Question: At the duck park, there are 25 mallard ducks and ten less than twice as many geese as ducks. Then, a small flock of 4 ducks arrived at the park and joined the birds already there. If five less than 15 geese leave the park, how many more geese than ducks remain at the park?
Answer: Initially, twice as many geese as ducks is 25 * 2 = 50 geese. Therefore, ten less than twice as many geese as ducks is 50 - 10 = 40 geese. Then, 4 ducks arrived at the park, resulting in 25 + 4 = 29 ducks. Five less than 15 geese is 15 - 5 = 10 geese. Thus, if 5 less than 15 geese leave, then 40 - 10 = 30 geese remain. Thus, there are 30 - 29 = 1 more geese than ducks remaining at the park. The answer is 1.

Q: Exactly two-fifths of NBA players who signed up for a test are aged between 25 and 35 years. If three-eighths of them are older than 35, and a total of 1000 players signed up, how many players are younger than 25 years?
A: Two - fifths of 1000 players is (2 / 5) * 1000 = 400 players. Three eights of 1000 players is (3 / 8) * 1000 = 375 players. The total number of players 25 or older is 400 + 375 = 775. The number of players younger than 25 years is 1000 - 775 = 225 players. The answer is 225.
