if we consider the population as 100... after first year it will be 125 with an increase of 25%.... in the 2nd year due to an increase of another 25 % it will be 156.25.... in the 3rd year there is a decrease of 25% it will be reduced to 117.1875..... in 4th year due to decrease of 25 % it will be reduced to 87.89075 .. so when you compare the current population to previous population we have observed a decrease of 12 % population ..
