It is given that
Amount collected for picnic =Rs2304
We know that
No. of Student + no. of rupees contributed by each student =
2304


Here
It can be written as
=
2×2×2×2×2×2×2×2×3×3


By further calculation
=2×2×2×2×34=48
Therefore, the number of students in class VIII is 4811.

Given : As a part of donation campaign, students of grade VIII collected ₹ 49x² - 84xy + 36y² .

Each student contributed an amount equal to the number of students

To Find : the amount contributed by each student.​

Solution:

49x² - 84xy + 36y² .

= (7x)² - 2(7x)(8x) + (6y)²

a² - 2ab + b² = (a - b)²

= (7x - 8y)²

Each student contributed an amount equal to the number of students

Hence  the amount contributed by each student.​

= | 7x - 8y |
