Find the result of the following expression if, M denotes modulus operation, R denotes round-off, T denotes truncation:

M (373,5) + R (3.4) + T (7.7) + R (5.8)

Explanation

  • M denotes modulus operation, R denotes round-off and T denotes truncation operation.
  • M (373,5): Dividing 373 by 5, remainder will be 3.
  • R (3.4): As 0.4 is less than 0.5, it will be rounded off to 3.
  • T (7.7): Removing fractional part, 7.7 will be truncated to 7.
  • R (5.8): As 0.8 is greater than 0.5, it will be rounded off to 6.
  • Given expression will be reduced to
  • So, value of the given expression will be 19.

Evaluate the expression M (843,11) + R (5.8) + T (7.7) – R (3.4) where M stands for modulo arithmetic, R stands for Round-off operation and T stands for Truncation Operation.

Explanation

  • M denotes modulus operation, R denotes round-off and T denotes truncation operation.
  • M (843,11): Dividing 843 by 11, remainder will be 7.
  • R (5.8): As 0.8 is greater than 0.5, it will be rounded off to 6.
  • T (7.7): Removing fractional part, 7.7 will be truncated to 7.
  • R (3.4): As 0.4 is less than 0.5, it will be rounded off to 3.
  • Given expression will be reduced to
  • So, value of the given expression will be 17.
