Step-by-step solution
Seven cars stand in a row facing towards north direction. These cars are of seven different colors viz. Red, Black, Grey, Pink, White, Blue and Orange. No two cars are of same color.
Which car is standing at the estreme right end?
Statement I:& Red car is third to the left of Pink car, which is third from right end. Black car is on the immediate left of White car, which is adjacent to Pink car.&
Statement II:& & White car is second to the left of Grey car. Red car is on the immediate right of Orange car, which is at extreme left end.
Checking statement I:
As per the given hints, following arrangement can be prepared.
Which car is standing at the estreme right end?
Statement I:& Red car is third to the left of Pink car, which is third from right end. Black car is on the immediate left of White car, which is adjacent to Pink car.&
Statement II:& & White car is second to the left of Grey car. Red car is on the immediate right of Orange car, which is at extreme left end.
Checking statement I:
As per the given hints, following arrangement can be prepared.
| Red car& | Black car& | & White car | Pink car& |
Thus,the car at extreme right end cannot be determined.
Hence data in statement I is not sufficient to answer the question.
Checking statement II:
As per the given hints, following case is possible.
| & Orange car | & Red car |
Thus,the car at extreme right end cannot be determined.
Hence data in statement II is not sufficient to answer the question.
Checking statements I and II:
As per the given hints, following arrangement can be prepared.
| Orange car | Red car& | Black car& | & White car | Pink car& | Grey car | Blue car |
Thus Blue car is at extreme right end.
Thus both statements I and II is necessary to answer.
Hence option D is correct.
