Maximum absolute error in the sum or difference of two quantities is equal to sum of the absolute error in the individual quantities, i.e.` Z = A + B,` then `± DeltaZ = ± DeltaA ± DeltaB`
Maximum fractional error in a product or division of quantities is equal to the sum of fractional errors in the individual quantities `i.e.' 'AB or A/B,` then `(DeltaZ)/Z=+-(DeltaA)/A+(DeltaB)B`

Options:
(a) `1/40`
(b) `1/50`
(c) `1/100`
(d) `1/200`
