The given pie-chart shows the number of students admitted into various schools, A, B, C, D, E, in a town. The total number of students is 6500. The number of boys in each school is given by the table. Study the pie-chart and the table carefully and answer the question that follows.
Note: For the purpose of calculation, the degree distributions for schools A, B, C, D, and E in the pie chart correspond to total strength proportions that yield total students as follows: A = 1400, B = 1500, C = 1000, D = 1100, E = 1500 (Total = 6500).
Schools A B C D E
Number of boys 800 850 600 700 765
The total number of boys in schools A, C, D is what percentage of the total number of girls in schools B, C, E (rounded to 2 decimal places)?
- A1.2662
- B1.2963
- C1.2863
- D1.2062
Solution & Step-by-step Explanation
Total boys in A, C, D = Boys(A)+Boys(C)+Boys(D)=800+600+700=2100
Total students in B = 1500 → Girls in B = 1500−850=650
Total students in C = 1000 → Girls in C = 1000−600=400
Total students in E = 1500 → Girls in E = 1500−765=735
Total girls in B, C, E = 650+400+735=1785
Required percentage =
1785
