If 0 < r < 1 < s < 2, which of the following must be less than 1?
I) r/s
II) rs
III) s - r
A - I only
B - II only
C - III only
D - I and II
E - I and III
The answer, which is A (highlight to see the answer), doesn't convince me.
I am having a difficulty understanding why rs will not necessarily be less than 1. Having picked numbers from many examples for r and s, my calculations show that rs will always be less than 1. Have I not come up with a good guess?
