Study the given pie chart and table and answer the question that follows. The 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 table shows the number of boys of class X in six different sections A, B, C, D, E and F.
If the total number of students in section C is 57, then the total number of girls in section C and D together will be: If the total number of students in section C is 57, then the total number of girls in section C and D together will be: |
36 46 48 40 |
46 |
Total number of students in section C = 57 Total number of students in section C = 19% of total number of students ATQ 19% = 57 1% = 3 Now , Number of students in D = 17% = 17 × 3 = 51 Number of girls in C = Total number of students - Total number of Boys = 57 - 34 = 23 Number of girls in D = Total number of students - Total number of Boys = 51 - 28 = 23 Total number of girls in section C & D = 23 + 23 = 46
