If `X= A xx B and Delta X Delta A and Delta B` are maximum absolute error in X ,A and B respectively , then the maximum relative in X is given byA. `Delta X = Delta A + Delta B`B. `Delta X = Delta A - Delta B`C. `(Delta X)/(X) = (Delta A)/(A) - (Delta B)/(B)`D. `(Delta X)/(X) = (Delta A)/(A) + (Delta B)/(B)`

Answer» Correct Answer - d
When two quantities are multiplied, their maximum relative errors areadded up
Hence `(Delta X)/(X)= (Delta A)/(A)+ (Delta B)/(B)`
