Answer/Solution

1900

Steps/Work

Correct Answer: (A)
Determine the range of xy by multiplying the two extremes of each individual range together. The smallest value of xy must be greater than 100 * 20. The largest value must be less than 199 * 100. This means that 2000 < xy < 19,900. (A) is outside of this range, so it is not a possible product of xy.
