Step-by-step explanation:

Given If 29-1=30. 9-1=10. 14-1 =15. Based on the above logic can you prove 11-1=10

I think it is a puzzle which can be solved using Roman numerals as follows

   29 - 1 = 30

  X X 1 X - 1 = XXX = 30

   9 - 1 =  10

 1 X - 1 = X = 10

  14 - 1 = 15

 X 1 V - 1 = X V = 15

 11 - 1 = 10

X 1 = 1 = X = 10

Thus the puzzle can be solved in the above manner.
