B) \[5%\]
C) \[9%\]
D) \[8\,%\]
Correct Answer: A
Solution :
\[\frac{\Delta x}{x}\,\,\times \,100=\frac{3\Delta a}{a}\,\times 100+\frac{3\Delta b}{b}\,\times 100\] \[+\frac{3\Delta c}{c}\times 100\,\,+\,\,\frac{1}{2}\,\frac{3\Delta d}{d}\,\times 100\] \[%\,error\text{ }in\text{ }x=3\times 2+3\times 1+2\times 1+4\times \frac{1}{2}\] \[=\text{ }13\,%\]You need to login to perform this action.
