Let the tot. population a year ago = x
10/100x + x = 22000
10x + 100x = 2200000
110x = 2200000
x = 20000...................ANS

HELLO FRIEND HERE IS YOUR ANSWER,,,,,,,,,
By applying the formula of compound interest we can make the following assumptions and calculate them for the same. You'll come across this formulae.........
Let us take it as "x" years and Total population to find be "Y" and let "PP" be as present population , we'll get this ,,,
Now, for population changes before "1" years ago, substitute this into "x" years ,,,
Therefore the answer is ,,,
