Physics - Error Question with Solution | TestHub

A physical quantity $Q$ is related to four observables $a,b,c,d$ as follows : $\mathrm{Q}=\frac{\mathrm{ab}{}^4}{\mathrm{cd}}$ where, $\mathrm{a}=(60\pm 3)\mathrm{Pa};\mathrm{b}=(20\pm 0.1)\mathrm{m};\mathrm{c}=(40\pm 0.2){\mathrm{Nsm}}^{-2}$ and $\mathrm{d}=(50\pm 0.1)\mathrm{m}$, then the percentage error in Q is $\frac{x}{1000}$, where $x=$ ________ .
