    The population after 144 years is 32,00,000.

    Explanation:

    Time , t = 48 years

    Current population, N₀ = 400,000

    Population in 144 years  = ?

    We first need to find the doubling time.

    Doubling time period , n = 144 / 48

    n = 3

    To find the population after a certain period of time, we use the formula

    N = N₀ X 2ⁿ

    N = 400,000 X 2³

    N = 32,00,000

    Therefore, the population after 144 years is 32,00,000.
