Proofread your questions before you post them.

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=22501000
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
