At present, the number of trees in a village is 52,020. It increases annually at the rate of 2%. What was the number of trees in the village two years ago?

50,000

Population after 2 years = 52020

Let Population 2 years ago = x

According to question ,

x × \(\frac{102}{100}\) × \(\frac{102}{100}\) = 52020

x = 52020 × \(\frac{50}{51}\) × \(\frac{50}{51}\)

= 50,000

So , population 2 years ago is 50,000.
