A total of rs80000 is to be distributed among 200 persons as prizes.A prize is either RS
500 or RS 100.find the number of each prize​

Answer 1

Answer:

Rs.500/- prize 150 Nos

Rs.100/- Prize   50 Nos

Step-by-step explanation:

Let the number of Rs.500 prize =x

then the number of Rs.100 prize = (200-x)

Now the equation is

500 * x + (200-x) * 100 = 80000

500x+20000-100x = 80000

400x = 80000-20000

x = 60000/400 = 150

Then Rs.500 Prize = 150

         Rs.100 Prize = (200-x) = (200-150) =50

so 500*150 + 100*50 = 75000 + 5000 =80000
