Hello friend
Total number of prizes are 30
1st prizes are x in number then 2nd prizes will be 30-x in number
__________________________________________________
Total value of prize Money is 52000
We get 52000 but adding the value of 1st prize + value of 2nd prize
Value of 1st prize is 2000x
Value of 2nd prize is 1000(30-x)=30000-1000x
2000x+30000-1000x=52000
1000x+30000=52000
1000x=52000-30000
1000x=22000
x=22
No of first prizes is x=22
No of second prizes is 30-x=30-22=8
Total number of prizes are 30
1st prizes are x in number then 2nd prizes will be 30-x in number

Value of 1st prize is 2000x
Value of 2nd prize is 1000(30-x)=30000-1000x
2000x+30000-1000x=52000
1000x+30000=52000
1000x=52000-30000
1000x=22000
x=22
No of first prizes is x=22
No of second prizes is 30-x=30-22=8
