Answer 2

Answer:

I BIT LONG

Step-by-step explanation:

Let x be the numbers of 1st prizes

Hence, 2nd prizes are 30−x in numbers 

ACQ,

2000x+1000(30−x)=52000

⇒2000x+30000−1000x=52000

⇒1000x+30000−52000

⇒1000x=52000−30000

⇒1000x=22000

⇒x=100022000=22

∴30−x=30−22=8

The equation formed is 

2000x+1000(30−x)=52000

⇒2000x+30000−1000x=52000

⇒1000x+30000−52000

⇒1000x=52000−30000

⇒1000x=22000
