The total number of students in three classes of a school is 297. The ...
Understanding the Problem:
To solve this problem, we need to find the number of students in each class based on the given ratios. We know the total number of students in the three classes is 297.
Setting up Equations:
Let the number of students in the 6th, 7th, and 8th classes be 5x, 4x, and 3y respectively, where x and y are constants.
According to the given ratios:
5x + 4x + 3y = 297
5x : 4x = 5 : 4
5x : 3y = 2 : 3
Solving the Equations:
From the ratio 5x : 4x = 5 : 4, we get x = 36.
Substitute x = 36 into the first equation:
5(36) + 4(36) + 3y = 297
180 + 144 + 3y = 297
324 + 3y = 297
3y = 297 - 324
3y = -27
y = -9
Therefore, the number of students in the 6th, 7th, and 8th classes are 180, 144, and 108 respectively.
Calculating the Class with the Highest Number of Students:
The class with the highest number of students is the 6th class with 180 students.
Hence, the number of students in the class with the highest number of students is 180, which corresponds to option C) 135.
