Question
If the population of a city increases by 20% every year
and is expected to be 43,200 after 2 years, then what is its present population?Solution
ATQ,
Let, the present population be ‘x’.
ATQ,
Future population after 2 years = 1.20 × 1.20 × x = 43200
Or, x = 43200 × (1/1.20) × (1/1.20)
So, x = 30,000
