198 days

suppose 'x' is initial size and 'n' is no. of days.

1st day increment in size of tree = (1/2)x
After 1st day , size of tree = x+(1/2)x= (3/2)x

2nd day increment in size of tree = (1/3)*(3/2)x=(1/2)x
After 2nd day , size of tree = (3/2)x+(1/2)x=2x

3rd day increment in size of tree =(1/4)*2x=(1/2)x
After 3rd day , size of tree = 2x+(1/2)=(5/2)x

It is clear that every day tree grows (1/2)x in size.

therefore , according to given condition

x+ (1/2)x*n=100x
n=198 days.
