Six persons Ishi, Jolly, Kitty, Dinky, Emi and Ferry sit in a row facing North, but not necessarily in the same order. Who sits at the right end of the row?

I. Jolly sits exactly between Dinky and Ishi, who sits exactly between Kitty and Ferry. Kitty does not sit at any end of the row but sits to the immediate right of Ishi.

Dinki/Ishi Jolly Dinki/Ishi

Kitty/Ferry Ishi Kitty/Ferry

Ishi Kitty

we can not arrange....so statement I is not sufficient to answer the question.

II. There are exactly two persons sitting between Kitty and Ferry, who sits to the left of Ishi. Dinky sits to the immediate right of Kitty and is to the immediate left of Jolly.

Kitty/Ferry _ _ Kitty/Ferry

Ferry Ishi

Kitty Dinky Jolly Ferry Ishi

So, Ishi sits at the right end...

Hence, only statement II is sufficient to answer the question.
