0 Guest Posted April 16, 2010 Report Share Posted April 16, 2010 When you need abc to represent a 3 digit number you write them in capitals like this: ABC ABC ABC + ___ BBB So 3*ABC=BBB right? So A can't be 0 (unless all of them are zeros then 000+000+000=000 which could be an answer) So A can be either 1, 2 or 3. 300A + 30B + 3C = 100B +10B + B 300A + 3C = 81B 100A + C = 27B 100A + C = A0C A0C has to be divisible by 9, so according to the laws of 9 divisibility A+C can be divided by 9, A as we said before can only be 1, 2 or 3 (otherwise the sum would be larger than 1000) So C can be 8, 7 or 6. So here are the possibilities: (A,B,C) (1,B,8) (2,B,7) (3,B,6) The only pair that have an integer result for B in 100A + C = 27B is 1 and 8 so A=1 B=4 C=8 148*3=444 Quote Link to comment Share on other sites More sharing options...

0 Guest Posted April 23, 2010 Report Share Posted April 23, 2010 B=1, 111/3=037 X B=2, 222/3=074 X B=3, 333/3=111 X B=4, 444/3=148 O B=5, 555/3=185 X B=6, 666/3=222 X B=7, 777/3=259 X B=8, 888/3=296 X B=9, 999/3=333 X So this ensures that it's 148+148+148=444 Quote Link to comment Share on other sites More sharing options...
