Answer 1

Answer:QRUPTS

Explanation:

Answer 2

Either S or R can be on the extreme right.

• As given six cars are present so we have six spaces( all facing East).
• Two cars are there between U and S so we can write,

(I) U _ _ S

or

(ii) S_ _ U

• Also given that Q is on the extreme left, so we can write as-

(I) Q U _ _ S_ or Q _ U _ _ S

(ii) QS _ _ U_ or Q_ S_ _ U

• Also given that P is between T and U, so the probable arrangements can be-

(I) Q U P T S_ or Q _ U P T S

(ii) QS T P U_ or Q_ ST P U

• Also given that one car is between P and R,

(I) Q U P T S_ ( eliminated)

Q R U P T S

(ii) QS T P U R

Q_ ST P U ( eliminated)

So here we get two probably arrangements,

Q R U P T S and Q S T P U R.

Therefore, either S or R can be on the extreme right.
