Seven people, Ritu, Sonu, Tanvi, Uma, Varsha, Wamiq and Yusuf, are sitting in a row, facing South. Uma sits in the middle of the row. Tanvi sits third to the right of Uma. Ritu sits second to the right of Wamiq. Yusuf sits at one of the ends of the row, and Sonu sits next to Yusuf.
How many people sit between Sonu and Tanvi?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 4
Left and right are the people’s own. Facing South, their left is towards the east. Number the seats 1 to 7 from their left end; the middle seat is seat 4.
Uma is in the middle: seat 4; Tanvi is third to the right of Uma: seat 7, the right end
Yusuf is at an end, and seat 7 is taken: Yusuf is in seat 1, and Sonu, next to him, in seat 2
Seats 3, 5 and 6 are left. Ritu is two seats to the right of Wamiq: Wamiq in seat 3 and Ritu in seat 5 (Wamiq in seat 5 would need seat 7, which is Tanvi’s, and seat 6 would need seat 8)
Varsha takes seat 6. Order from their left: Yusuf, Sonu, Wamiq, Uma, Ritu, Varsha, Tanvi
Between Sonu (seat 2) and Tanvi (seat 7) sit Wamiq, Uma, Ritu and Varsha: 4 people
