From 2011 to 2014, a town’s population is increasing at the rate of 2% annually. If its population was 13,265 in 2014, then what would have been its population (Approximately) in 2011?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 12500.
Calculations:
Let the population in 2011 be x
⇒ x × 102% × 102% × 102% = 13265
⇒ x × 102/100 × 102/100 × 102/100 = 13265
⇒ x = (13265 × 100 × 100 × 100)/(102 × 102 × 102)
⇒ x = 12499.90 or 12500
