Question 49
EasyOriginal questionSeven friends, Gauri, Hriday, Ira, Jatin, Kiran, Lakshmi and Mohit, each visit a science museum on a different day of one week. The week runs from Monday to Sunday, and exactly one friend visits on each day. 'Before' or 'after' means on any earlier or later day; 'immediately before' or 'immediately after' means the previous or the next day. The following is known:
1. Exactly three friends visit before Mohit.
2. Hriday visits on the last day of the week.
3. Gauri visits on the day immediately before Mohit.
4. Exactly one friend visits between Ira and Gauri.
5. Kiran visits on the day immediately after Ira.
6. Lakshmi visits before Gauri, but not on Monday.
After Lakshmi's visit, how many of the friends are still to visit the museum that week?
Show the answer and explanation
Correct answer: D
Explanation
Three friends visit before Mohit, so Mohit visits on Thursday; Gauri is on Wednesday (clue 3) and Hriday on Sunday (clue 2).
Lakshmi is before Gauri but not on Monday, so Lakshmi visits on Tuesday (clue 6).
Lakshmi visits on Tuesday; Wednesday to Sunday are five days, so 5 friends visit after her.
