\n" ); document.write( "The other tutor tried a solution by trial and error; but an arithmetic error led to an incorrect answer.

\n" ); document.write( "A number y is divided by another number x to get a quotient of a and a remainder of b.

\n" ); document.write( "The same number y is then divided by x/2. There are two possible results:

\n" ); document.write( "(a) the quotient is 2a and the remainder is again b; or
\n" ); document.write( "(b) the quotient is 2a+1 and the remainder is less than b

\n" ); document.write( "In this problem, the remainder when y is divided by x/2 is less than the remainder when it is divided by x. That means we have the second case.

\n" ); document.write( "y divided by x gives remainder 29:
\n" ); document.write( "\"y+=+ax%2B29\" for some integer a

\n" ); document.write( "y divided by x/2 gives remainder 13:
\n" ); document.write( "\"y+=+%282a%2B1%29%28x%2F2%29%2B13\"

\n" ); document.write( "Set the two expressions for y equal to each other and solve the resulting equation:

\n" ); document.write( "\"ax%2B29+=+%282a%2B1%29%28x%2F2%29%2B13\"
\n" ); document.write( "\"ax%2B29+=+ax%2Bx%2F2%2B13\"
\n" ); document.write( "\"29+=+x%2F2%2B13\"
\n" ); document.write( "\"16+=+x%2F2\"
\n" ); document.write( "\"x+=+32\"

\n" ); document.write( "ANSWER: x=32
