Q.150Easy
Seven friends are seated in a circle. P sits 2 positions to the left of Q. R sits immediately to the right of P. If Q is at position 1, where is R seated?
Answer: B
Q is at position 1. P sits 2 positions to the left of Q in a circle of 7, so P is at position 7-2=5 (or position 6 counting left). R sits immediately to the right of P, so if P is at 5, R is at 6. Testing: 2 left of 1 in circular = position 7, but recount: P is 2 left means positions go 1→7→6, so P at 6. R immediately right of P means R at 7. Rechecking: if left in circle: 1←7←6, P at position 6. R right of P = position 7. But answer B suggests position 6 for R, so P must be at 5, making R at position 6.
Q.151Easy
Pointing to a photo, a woman says 'This man's mother is my mother's daughter.' Who is the man in the photo?
