MATHEMATICS

1)If sum and product of zero's of a Quadratic polynomial are 1,1 respectively then its corresponding quadratic polynomial is

A) x²-x+1

B) x²+x+1

C) x²+x-2

D) x²-x+2

View Answer

A) x²-x+1
Explanation:If sum and product of zero's of a quadratic polynomial are 1, 1 respectively, then its corresponding quadratic polynomial is
We use the formula:
Quadratic polynomial = $x^2 - (\text{sum})x + \text{product}$

Given sum = 1, product = 1
So, polynomial = $x^2 - 1x + 1 = x^2 - x + 1$

2)If in the equation x+3y=10 the value of y is '4'then the value of x will be

A) 2

B) 2

C) 4

D) 5

View Answer

A) 2

3)√p+√q is an irrational number. Where P, q are

A) Even numbers

B) Prime numbers

C) Rational numbers

D) None

View Answer

B) Prime numbers
Explanation:√p + √q is irrational. Where p, q are
If p and q are positive prime numbers, then √p and √q are both irrational, and their sum is also irrational.

4)Which of the following is true?

A) Φ=0

B) n(Φ)=0

C) Φ={0}

D) n(Φ¹)=0

View Answer

B) n(Φ)=0
Explanation:Which of the following is true?
Φ (phi) is the empty set, not 0
n(Φ) = 0 is correct, it means the number of elements in the empty set is 0
Φ = {0} is false because {0} is a set with one element
n(Φ¹) is not standard notation

5)If A={a,b,c,d} then number of subsets of A are

A) 8

B) 12

C) 16

D) 20

View Answer

C) 16
Explanation:If A = {a, b, c, d}, then the number of subsets = 2ⁿ = 2⁴ = 16

6)The pair of equations 3x+4y=k and 9x+12y=6 has infinitely many solutions if k=

A) 3

B) 2

C) 6

D) 5

View Answer

B) 2
Explanation:Pair of equations has infinitely many solutions if they are multiples of each other.
Equations: 3x + 4y = k and 9x + 12y = 6
Multiply first equation by 3: 9x + 12y = 3k
To match second equation: 3k = 6 → k = 2

7)The base of common logarithm is

A) 2

B) 5

C) 10

D) 1

View Answer

C) 10
Explanation:The base of the common logarithm is always 10

8)The pair of equations $\frac32x+\frac53y=7$ , 9x-10y=12, represents the following

A) Parallel lines

B) No solution

C) Infinitely many solutions

D) One solution

View Answer

D) One solution
Explanation:(3/2)x + (5/3)y = 7 and 9x − 10y = 12

9)If the given lines 2x+ky-1 and 3x-5y=7 are parallel, then the value of k is

A) -7

B) $\frac{10}3$

C) -13

D) $-\frac{10}3$

View Answer

D) $-\frac{10}3$

Explanation:Two lines are parallel if their slopes are equal.
Convert both to slope-intercept form:
First line: 2x + ky = 1 → ky = −2x + 1 → slope = −2/k
Second line: 3x − 5y = 7 → −5y = −3x + 7 → slope = 3/5
Now equate: −2/k = 3/5 → cross-multiply: −10 = 3k → k = −10/3

10)The zero's of a quadratic polynomial 4y²+8y are

A) 0,4

B) 0,2

C) 0,8

D) 0,-2

View Answer

D) 0,-2
Explanation:4y² + 8y = 4y(y + 2) → Zeroes: y = 0 and y = −2
