The reflection coefficient at source end is ((200-100)/(200+100))=(1/3),
so voltage become (90/3)=30,
reflection coefficient at load end is ((25-100)/(25+100))=(-3/5),
so reflected voltage (30*(-3/5))=-18v.

90(200-100/200+100)=90(1/3)=30.
30 is reflected voltage.
30 is reflected voltage.

I believe you need to divide the voltage first:
90(100/200+100)=30.
Then multiply it with the reflection coefficient
30*-0.6= -18.
90(100/200+100)=30.
Then multiply it with the reflection coefficient
30*-0.6= -18.

Calculate the output voltage to the reflected voltage.
For that reflected voltage you will get 27 tends to 30 and then do the further calculation.

How 30 came here? Please explain that.
