\(\left(\frac{\Delta a+\Delta b}{a-b}\right) \times 100 \%\)
\(\left(\frac{\Delta a}{a}-\frac{\Delta b}{b}\right) \times 100 \%\)
\(\left(\frac{\Delta a}{a-b}+\frac{\Delta b}{a-b}\right) \times 100 \%\)
\(\left(\frac{\Delta \mathrm{a}}{\mathrm{a}-\mathrm{b}}-\frac{\Delta \mathrm{b}}{\mathrm{a}-\mathrm{b}}\right) \times 100 \%\)

Answer

(A) ( a+ b a-b ) 100
