u=me
\n" ); document.write( "m= mother
\n" ); document.write( "n= grandmother
\n" ); document.write( "g= great grandmother
\n" ); document.write( "m=u+21
\n" ); document.write( "n=m+21
\n" ); document.write( "g=n+21
\n" ); document.write( "10y+x=u
\n" ); document.write( "10x+y=g
\n" ); document.write( "We also know that
\n" ); document.write( "y > 0 and y < 10
\n" ); document.write( "x > 0 and x < 10
\n" ); document.write( "g < 100
\n" ); document.write( "There are two possible solutions
\n" ); document.write( "g = 81,n = 60,m = 39,u = 18,x = 8,y = 1
