The following Pie chart represents the percentage-wise distribution of 800 students of class XII in a school in six different sections A,B , C , D , E , and F.
The table given below shows the number of girls in class XII in six different sections A, B, C, D, E and F.
| Section | A | B | C | D | E | F |
| No. of girls | 102 | 80 | 104 | 98 | 0 | 60 |
The total number of girls in sections B, C and D together is what percent more than the total number of boys in sections A, B and D together?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 76.25
The total number of girls in sections B , C, and D = 80 + 104 + 98 = 282.
Number of Boys in section A = 20% of 800 - 102 = 58.
Number of Boys in section B = 18% of 800 - 80 = 144 - 80 = 64
Number of boys in section D = 17% of 800 - 98 = 38.
Number of boys in A, B and D = 58 + 64 + 38 = 160
Rerquired % = (282 - 160)/160 × 100 = 76.25%
