Question

The refresher course will start with which one of the following subjects?

• A. Psychology
• B. Mechanics
• C. Philosophy
• D. Economics
• E. None of these

Answer 1

The correct option is A Psychology

22nd	23rd	24th	25th	26th	27th	28th	29th
Psychology Psychology	Sunday Sunday	Philosophy Philosophy	Economics Sociology	Science Economics	Engg. Science	Sociology Engg.	Mechanics Mechanics

Clearly, 22nd is Psychology. 23rd July is holiday. Philosophy is on 24th, just after holiday. 25th can't have engineering as science should be before it, and if it is science, there won't be a one day gap between Economics and Engineering. Thus, Economics is on 25th. Science is on 26th, just before Engineering on 27th. Thus, 28th becomes Sociology since the it ends on 29th with mechanics.
Another case is possible with Sociology coming before Economics-Science-Engineering. Such that Sociology on 25th, Economics-Science-Engineering on 26-27-28th.
