28) = 90
Total number of students in class A = 20% of 300 = 60
Number of girls in class A = 60 - 36 = 24
Total number of students in class B = 18% of 300 = 54
Number of girls in class B = 54 - 26 = 28
Total number of students in class D = 17% of 300 = 51
Number of girls in class D = 51 - 28 = 23
Total number of girls in classes A, B and D = 24 + 28 + 23 = 75
Required difference = 90 - 75 = 15
Now, percentage difference = = 20%
Hence the required answer is 20%.
