Answer:

  • 10, 13, 15.

Step-by-step explanation:

Solve all possible equations:

  • 8 + 10 + 1 + 9 + 2
  • Adding them all up we get:
  • 8 + 10
  • = 18 + 1
  • = 19 + 9
  • = 28 + 2
  • = 30
  • 30 < 40.

10 will be used for the next equation:

2nd equation:

  • 10 + 12 + 1 + 13 + 2
  • Solve:
  • 10 + 12
  • = 22 + 1
  • = 23 + 13
  • = 36 + 2
  • = 38
  • 38 < 40.

13 will be used for the final equation:

Final equation:

  • 10 + 13 + 1 + 15 + 2
  • = 10 + 13
  • = 23 + 1
  • = 24 + 15
  • = 39 + 2
  • = 41.
  • 41 > 40.

The 3 digits are 10, 13, 15.
