Numbers that are divisible by 2 are even numbers. Since any number that ends in 5 is not an even number, the number we are looking for must end in 0. Numbers that are divisible by 3 have a sum of digits that is divisible by 3. Since 7 is not divisible by 3, any number that qualifies by the fact that the sum of the digits is 7 also qualifies on non-divisibility by 3. Since this is a 3-digit number less than 300, the hundreds digit must be either 1 or 2. 7 minus 1 is 6, so one possibility is 160. 7 minus 2 is 5 so the other possibility is 250.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "John \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
