Let's assume total population= p
So increased population= p+1200
Now after 11% decrease population= p-32
So total decreased population= 1200+32= 1232
11% of 1200 = 1200×11/100 =132
So 11% of p = 1232-132 = 1100
If 11% of p = 1100
Then 1% of p = 1100/11
and 100% of p = 1100/11×100 =10000
So original population was= 10000
So increased population= p+1200
Now after 11% decrease population= p-32
So total decreased population= 1200+32= 1232
11% of 1200 = 1200×11/100 =132
So 11% of p = 1232-132 = 1100
If 11% of p = 1100
Then 1% of p = 1100/11
and 100% of p = 1100/11×100 =10000
So original population was= 10000
