A) \[14\,%\]
B) \[10\,%\]
C) \[7\,%\]
D) \[4\,%\]
Correct Answer: A
Solution :
\[P=\frac{{{a}^{3}}{{b}^{2}}}{cd}\] \[\Rightarrow \,\,\,\frac{\Delta P}{P}\times 100=3\left( \frac{\Delta a}{a}\times 100 \right)+2\left( \frac{\Delta b}{b}\times 100 \right)\] \[\left( \frac{\Delta c}{c}\times 100 \right)+\left( \frac{\Delta d}{d}\times 100 \right)\] \[=3\times 1+2\times 2+3+4\] \[=3+4+3+4=14%\]You need to login to perform this action.
