Class Composition Analysis
The problem states there are 70 students in the class. It also mentions that the number of boys equals the number of girls.
- Total students = 70
- Number of boys = Number of girls
- Therefore, Number of boys = \(\frac{70}{2} = 35\)
- And, Number of girls = \(\frac{70}{2} = 35\)
Suman's Position and Ahead Students
Suman's position is given as 19th from the top. This means there are 18 students ahead of Suman in the class.
The problem also specifies that there are 10 girls ahead of Suman.
- Suman's rank from top = 19
- Students ahead of Suman = Rank - 1 = \(19 - 1 = 18\)
- Number of girls ahead of Suman = 10
We can now determine the number of boys who are ahead of Suman:
- Boys ahead of Suman = Total students ahead - Girls ahead of Suman
- Boys ahead of Suman = \(18 - 10 = 8\)
Calculating Boys Behind Suman
We know the total number of boys in the class and the number of boys ahead of Suman. We can now calculate the number of boys behind Suman.
- Total number of boys = 35
- Number of boys ahead of Suman = 8
- Number of boys behind Suman = Total boys - Boys ahead of Suman
- Number of boys behind Suman = \(35 - 8 = 27\)
So, there are 27 boys behind Suman.
