The population of city X increased by 10% in year 2013 and 15% in year 2014. What is the approximate population of the city at the end of year 2014, if population of the city at the starting of year 2013 was 21,000?

A. 23000

B. 25000

C. 25500

D. 26000

E. 26500
Effective % change in population is \(10 + 15 + \frac{10*15}{100} = 25 + 1.5 = 26.50\)

Hence, Population at the end of year 2014 is \(\frac{126.50}{100}*21000\) ~ \(26500\), Answer must be (E)

Answer should be option E!

Which is Approx 26500.
