The accuracy in measurement depends on the limit or the resolution of the measuring instrument.A physical quantity `P`is related to four observables `a,b,c` and `d` as `P=(a^3)(b^2)/(cd)^(1/2)`. The percentage errors in measurements of a, b, c and d are `1%`, `3%`, `2%` and `3%` respectively. What is the percetage errors in the measurement of` P`?
