Answer

For political party A Number of seats won in $2004 = 206$
Number of seats won in $2009 = 145$
Decrement in the number of seats won by party $A = 206-145=61$
$\text{Decrease}\%=\frac{61}{206}\times100=29.61\%$
For political party $B$, Number of seats won in $2004= 116$
Number of seats won in $2009 = 138$
Increment in the number of seats won by party $B = 138 - 116 = 22$
$\text{Increase}\%=\frac{22}{116}\times100=18.96\%$
For political party $C$, Number of seats won in $2004 = 4$
Number of seats won in $2009 = 24$
Increment in the number of seats won by party $C = 24 - 4 = 20$
$\text{Increase}\%=\frac{20}{4}\times100=500\%$
For political party $D$,
 Number of seats won in $2004 = 11$
Number of seats won in $2009 = 12$
Increment in the number of seats won by party $D = 12 - 11 = 1$
$\text{Increase}\%=\frac{1}{11}\times100=9.09\%$
