Let the total no. of trees in 100x

60% are the mango trees. So, the number of mango trees = 60x 

30 mango trees were cut down. So, the remaining mango trees = 60x - 30 

As 30 cut down & 30 planted, so total trees left = 100x

Now, there are 45% of mango trees

So, 60x - 30 = 45x

15x = 30

x= 2

100x = 200

Hence, the number of total trees = 200
