a total of 30 prizes are to be given A price is either 500 100. Find the number preach type of the total prize money 50000​

Answer 1

Answer:

Step-by-step explanation:

Total prize money =

50000

Let the number of 500 rs prize be x

Hence the number of 100 rs prize = 200 - x

Total amount for 500 rs prizes = 500 × x = 500 x

Total amount for 100 rs prizes = (100 x (200 -x) = 20000 -100x

=> 500x + 20000 - 100x = 50000

=>400x = 50000-20000

x = 30000/400

x = 75

No of 500 rs prize,= 75

No of 100 rs prize = 200- 75 =125

Answer 2

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=−300x+y=2005x+y=500

x=75

x+y=200⇒y=125
