STEP-BY-STEP-EXPLANATION
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 × (200 - x) = 20000 -1 00x
=> 500x + 20000 - 100x = 50000
=>400x = 50000-20000
400x = 30000
x = 30000/400
x = 75
No of 500 rs prize ,= 75
No of 100 rs prize = 200 - 75 =125
