Answer 2

Answer:

Each student donated 40 rupees on an average.

Step-by-step explanation:

total

=average

let total donated be X

then,

X/40 = 50

(X = 2000 Rupees.)

30 children of class 5 donated 800 Rupees.

Now,

average = \frac{total}{no.}average=

no.

total

Total rupees = 2000+800 = 2800

Total no. of children = 40+30 = 70

Average =>

2800/70

(40) Rupees.

Each student donated 40 rupees on an average.
