Q3 of 13 Page 93

In a forest there are 40,000 trees. Find the expected number of trees after 3 years if the objective is to increase the number at the rate 5% per year.

Present Trees (P) = 40000 trees, Rate = 5% (p.c.p.a), Duration (n) = 3 years



3


A = 40000 (1+0.05)3


A = 40000 (1.05)3


A = 40000 (1.157625)


∴A= 46305/-


∴ The expected number of trees after 3 years will be 46305.
