Units & Measurement and Dimensions

A rigid body weighs 25 gram and has a measured volume of $5 \mathrm{~cm}^3$. The possible error in the measurement of mass and volume are 0.01 gram and $0.1 \mathrm{~cm}^3$. The maximum error in the density will be

A physical quantity $\mathrm{P}=\frac{\mathrm{A}^3 \sqrt{\mathrm{~B}}}{\mathrm{C}^{-4} \mathrm{D}^{3 / 2}}$. Out of the quantities $\mathrm{A}, \mathrm{B}, \mathrm{C}$ and D , the quantity which brings maximum percentage error in P is
