100*50=5000...
property (65*50)+(35*50)=50(65+35).
Distributive property.
I hope it helps

Answer 2

Heya

The number of students in class a are 65

Money contributed by them = 65×50

Number of students in section b = 35

Money contributed by them = 35×50

Total money contributed

= (65×50)+(35×50)

= 50(65+35)

= 50(100)

= Rs. 5000

This was done using distributive property in reverse.

Like, a(b+c) = a×b + a×c

Hope it helps! ^_^
