Anne is given the equation $1000 / x = y$
Anne know that $x$ is a positive whole number and $y$ is a $2$-digit positive whole number.
How many combinations of numbers of x and y are possible to solve this equation.
A. 3 B. 4 C. 5 D. 6
Is there a quicker method to working this out other than the way I did (testing likely numbers in the range of x being 11 to 100).
