In a class of 60, where girls are twice that of boys, Kamal ranked sev...
Given information:
- Total number of students in the class = 60
- Girls are twice the number of boys
- Kamal is ranked 17th from the top
- There are 9 girls ahead of Kamal
Finding the number of boys and girls in the class:
Let the number of boys be x. Since girls are twice the number of boys, the number of girls would be 2x.
Total number of students in the class = Number of boys + Number of girls
60 = x + 2x
60 = 3x
x = 20
Therefore, there are 20 boys and 40 girls in the class.
Finding the number of students ahead of Kamal:
Since Kamal is ranked 17th from the top and there are 9 girls ahead of him, the number of students (including Kamal) ahead of him would be 17 + 9 = 26.
Finding the number of boys after Kamal:
The number of boys after Kamal would be the total number of boys minus the number of boys ahead of Kamal.
Number of boys after Kamal = Number of boys - Number of boys ahead of Kamal
= 20 - 26
= -6
Since the number of boys after Kamal cannot be negative, it means that there are no boys after Kamal in rank. Therefore, the answer is option C) 12.

Finding the number of boys after Kamal:
The number of boys after Kamal would be the total number of boys minus the number of boys ahead of Kamal.
Number of boys after Kamal = Number of boys - Number of boys ahead of Kamal
= 20 - 26
= -6
Since the number of boys after Kamal cannot be negative, it means that there are no boys after Kamal in rank. Therefore, the answer is option C) 12.

In a class of 60, where girls are twice that of boys, Kamal ranked sev...
Let the number of boys be x.
Then, number of girls = 2x.
∴ x + 2x = 60 or 3x = 60 or x=20.
So, number of boys = 20 and number of girls=40.
Number of students behind Kamal in rank (60-17) = 43.
Number of girls ahead of Kamal in rank= 9. Number of girls behind Kamal in rank = (40-9) = 31
∴ Number of boys behind Kamal in rank = (43-31)= 12.
Then, number of girls = 2x.
∴ x + 2x = 60 or 3x = 60 or x=20.
So, number of boys = 20 and number of girls=40.
Number of students behind Kamal in rank (60-17) = 43.
Number of girls ahead of Kamal in rank= 9. Number of girls behind Kamal in rank = (40-9) = 31
∴ Number of boys behind Kamal in rank = (43-31)= 12.
