  1. Answer:


    33275


    Step-by-step explanation:


    After 1 years:


    No. of trees = 25000 + 10% of 25000


                       = 25000 + 2500


                       = 27500


    After 2 years:


    No. of trees = 27500 + 10% of 27500


                       = 27500 + 2750


                       = 30250


    After 3 years:


    No. of trees = 30250 + 10% of 30250


                       = 30250 + 3025


                       = 33275


    Or directly, use:


    No. of trees = 25000 x (1 + r)ⁿ


                       = 25000 x (1 + 10/100)³


                       = 33275
