A certain number of two digits is 7 times the sum of its digits and increases by 27 when it is reversed.What is the number? \n" ); document.write( "-------- \n" ); document.write( "increases by 27 when it is reversed --> the digits differ by 3 \n" ); document.write( "---- \n" ); document.write( "--> find a multiple of 7 whose digits differ by 3 \n" ); document.write( "03 NG \n" ); document.write( "14 NG \n" ); document.write( "25 NG \n" ); document.write( "36 NG \n" ); document.write( "47 NG \n" ); document.write( "58 NG \n" ); document.write( "69 NG \n" ); document.write( "=========== \n" ); document.write( "No solution. \n" ); document.write( "--------- \n" ); document.write( "If it decreases by 27, then 63 works. \n" ); document.write( "============ \n" ); document.write( "The other tutor says 36, but 36 is not 7*(3+6) \n" ); document.write( " |
