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)
A20
B29
C19
D39
Answer: Option C
Explanation:Modulus gives a remainder: M(373,5) = 3, since 5*74 = 370 Rounding rounds to the nearest integer: so R(3.4) = 3, and R(5.8) = 6 and Truncation 'rounds' to an integer by removing any decimal fractions, so T(7.7) = 7 adding the answers above gives 3+3+6+7 = 19
