A physical quantity P is described by the relation
$$P=a^{1 / 2} b^2 c^3 d^{-4}
$$
If the relative errors in the measurement of a, b, c and d respectively, are $\displaystyle 2$%, $\displaystyle 1$%, $\displaystyle 3$% and $\displaystyle 5$%, then the relative error in P will be :
Official answer
(3)
$\displaystyle 32$%
