Question

40% of the 7920 visitors to an amusement park were children. 25% of the children and 1/3 of the adults were repeated visitors .how many percent of the visitors were visiting the amusement park for first time ​

Answer 1

Total number of visitors =7920

Children =40% of 7920

Children =0.4×7920=3168

Number of Adults =7920−3168=4752

Number of repeated visitors that are children:=25%×3168

Repeated visitors =0.25×3168=792

Number of children that are visiting for the first time=3168−792=2376

Number of repeated visitors that are adult=

1/3 ×4752=1584

Number of adults that are visiting for the first time=4752−1584=3168

Total number of first time visitors=3168+2376=5544

∴ There are 5544 visitors that are visiting for the first time
