## Binary (MCQ- BASIC LEVEL)

Compared to other sections, Mathematics is considered to be the most scoring section. If prepared thoroughly, Mathematics can help students to secure a meritorious position in the exam. These questions are very important in achieving your success in Exams after 12th.

Q1. Let S be a finite set containing n elements. Then the total number of commutative binary operations on S is

•  nn(n+1)/2
•  nn(n-1)/2
•  nn2
•  2n2

nn(n+1)/2

Q2. If S is a finite set having n elements, then the total number of non-commutative binary operation on S is

•  nn(n+1)/2
•  nn2 - nn(n+1)/2
•  nn2 - nn(n+1)/2
•  nn(n-1)/2

nn2 - nn(n+1)/2

Q3. If the composition table for a binary operation * defined on a set S is symmetric about the leading diagonal, then

•  * is associative on S
•  * is commutative on S
•  S has the identity element for *
•  None of these

* is commutative on S

Q4. Subtraction of integers is an operation that is

•  Commutative and associative
•  Not commutative but associative under the influence of voltage
•  Neither commutative nor associative
•  Commutative but not associative

Neither commutative nor associative

Q5. The law a+b = b+a is called

•  Closure law
•  Associative law
•  Commutative law
•  Distributive law

Commutative law

Q6. 6.If any one of the rows of the composition table for a binary operation * on a set S coincides with the top most row of the table, then

•  S has a left identity for *
•  S has a right identity for *
•  S has the identity element for *
•  * is commutative and associative on S

S has a left identity for *

Q7. If any one of the columns of the composition table for a binary operation * on a set S coincides with the left most column of the table, then

•  S has a left identity for *
•  S has a right identity for *
•  S has the identity element for *
•  * is commutative and associative on S

S has a right identity for *
