That is a multiple choice question, and for that purpose we want quick mental math answers.
\n" ); document.write( "
\n" ); document.write( "\"highlight%28B%29\" is my mental math quick answer.
\n" ); document.write( "Here is how I get to that answer:
\n" ); document.write( "
\n" ); document.write( "C and D make no sense:
\n" ); document.write( "The remainder has to be 23,
\n" ); document.write( "because 37173 = 37150 + 23,
\n" ); document.write( "and 37150, being a multiple of 50, divides evenly by 25.
\n" ); document.write( "
\n" ); document.write( "So, is it A or B?
\n" ); document.write( "Without doing the calculation,
\n" ); document.write( "you know that
\n" ); document.write( "\"37100%2F25=4%2A37100%2F%284%2A25%29=4%2A37100%2F100=4%2A371\" is a number that ends in \"4\".
\n" ); document.write( "So, again without doing the calculation,
\n" ); document.write( "\"37150%2F25=%2837100%2B50%29%2F25=37100%2F25%2B50%2F25=37100%2F25%2B2\" must end in \"4%2B2=6\" .
\n" ); document.write( "
\n" );
