IPMAT Indore 2022 - QA (MCQ) Q41 Q42 Q43 Q44 Q45 Explanation

Explanation:

Hint [41-45]:

Statement number 4 in the common data, actually tells us that Cathy does not work on Monday and Saturday.

So, arranging the given data in the table, we get

Let us denote Alex ⇒ A | Bhabha ⇒ B | Cathy ⇒ C | Dilip ⇒ D | Ethan ⇒ E

Also note, in this question, we need to consider Sun – Mon as pair of consecutive days because the showroom is open on all 7 days of the week.

Step 1: A and D works together on Tue & Wednesday. It means no other person will work on these 2 days. Also, they both must not be working on Monday & Thursday.

Step 2: C does not work on either on Monday or Saturday. Means she will not work on Monday and Saturday.

Step 3: C is left with only 3 days. Thus she will work on these days i.e. Thursday & Friday (consecutive) & (third working day)

Step 4: It is given that C does not work with A on any day. It means A will not be working on Friday and Sunday as C is working.

Step 5: A must be working on Saturday as third day. B and D will not be working with him (Given). Thus E will definitely work on Saturday.

Step 6: On Monday A, C & D are not working means B & E will definitely & work on Monday.

Step 7: As E is working on Monday and Saturday, he cannot work on Thursday, because in that case he will not be working on 2 consecutive days.

Also he cannot work on Sunday because in that case he will work on 3 consecutive days.

So the only option left for him is Friday along with Monday & Saturday.

Step 8: It is evident from the table that only B, C and D will be working on Sunday.

This way the table is completed and we can answer all the questions.

41. (d) Bhabha and Cathy work together for 2 days.

42. (d) The consecutive days Ethan works on Friday & Saturday.

43. (c) Dilip and Ethan do not work together at all.

44. (b) Bhabha, Cathy and Ethan work on Sunday.

45. (a) One of the days Alex work on is Saturday
