• Answer:

  Answer 1 x 9 (number of 1 digit numbers) plus 2 x 89 (number of 2 digit numbers) plus 3(number of 3 digit numbers) x 347 = 1228 The correct answer is 1323. Here is how you do it. 1 digit numbers = 9 2 digit numbers = 90 (99-9) number of 2 digit numbers - number of 1 digit numbers 3 digit numbers = 378 (477-99) number of 3 digit numbers - number of 1 & 2 digit numbers So, the solution is: 1x9 = 9 2x90 = 180 3x378 = 1134 9+180+378 = 1323
