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?
Let's think: 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.

A school is planning a community outreach program. Each classroom must raise $200 for this activity. Classroom A has raised $20 from each of two families, $10 from each of eight families, and $5 from each of ten families. How much more money does Classroom A need in order to reach the goal?
Let's think: Classroom A raised 2 x $20 = $40 from two families. They raised 8 x $10 = $80 from eight families. They raised 10 x $5 = $50 from ten families. Altogether, they raised $40 + $80 + $50 = $170. Therefore, they need $200 - $170 = $30 more to reach the goal.. The answer is: 30.

Monica read 16 books last year. This year, she read twice the number of books she read last year. Next year, she wants to read 5 more than twice the number of books she read this year. How many books will Monica read next year?
Let's think: The number of books that Monica read this year is 2 * 16 = 32 books. Twice the number of books that Monica read this year is 2 * 32 = 64 books. The number of books that Monica will read next year is 64 + 5 = 69 books.. The answer is: 69.

Mara has 12 bags with 2 marbles in each bag. Markus has 2 bags with 13 marbles in each bag. How many more marbles does Markus have?
Let's think:
Mara has 2 x 12 = 24 marbles. Markus has 2 x 13 = 26 marbles. Markus has 26 - 24 = 2 more marbles than Mara.. The answer is: 2.
