1) 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 .
2) find the compound intrest if the amount of a certain principal after two years is rs.4036.80 at the rate of 16 P.C.P.A .
3) A principal amounts to rs.13924 in 2 years by compound intrest at 18 P.c.p.a find the principal .
plz answer the all question with solution .....

Total trees in forest = 40000
A. T. Q
Trees increase per year = 40000x5/100 = 2000 trees in 1 year
In 3 years trees = 3x2000
=6000
Total trees after 3 years in forest
= 6000 + 40000
= 46000 trees is ans.

1) Principal amount = 40,000
Time = 3 years
Rate = 5%
CI = 40,000( 1+5/100)^3
= 40,000(21/20)^3
40,000*9261/8000
= 5* 9261
= 46,305
So the number of trees at the end of three years would be 46,305
Time = 3 years
Rate = 5%
CI = 40,000( 1+5/100)^3
= 40,000(21/20)^3
40,000*9261/8000
= 5* 9261
= 46,305
So the number of trees at the end of three years would be 46,305
