Step-by-step explanation:

The future population is calculated by $A=P(1+i)^{n}$ where A is projected population, P is present population, i is interest rate in decimal and n is duration in years.

$84000=42000(1+0.16)^{n}\\n=\frac {log 2}{log 1.16}=4.6701735389888214612132532241097152772246\approx 4.67 years$
