IPMAT Indore 2023 - QA (MCQ) Q41 Q42 Q43 Q44 Q45 Explanation

Explanation:

Hint [41-45]:

We have been provided with following information.

i. Each drug works on at least one organism but not more than two organisms.

ii. Each organism can be treated with at least two and at most three of these five drugs.

iii. On whichever organism A works, B also works. Similarly, on whichever organism C works, D also works.

iv. D and E do not work on the same organism.

From point (iii), if A works on a particular organism then B we will also work on it. Also if C works on a particular organism then D we will also work on it.

From point (iv) if D works on a particular organism then E will not work on it.

We can conclude the following:

1) A works on R, so B must also work on R. Therefore B works on Q and R, so it cannot work on P. As B is not working on P, A would not have worked on it.

2) C works on Q, so D must also work on Q. As D works on Q, E will not work on it. As B, C and D three drugs working on Q, then two drugs A & E will not work on Q.

3) As A & B are not working on it, both C and D should work on P (E will not work on P, as D is working)

4) E is not working on P and Q. Means it must work on R (from point i, given in the question). A, B and E is working on R, means C and D must not be working on it (from point ii, given in the question).

This way we will be able to complete the table and answer the questions.
