Answer 1

Answer:

Let x=Number of Rs 500 prizes given

y=number of Rs 100 prizes given

Since it is given that in that lottery the total of Rs 200 prizes are to be given.

⇒x+y=200 → 1

Since the total prize money 50000

⇒500x+100y=50000 → 2

Solving equation 1 and 2 simultaneously

−4x=−300

x+y=2005x+y=500

x=75

x+y=200

⇒y=125
