The population of a town increases every year by 4%. If population was 50000 in starting, then after two years will be :
A. 53900
B. 54000
C. 54080
D. 54900
Answer: Option C
Solution(By Examveda Team)
4% = $$\frac{1}{25}$$\[\begin{gathered} {\text{Initial }}\,\,\,\,\,\,{\text{Final}} \hfill \\ \,\,\,25\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,26 \hfill \\ \,\,\,25\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,26 \hfill \\ \overline {\,\,\,\,\,625\,\,\,\,\,\,\,\,\,\,\,676\,\,\,} \hfill \\ \end{gathered} \]
According to the question,
625 units = 50000
1 unit = $$\frac{50000}{625}$$ = 80
676 units = 80 × 676 = 54080
Hence, population after two years = 54080
