    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
