Answer 1

Answer:

On Average each student of both class will donate Rs. 40.

Step-by-step explanation:

Given:

Number of children in class 6th = 40

On Average Money donated by Each student of class 6th = 50

Number of students in class 5th = 30

Money donated by class 5th = Rs. 800.

To find: Average money that each student donate if both classes taken together

On Average Total money donated by class 6th = 50 × 40 = Rs. 2000

Total money Donated by both class = 2000 + 800 = 2800

Total Number of student in both classes = 40 + 30 = 70

Average = Mean = $\frac{Sum\:of\:observation}{Total\:Numbre\:of\:observation}$

Average = $\frac{2800}{70}=40$

Therefore, On Average each student of both class will donate Rs. 40.
