Q:

Every rational number is an integer.

A) TRUE B) FALSE
Answer & Explanation Answer: B) FALSE

Explanation:

Any integer 'i' can be written as i = i/1, which is a rational number. Clearly, 7/2,-5/4, etc... are rational numbers but they are not integers.


Hence, from the above analysis, every integer is a rational number but a rational number need not be an integer.


 


Therefore the given statement that 'Every rational number is an integer' is FALSE.

Q:

6 divided by 2(1 + 2) =

A) 1 B) 0
C) 9 D) Can't be determined
 
Answer & Explanation Answer: C) 9

Explanation:

The given expression can be simplified as

÷ 2 (1 + 2)

The expression can be simplified further by the order of operations, using BODMAS rule.

 

First evaluate Parentheses/Brackets, then evaluate Exponents/Orders, then evaluate Multiplication-Division, and finally evaluate Addition-Subtraction.

 

Now, the expression becomes ÷ 2 (3)

 

According to the order of operations, division and multiplication have the same precedence, so the correct order is to evaluate from left to right. First take 6 and divide it by 2, and then multiply by 3.

6 ÷ 2 × 3

= 3 × 3

= 9

But not  6÷2×3 = 6 ÷ 6 = 1

Hence, 6 ÷ 2 (1 + 2) = 9.

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.
