　　Explanation

　　The sum of the numbers on all seven cards is1+2+3+4+5+6+7 , or 28. Removing a numbered card reduces the sum of the remaining cards by the number on that card. For example, if the card drawn were numbered 5, then the sum of the remaining cards would be

　　28-5=23, a number whose units digit is 3. Similarly, if the card drawn is numbered 1, then the sum of the numbers on the remaining cards is 27, whose units digit is 7. Therore, the drawn card was numbered 1.
