Present population of a village is 67600, It has been increasing annually at the rate of 4%. What was the population of the village two years ago ?

Answer: Option A

Let the initial population = x
According to the question,
$$\begin{array}{rl}& x\times \frac{104}{100}\times \frac{104}{100}=67600\\ & x=\frac{67600\times 100\times 100}{104\times 104}\\ & =62500\end{array}$$
Hence required population = 62500
