Answer:

Correct Answer: B

Solution:

  • Given, $ 12\frac{1}{12}+12\frac{1}{12}\div 12\frac{1}{12}-12\frac{1}{12} $

$ \Rightarrow $ $ \frac{12\times 12+1}{12}+\frac{12\times 12+1}{12}\times \frac{12}{12\times 12+1} $ $ -\frac{12\times 12+1}{12} $

$ \Rightarrow $ $ \frac{145}{12}+\frac{145}{12}\times \frac{12}{145}-\frac{145}{12} $
$ \Rightarrow $ $ \frac{145}{12}+1-\frac{145}{12}=1 $
