The population of a town 2 years ago was 8000. If the population growth rate is 30% per annum. What will the population after 1 year ?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 17576.

The compound growth P =P0×(1+r)t P_0 \times (1 + r)^t

  • P0 = 8000 (initial population 2 years ago)

  • r = 30% = 0.30 (growth rate)

  • t = 3 years 

P=8000×(1+0.30)3=8000×(1.30)3P = 8000 \times (1 + 0.30)^3 = 8000 \times (1.30)^3

P=8000×2.197=17,576P = 8000 \times 2.197 = 17,576

Population after 1 year from will be approximately 17,576.
