60%-60 is mango trees
Then,40% +60 is guava trees
If 15% of the trees is 60 trees then, 1% will be 4 trees.
Then,100% will be 100*4 trees =400 trees

Answer 2

Answer:

400

Step-by-step explanation:

Given = 60% trees are mango trees

Rest i.e., 40% trees are Guava trees.

Let the total number of trees be 100x

∴Mango trees = 60x

∴Guava trees = 40x

Now, 60 mango trees are cut down

60x - 60

Also, 60 guava trees are planted

40x + 60

Now, percentage of mango trees are 45%

Therefore,

(60x-60)/100x = 45/100

Solving, we get

60x - 60 = 45x

15x = 60

∴

100x = 400
