The population of a town increases by 5% every year. If the present population of the town is 282240, then what was the population of the town 2 years ago?
Answer & explanation
Correct answer: option 2
5% = \(\frac{1}{20}\)
Let population 2 years ago = P
According to question,
P × \(\frac{21}{20}\) × \(\frac{21}{20}\) = 282240
P = 282240 × \(\frac{20}{21}\) × \(\frac{20}{21}\)
= 256000
