total money he got from rides=7200-3000=4200
3 rides-800 students-2400
remaining=4200-2400=1800
only 2rides=1400-800=600
600*2=1200
remaining=1800-1200=600
600 students will go for only single ride=600
students who do not go for any ride=3000-2000=1000

ans-1000.
entry fee of 3000 students=3000
then 800 go for 3 ride=800*3=2400
out of 1400 600 go for exactly two ride=600*2=1200
then 600 go for exactly one ride=600
total no. of student who go to ride=800+600+600=2000
so do not go any ride=3000-2000=1000

total income = Rs.7200-(entry fee rs.3000)= rs.4200 came from rides.
now 1400-800=600 went for only two rides. income from these students is 600*2=rs.1200
income from 800 student = 800*3= rs.2400.
income from only one rides=4200-(2400+1200)=rs.600
therefore 600(student who went only in one ride)+ 1400( who went for atleast 2 rides)= 2000 students...
ans.=1000.

income from entry fee=3000,
800 boys do all 3 rides, so total income from this=800*3=2400,
and 1400 go for atleast 2 rides means 600(=1400-800) do 2 rides. so the income from this=600*2=1200,
now, total income is 7200. from this we can say that 600(=7200-3000-2400-1200)boys do only 1 ride.
so, the no.of boys who do not go for any ride=(3000-800-600-600)=1000 boys
