Q:

Statement: There was a spurt in criminal activities in the city during the recent festival season.
Courses of action:
a. The police should immediately investigate into the causes of this increase.
b. In future the police should take adequate precaution to avoid recurrence of such situation during festival.
c. The known criminals should be arrested before any such season.

A) Both a and b follows B) Only c follows
C) Only a follows D) Both b and c follows
 
Answer & Explanation Answer: A) Both a and b follows

Explanation:

The police ought to find out the lackenings in existing security arrangements and make up for these inadequacies to strengthen security and thus prevent criminal activities in the forthcoming festival. So, both a and b follow. Arresting the known criminals does not ensure safety, for a novice can also indulge in crime. So, c does not follow.

Q:

In an objective competitive exam, a correct answer score 4 marks and on a wrong answer 2 marks are negatively added. A student scores 420 marks from 150 question. How many answers were correct ?

A) 145 B) 138
C) 125 D) 120
 
Answer & Explanation Answer: D) 120

Explanation:

let x be the correct answer and y be the wrong answer
so the total number of questions is (x + y) = 150.....(1)
=> 4x - 2y = 420.....(2)
By solving (1) & (2), we get
=> 6x = 720
hence x = 120
Therefore, number of correct answers are 120.
