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?
Answer & explanation
Correct answer: option 3
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.
