A physical quantity $P$ is given as $P=\dfrac{a^2b^3}{c\sqrt d}$. The percentage errors in the measurement of $a$, $b$, $c$ and $d$ are $1\%$, $2\%$, $3\%$ and $4\%$ respectively. The percentage error in the measurement of quantity $P$ will be
Answer: (A) $13\%$
$\dfrac{\Delta P}{P}=2(1)+3(2)+1(3)+\tfrac12(4)=2+6+3+2=13\%$.
