    i know its not 93 because 10010/93 is not an integer

    when i do 10011/143, its not an integer and neither is 10011/77 so it would be none of these, but that doesnt look like an option

    Ok, here is how you solve: Explicitly write down what number xy0xy is (think positional notation), factorize it and see which factor occurs independently form x and y.
