p and q are both positive integers, are both p & q [#permalink] New post 30 Oct 2007, 23:05
p and q are both positive integers, are both p & q greater than n?

1) p - q > n
2) q > p

Please provide good explanation, thanks

from (i), it may or may not be true.

take p= 9 and q = 1.

9-1= 8 > n

n can be 7!!

so p and q both are not greater in this case.

and possible in case p=10 and q=5 and n =4.

But if you have both (i) and (ii), then p and q are always greater than n. because it will imply that n is a negative number and p and q are given as positive integers. so they will always be greater than n.
