Let X= No.of Families donating Rs.50
Let Y= No.of Families donating Rs.100
The equation is  
50x+100y=44450
if x=111
So no.of people donate Rs.100=
50(111)+100y=44450
5550+100y=44450
100y=44450-5550
y=38900/100
then y = 389

As y= No.of Families donating Rs.100

Let The No.Of Family Donated rs 100 = x
According To given statement
100x + 50 * 111 = 44450
100x = 44450 - 5550
100x = 38900
x = 389

389 families Donated Rs 100
