Tara has decided to- tutor biology for the summer and is trying to plan her schedule. She can meet with up to two students a day, Monday 'through Friday, and has three students, Anu, Bhupesh, and Chirag. She needs to arrange her schedule according to the following constraints:

II. No student meets with Tara twice in the same day.
III. Anu refuses to meet with Tara on Fridays.
IV. Chirag will never meet with Tara the day after Bhupesh has a lesson.
V. Anu and Chirag meet with Tara on the same day exactly once a week.
VI. If Anu meets with Tara on Monday, so does Bhupesh.

Answer: Option D.

	Monday	Tuesday	Wednesday	Thursday	Friday
Anu	Yes		Yes		No
Bhupesh	Yes
Chirag	No	No	Yes

If Bhupesh Comes on Wednesday,Thursday,Friday, then Chirag can not come on Thursday Friday but can come with Anu on Tuesdays and alone on Monday an Anu can come anywhere in between Wednesday and Thursday. Hence 4th is the correct Option.

Answer: Option A.

	Monday	Tuesday	Wednesday	Thursday	Friday
Bhupesh	✓				✓
Anu	✓		✓
Chirag	No	No	✓	✓
Dana		✓		✓	✓

 

	Monday	Tuesday	Wednesday	Thursday	Friday
Bhupesh	✓			✓
Anu		✓	✓
Chirag			✓		✓
Dana	✓	✓		✓	✓

From the above arrangements it can be seen that the Max. possible times that Dana can come is 4 times. Hence 1st Option

Answer: Option D.
Out of the four options, since Anu cannot come on Tuesdays and Wednesday so Chirag also can’t, also if Anu comes on Monday, Bhupesh has to come and there cannot be three students with Tara on the same day, so Thursday is the correct answer, i.e. 4th option

Answer: Option D.
The possible cases are as follows:
Case 1: Here Anu can come anywhere between Tuesday and Wednesday

	Monday	Tuesday	Wednesday	Thursday	Friday
Bhupesh		✓			✓
Anu				✓	×
Chirag	✓		×	✓

 

	Monday	Tuesday	Wednesday	Thursday	Friday
Bhupesh		✓			✓
Anu			✓	✓
Chirag			×	✓	✓

 

	Monday	Tuesday	Wednesday	Thursday	Friday
Bhupesh		✓			✓
Anu			✓	✓
Chirag		✓	×	✓

From the case above Chirag must come on Thursday in each case, hense 4th option.
