Answer 1

Step-by-step explanation:

let the number of ₹100 prize be x and ₹500 prize be y.

total prize to be distributed= 100

x + y = 100

x = 100 - y -----(1)

total money = ₹20000

100x + 500y = 20000

100 ( 100 - y) + 500y = 20000

400y = 10000 => y = 25

from (1)

x = 100 - y = 100 - 25 = 75

x = 75

Answer:

--------------

₹100 prize = 75 , ₹500 prize = 25
