Let's use this compass direction :

      E

N    •    S

     W

Instead of :

      N

W    •    E

      S

Coming to Question :

Five girls are standing in a row facing East.

Let 5 girls places be labeled as 1,2,3,4 and 5

1 │  2 │  3 │ 4 │ 5

→ Tulsa is fourth for left, so she in number 4

Then the places will be as follows :

1 │  2 │  3 │ Tulsa │ 5

→ Tulsa and Urmila are to the left of kumud. Only one slot (i.e. 5th slot) is left to the leftside of Tulsa, which will be filled by kumud, and the third slot by Urmilla. This statement becomes true according to the given hint. If we check Tulsa and Urmila , they will be to the left of kumud.Hence the positions are correct till now.

Then the places will be as follows :

1 │  2 │  Urmila │ Tulsa │ Kumud

Usha is also left to Kumud but doesn't get position in 3rd slot as if Usha gets 3rd slot, Savita will be left to Usha and Urmila needs to get 1st slot. This doesn't match our question hints. So Usha gets 2nd slot.

Then the places will be as follows :

1 │  Usha │  Urmila │ Tulsa │ Kumud

You may think why not 1st slot ?

Because if Usha gets 1st slot, there is no slot left to Usha and hence Savita position doesn't suit, hence it's incorrect

→ Savita is to the left of Usha.

Then the places will be as follows :

Savita │  Usha │  Urmila │ Tulsa │ Kumud

_____________________

Now we got positions of all five girls. Now we need to find Usha's position from right

Savita │ Usha │  Urmila │ Tulsa │ Kumud

  5             4            3            2              1            (Postions from right)

Hence Usha is fourth from Right
