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 of 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? Correct Answer 76.25

Calculation:

Total number of students = 800

The total number of girls in sections B, C and D together = (80 + 104 + 98) = 282

The total number of students in section A = (800 × 20/100) = 160 

Number of boys in section A = (160 – 102) = 58

The total number of students in section B = (800 × 18/100) = 144

Number of boys in section B = (144 – 80) = 64

The total number of students in section D = (800 × 17/100) = 136

Number of boys in section D = (136 – 98) = 38

The total number of boys in sections A, B and D together = (58 + 64 + 38) = 160

The percentage of the total number of girls in sections B, C and D together to the total number of boys in sections A, B and D together =

⇒ (122/160 × 100)

⇒ (12200/160)

⇒ 76.25%

∴ The required percentage is 76.25
