Let X is the initial population of Male and Y be the initial population of Female

X + Y = 5500 .........(1)

If the number of males increases by 11 % and the number of females increases by 20 %, then

1.11 X + 1.2 Y = 6330 , On putting the value of X from equeation (1)

1.11 ( 5500 - Y ) + 1.2 Y = 6330

Y = 2500,
But after increasing the 20% population of females
y=1.2*2500
=>y=3000
so correct option is b)3000
