Iift 2013 Question 20

c The professor from Jupiter published in 8 journals less than the professor from Pluto but donated to 10 more institutions last year.
We know Pluto donated to 8 institutes last year and has published in 12 journals. Thus, the professor from Jupiter published in 4
journals and donated to 18 institutes.
The professors from Mercury and Jupiter do not stay in room number 206.
Thus, the professor from Jupiter has to stay in either 202 or 204.
But the professor in room no. 202 has published 24 journals which is not the case with the professor from Jupiter.
Thus, the professor from Jupiter has to stay in room 202.
The professor from Uranus and the Professor in room number 206 together published in a total of 40 journals.
From this we can say that the professor from Uranus is not staying in room 206 and thus is staying in room no 204.
Thus, the professor from Neptune is staying in room no. 206.
The professor from Uranus has published papers in 24 journals and thus, the professor from Neptune has published papers in 16 journals.
The professor who published in 16 journals donated to 24 institutions last year.
Thus, the professor from Neptune has donated to 24 institutes last year.
Thus, the final table is:-

Thus, the professor from Mars is staying in Room 204.
Hence, option C is the correct answer.
