Question

Accounts population increased by 1200 people and this then new population decrease 11%

Answer 1

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
