35+15+10+12=72 divide 4=18*5=90
\n" ); document.write( "I guessed and checked by dividing 95 by 5 and getting 19, so i guessed and checked for 100 and got 20.
\n" ); document.write( "100 divide 5=20
\n" ); document.write( "100-72=28
\n" ); document.write( "28+35+15+10+12=100 divide 5=20
\n" ); document.write( "So the answer is 28.
