DIRECTION for the question: Solve the following question and mark the best possible option.

Five boys are standing in a row facing East. Deepak is to the left of Sameer, Tushar and Shailendra. Sameer, Tushar and Shailendra are to the left of Sushil. Shailendra is between Sameer and Tushar. If Tushar is fourth from the left, how far is Sameer from the right?

Deepak is to the left of Sameer, Tushar and Shailendra. Sameer, Tushar and Shailendra are to the left of Sushil.
These statements imply that Deepak is 1st from left and Sushil is 5th from left.
Shailendra is between Sameer and Tushar. This implies that he is 3rd from left.
The 2 possible arrangements are: Deepak Sameer Shailendra Tushar Sushil OR Deepak Tushar Shailendra Sameer Sushil.

If Tushar is fourth from the left, Sameer is also 4th from the right i.e. Option D.
