You have the nine distinct digits 1,2,3,4,5,6,7,8 and 9.You are allowed to form 3 numbers each of 3 digits from these,without using any digit more than once..The requirement is that the total of these 3 numbers should be 900.Try forming the numbers.
A few possibilities I found: (189, 276, 435), (289, 175, 436), (176, 235, 489) etc. The logic I used was the first digit of all 3 numbers should be 1 or 2 or 4, the second digit should be 3 or 7 or 8, and the last digit should be 5 or 6 or 9. Using this you can get several groups of 3 numbers that total to 900.
