15% is the percentage of new trees in the forest now.
Step-by-step explanation:
The number of new trees planted = 20/100 * 2000
= 400 trees
The number of trees cut down = 10% of 2000
= 100 trees
Total number of trees after the plantation drive = 2000 + 400 = 2400 trees
Trees cut down = 100
Remaining trees = 2300
The percentage of new trees in the forest now = 2300 - 2000/2000 * 100
= 15%
