Q.1.
(a) How many vacancies existed for Senior scientists?
We know that in the written examination, there were two candidates for each vacancy of junior scientist. If the vacancies for senior and junior scientists are J and S respectively, we can say J+S = 50.
But 2J and S sat down for written examination => 2J+S=75
From the above two equations, we get J=25, so S=25....YES
(b) Had Allen scored more than Brian in post graduation?
We know for Junior scientists, at least 80% is required while for senior scientists at least 85% is required. However, we do not have any information to suggest that Brian did not score more than 85% or more than Allen…NO
(c) After four years, will Allen have more than two times the work experience in Company Z as compared to Brian, if both joined in respective posts at the same time?
We know Allen has served for 5 years in the company as Junior scientist for sure, so after 4 years, the time taken by Allen will be 9yrs minimum and by Brian 4 years. So the time of Allen is at least 9/4 or 2.25 times…YES
Q.2.
(a) Allen had a doctorate degree: We know Allen has been selected as Senior Scientist, for which a person should have worked as a junior scientist in the same company. The requirement of a Junior scientist in the company is to have a Doctorate degree. Hence Yes
(b) Brian had at least 2 years experience in a government job: The requirement for a Junior scientist is 2 years experience in a government job or 3 years experience in private. Hence we cannot be sure. Hence, No
(c) One-third of those who gave either of the written examinations were not selected for the applied posts
Out of 100 candidates, 25% did not meet the criteria, and hence only 75 candidates gave a written examination. We further know that 100% seats, that is 50 vacancies, were filled up. Thus 75-50 or 25, which is ⅓ of 75, did not get selected…YES
Q.3. We know that in the written examination, there were two candidates for each vacancy of junior scientist. If the vacancies for senior and junior scientists are J and S respectively, we can say J+S = 50.
But 2J and S sat down for written examination => 2J+S=75
From the above two equations, we get J=25, so S=25.
