Question 47
HardOriginal questionSix friends, Gurpreet, Hema, Irfan, Jasmine, Kiran and Lalit, sit around a circular table with equally spaced seats. Some of them face the centre and the others face outward, away from the centre.
1. Gurpreet faces the centre and sits opposite Jasmine.
2. Hema sits immediately to the left of Gurpreet.
3. Irfan faces outward and sits second to the right of Hema.
4. Both immediate neighbours of Jasmine face outward.
5. Lalit sits next to Hema.
6. Kiran sits immediately to the left of Jasmine.
How many of the six friends face the centre of the table?
Show the answer and explanation
Correct answer: C
Explanation
Facing the centre, left = next seat clockwise; facing outward, left = next seat anticlockwise (seen from above). Gurpreet faces the centre, so Hema is the next seat clockwise from him; Jasmine is opposite him.
Irfan is second to Hema's right. If Hema faced outward, her right would be clockwise and Irfan would land on Jasmine's seat. So Hema faces the centre and Irfan is two seats anticlockwise of her: the seat just anticlockwise of Gurpreet.
Lalit sits next to Hema: the seat between Hema and Jasmine. Kiran takes the seat after Jasmine. Clockwise from Gurpreet: Gurpreet, Hema, Lalit, Jasmine, Kiran, Irfan.
Lalit and Kiran face outward (clue 4). Kiran is the next seat clockwise from Jasmine and is on her left, so Jasmine faces the centre.
Facing the centre: Gurpreet, Hema and Jasmine, 3 people. Irfan, Lalit and Kiran face outward.
Worth noting
2 misses that clue 6 fixes Jasmine's direction; if she faced outward, her left would be Lalit, not Kiran.
