let childern passs rate is x

then adult pass price will be (x+20)

as adult price is RS. 20 more than the childern pass price

now

200 childern passes are sold

200*x =200x

and 50 adult passes are sold

50*(x+20)

=50x+1000

now total price is 2250

2250=200x+50x+1000

2250=250x+1000

250x=2250-1000

250x=1250

x=1250/250

x=5

now x = childern

so childern pass price is 5

and adult price is 20 more then the childern

so

5+20=25

adult price is 25
