A physical quantity $\displaystyle P$ is related to four observations $\displaystyle a, b, c$ and $\displaystyle d$ as follows: $$P=a^3 b^2 / c \sqrt{d} $$ The percentage errors of measurement in $\displaystyle a, b$, $\displaystyle c$ and $\displaystyle d$ are $\displaystyle 1$%, $\displaystyle 3$%, $\displaystyle 2$%, and $\displaystyle 4$% respectively. The percentage error in the quantity $\displaystyle P$ is
