Statement I: For positive integer $n < 20, n! (20 - n)!$ is least at $n = 10$ . Statement II: $(r 2 m)$ is largest at $r = m$ .

Options:

Answer:

Solution:

$n! (20 - n)! = 20! / (n 20)$ . The denominator is largest at $n = 10$ by II, so both statements are true and II explains I. Printed answer D is wrong.
