Given that 100<x<199 and 10<y<100, we will have 1,000 < xy < 19,900. The maximum value of xy would be less than 19,900; thus, option E is incorrect.

Correct answer: E

Hope this helps!

\(100 < x < 199\) and \(10 < y < 100\)

Since ALL \(+\)ve & same sign , directly multiply,

\(1000 < xy < 19900\)

The only product which does NOT lie between \(1000\) and \(19900\) is E (\(19,909\))
