If $a, b, c$ are the percentage errors in the measurement of $A, B$ and $C$, then the percentage error in $ABC$ would be approximately

A

$abc$

B

$a + b + c$

C

$ab + bc + ac$

D

$\frac{a}{b}\,\, + \;\,\frac{b}{c}\,\, + \;\,\frac{c}{a}$

Solution

$\frac{\Delta ABC }{ ABC }=\frac{\Delta A }{ A }+\frac{\Delta B }{ B }+\frac{\Delta C }{ C }$

$= a + b + c$
