A physical quantity P is related to four observables a, b, c and d as follows $\mathrm{P}=\frac{{\mathrm{a}}^3{\mathrm{b}}^2}{\left(\sqrt{\mathrm{c}}\mathrm{d}\right)}$ The percentage errors of measure-ment in a, b, c and d are 1%, 3%, 4% and 2%, respectively. What is the percentage error in the quantity P? If the value of P calculated using the above relation turns out to be 3.763, to what value should you round off the result
