NY primary school organized a 2 day fun fair. admission ticket were sold to each visitor at a cost of \$40
on the first day,120 children visited the funfair more than adult. the number of children on the second day was 25% more than the number of children on the first day. the number of adult on the second day was 5% less than the number of adult on the first day. there was a total of 2570 people at the funfair on the SECOND day
(a)Find the number of adult on the first day.
(b)what was the total sum of money collected at the sale of the admission ticket for both day?

hi,
let's tabulate:
day 1:..........100u..............100u + 120.......200u + 120
day 2:............95u..............125u + 150.......220u + 150

(a) 220u + 150 = 2570
so, 220u = 2420
and, 1u = 11
therefore, no. of adults on first day = 100 x 11 = 1100

(b) total no. of people on both days = 420u + 270 = 4890
so, total collected on both days = 4890 x \$40 = \$195 600

hope this helps.
