(ii) Find the quadratic polynomial whose sum and product of zeroes are \(\frac{21}{8}\) and \(\frac{5}{16}\) respectively. (1)
Answer:
Sum of zeroes = α + β = \(\frac{21}{8}\)
And product of zeroes = α × β = \(\frac{5}{16}\)
So, the required quadratic polynomial is:
= x2 – (α + β)x + αβ
= x2 – \(\frac{21}{8}\)x + \(\frac{5}{16}\)

(iii) If α and β are zeroes of a polynomial x2 – 2√3x + 5 then find the value of α + β + αβ
Answer:
Let p(x) = x2 – 2√3x + 5
Since, α and β are zeroes of p(x), then α + β = sum of zeroes = \(\frac{-(-2 \sqrt{3})}{1}\) = 2√3
And α × β = product of zeroes = \(\frac{5}{1}\) = 5
Now, α + β + αβ = 2√3 + 5.

(iv) Two rails are represented by the equations x + 2y – 4 = 0 and 2x + 4y – 12 = 0. Will the rails cross each other ? (1)
Answer:
RBSE 10th Maths Model Paper Set 5 with Answers in English 1
This is the condition for parallelism. So, the given two rails will not cross each other.

(v) Write the discriminant of the quadratic equation (x – 5)2 = 2(5x + 3) (1)
Answer:
The given equation is
(x – 5)2 = 2(5x + 3)
⇒ x2 – 10x + 25 = 10x + 6
⇒ x2 – 10x – 10x + 25 – 6 = 0
⇒ x2 – 20 + 19 = 0
Here, a = 1, b = – 20 and c = 19
Discriminant = b2 – 4ac
= (-20)2 – 4 x 1 x 19
= 400 – 76 = 324

(vi) Find the discriminant of the quadratic equation 2x2 – 4x + 3 = 0 and hence find the nature of its roots. (1)
Answer:
The given equation is :
2x2 – 4x + 3 = 0
Here,
a = 2, b = – 4, c = 3
∴ D = b2 – 4ac
⇒ D = (- 4)2 – 4 × 2 × 3
⇒ D = 16 – 24
⇒ D = – 8
D < 0.
So, the given equation has no real roots.

Answer:
According to question
= \(\frac{5+y}{2}\)
⇒ 6 = 5 + y
⇒ y = 6 – 5 = 1
Coordinates of point is (- 5, 1).
Length of AB = \(\sqrt{(-5+2)^{2}+(1-5)^{2}}\)
= \(\sqrt{(-3)^{2}+(-4)^{2}}\)
= \(\sqrt{9+16}\) = √25 = 5
Hence, length of AB = 5 units

(ix) Solve for x, where 0° < x < 90°: 2 cos2θ = \(\frac{1}{2}\)
Answer:
We have, 2 cos2θ = \(\frac{1}{2}\)

Question 4.
Show that 5 – √3 is an irrational number.
Answer:
Let us assume, that 5 – √3 is a rational number. It can be expressed in the form of \(\frac{a}{b}\), where a and b are coprime positive integers and b ≠ 0.
∴ 5 – √3 = √3
[HCF of a and b is 1 and b ≠ 0]
⇒ √3 = rational number.
But this contradicts the fact that √3 is an irrational number. So, our assumption that 5 – √3 is a rational number, is wrong.
Hence, 5 – √3 is an irrational number.

Question 5.
If α, β and γ are the zeroes of the cubic polynomial 8x3 + x2 – 3x + 1, then find the value of α-1 + β-1 + γ-1. (2)
Answer:

Question 6.
A father’s age is three times the sum of the ages of his two children. After 5 years his age will be two times the sum of their ages. Find the present age of the father. (2)
Answer:
Let the age of father be x years and the sum of ages of his children be y years.
According to questions,
x = 3y ….(1)
After 5 years
Age of father = (x + 5) years And sum of ages of his children = (y + 10) years
According to the question,
x + 5 = 2(y + 10)
⇒ x + 5 = 2y + 20
⇒ x – 2y = 20 – 5
⇒ x – 2y = 15 ….(2)
From equation, (1), substituting the value of x in the equation, we get
3y – 2y = 15
⇒ y – 15 years
Putting the value of y in the equation we get
x = 3 × 15 = 45 years
Hence, present age of father = 45 years.

Question 7.
Find k so that the quadratic equation (k + 1) x2 – 2 (k + 1) x + 1 = 0 has equal roots. (2)
Answer:
(k + 1)x2 – 2(k + 1) x + r = 0
Since, equation has equa1 roots
∴ D = 0
⇒ b2 — 4ac = 0
⇒ [- 2(k + 1)]2 – 4 × (k + 1) × 1 = 0
⇒ 4(k2 + 2k + 1) – 4k – 4 = 0
⇒ 4k2 + 8k + 4 – 4k – 4 = 0
⇒ 4k2 + 4k = 0
⇒ 4k(k + 1)= 0 and k + 1 = 0
⇒ k = – 1
k = – 1 (Reject since if we put the k = – 1 in the equation (- 1 + 1)x will be zero
∴ k = 0

Question 8.
If second and third terms of an AP are 3 and 5 respectively, then find the sum of first 20 terms of it. (2)
Answer:
Let a be first term and common difference be d of an AP.
a2 = 3
⇒ a + d = 3 ….(1)
And a3 = 5
⇒ a + 2d = 5 ….(2)
Substracting equ. (2) from equ. (1), we get
RBSE 10th Maths Model Paper Set 5 with Answers in English 5
Substituting the value of d in equ (1), we get
a + 2 = 3
⇒ a = 1
Sum of first 20 terms is
S20 = \(\frac{20}{2}\) [2 × 1 + (20 – 1) × 2]
= 10 [2 + 38]
= 10 × 40 = 400
Hence, S20 = 400

Question 9.
For what value of n are the nth terms of two APs : 63, 65, 67 and 3, 10, 17…….. are equal ? (2)
Answer:
The two APs are 63, 65, 67, ………. and 3, 10, 17,
Let a, d and A, D be Ist term and common difference of two given APs.
Here, a = 63, d = 65 – 63 = 2
And A = 3, D = 10 – 3 = 7
nth terms of two APs are equal
an = An
⇒ a + (n – 1 )d = A + (n -1)D
⇒ 63 + (n – 1) × 2 = 3 + (n – 1) × 7
⇒ 63+ 2n- 2 = 3 + 7n – 7
⇒ 2n + 61 = 7n – 4
⇒ 61 + 4 = 7n – 2n
⇒ 65 = 5 n
⇒ n = \(\frac{65}{5}\) = 13
Hence, 13th term of two given APs are equal.

Question 12.
If cos 4A = sin (A – 50°), where 4A is an acute angle, find the value of A. (2)
Answer:
We have,
cos 4A = sin (A — 50°)
⇒ cos 4A = cos [90° – (A – 50°)] [∵ sin θ = cos (90° – θ)]
⇒ 4A = 90° – (A – 50°)
⇒ 4A = 90° – A + 50°
⇒ 4A + A = 90° + 50°
⇒ 5A = 140°
⇒ A = \(\frac{140^{\circ}}{5}\) = 28°.
Hence, A = 28°.

Question 13.
If x = a sin θ and y = b tan θ, ithen prove that \(\frac{a^{2}}{x^{2}}-\frac{b^{2}}{b^{2}}\) = 1
Answer:

= \(\frac{a^{2}}{a^{2} \sin ^{2} \theta}-\frac{b^{2}}{b^{2} \tan ^{2} \theta}\)
= \(\frac{1}{\sin ^{2} \theta}-\frac{1}{\tan ^{2} \theta}\)
= cosec2 θ – cot2θ = 1
= RHS

Question 14.
Find the mode of the following data: (2)
RBSE 10th Maths Model Paper Set 5 with Answers in English 8
Answer:
The class interval 60 – 80 has maximum frequency. So, it has modal class.
∴ l = 60, f1 = 24, f0 = 10, f2 = 6, h = 20
mode = \(l+\left(\frac{f_{1}-f_{0}}{2 f_{1}-f_{0}-f_{2}}\right) \times h\)
= \(60+\left(\frac{24-10}{2 \times 24-10-6}\right) \times 20\)
= 60 + \(\frac{14 \times 20}{48-16}\)
= 60 + \(\frac{280}{32}\)
= 60 + 8.75
= 68.75

Question 15.

RBSE 10th Maths Model Paper Set 5 with Answers in English 9
Find the mean daily pocket allowance by using appropriate method.
Answer:
RBSE 10th Maths Model Paper Set 5 with Answers in English 10
∴ Mean = \(\frac{\Sigma f_{i} x_{i}}{\Sigma f_{i}}\)
= \(\frac{955}{25}\) = ₹ 38.20
Hence, mean daily pocket allowance
= ₹ 38.20

Question 16.
A bag contains 5 red balls and some blue balls. If the probability of drawing a blue ball is double that of a red ball, determine the number of blue balls in the bag. (2)
Answer:
Let the number of blue balls in the bag be x.
Then total number of balls = (5 + x)
∴ Total number of possible outcomes = (5 + x)
∴ P(a blue ball) = \(\frac{x}{(5+x)}\)
∴ P(a red ball) = \(\frac{5}{5+x}\)
According to question P (a blue ball) = 2 × P(a red ball)
⇒ \(\frac{x}{(5+x)}\) × \(\frac{5}{5+x}\)
⇒ x = 10.
Hence, number of blue balls in the bag = 10.

Question 17.
The first term of an AP is 5, the last term is 45 and the sum is 400. Find the number of terms and the common difference. (3)
Or
Find the sum of first 22 terms of an AP in which d -‘1 and 22nd term is 149. (3)
Answer:
We have, a = 5, l = an = 45,
Sn = 400
⇒ \(\frac{n}{2}\) [a + l] = 400
⇒ \(\frac{n}{2}\) [5 + 45] = 400
⇒ n × 50 = 400 × 2
⇒ 50n – 800
⇒ n = \(\frac{800}{50}\)
⇒ n = 16
Now, an = 45
⇒ a + (n – 1 )d = 45
⇒ 5 + (16 – 1)d = 45
⇒ 5 + 15 d = 45
⇒ 15d = 45 – 5 = 40
⇒ d = \(\frac{40}{15}\) = \(\frac{8}{3}\)
Hence, n = 16, d = \(\frac{8}{3}\).

Question 18.

RBSE 10th Maths Model Paper Set 5 with Answers in English 11
By section formula, we have
RBSE 10th Maths Model Paper Set 5 with Answers in English 12
Hence, co-ordinates of required point, are (7, 3).

Question 19.
If sin θ + cos θ = √2 . Prove that : tan θ + cot θ = 2.
Or
Prove that: (1 – sin θ + cos θ)2 = 2 (1 + cos θ) (1 – sin θ).
Answer:
We have,
sin θ + cos θ = √2
(sin θ + cos θ)2= (√2)2
Squaring on both sides
⇒ sin2 θ + cos2θ + 2 sin θ cos θ = 2
⇒ 1 + 2 sin θ cos θ = 2
⇒ 2 sin θ cos θ = 1
⇒ sin θ cos θ = 2 N
Now, LHS = tan θ + cot θ
= \(\frac{\sin \theta}{\cos \theta}+\frac{\cos \theta}{\sin \theta}\)
= \(\frac{\sin ^{2} \theta+\cos ^{2} \theta}{\sin \theta \cos \theta}\) = \(\frac{1}{\sin \theta \cos \theta}\)
= \(\frac{1}{\frac{1}{2}}\) = 2 = RHS
LHS = RHS (Hence Proved)

RBSE 10th Maths Model Paper Set 5 with Answers in English 15
From the table, we have
Σfi = 25, Σfiui = – 7, a = 225, h = 50
∴x̄ = a + \(\left(\frac{\Sigma f_{i} u_{i}}{\Sigma f_{i}}\right)\) × h
⇒ x̄ = \(\left(-\frac{7}{25}\right)\) × h
⇒ x̄ = 225 – 14
⇒ x̄ = 211
Hence, the mean daily expenditure on food = ₹ 211.

Question 21.
The cost of 2 kg of apples and 1 kg of grapes on a day was found to be ₹ 160. After a month, the cost of 4 kg of apples and 2 kg of grapes is ₹ 300. Represent the situation algebraically and graphically. (4)
0r
Form the pair of linear equations in the following problems, and find their solution graphically. (4)
“10 Students of of class X took part in a Mathematics quiz. If the number of girls is 4 more than the nubmer of boys, find the number of boys and girls who took part in the quiz.”
Answer:
Let the cost of 1 kg apples be ₹ x and cost of 1 kg of grapes be ₹ y.
According to question,
2x + y = 160 … (1)
and 4x + 2y = 300
⇒ 2x + y = 150 …(2)
For representation of these equations graphically, we draw the graphs of these equations as follows:
2x + y = 160
⇒ y = 160 – 2x
We put the different values of x in this equation, then we get different values of y and we prepare the table of x, y for the equation 2x + y – 160.

Now, 2 x + y = 150
⇒ y – 150 – 2x
We put the different values of x in this equation then we get different values of y and we prepare the table of x, y for the equation 2x + y = 150.

4. Join OP and bisect it at M.
5. with M as the centre and radius PM = MO, draw another circle which intersect previous circle at R and Q.
6. Join PR and PQ. Then PR and PQ are the required tangents.
Justification: Join OR,
∠PRO= 90°
[Angle in a semi circle is 90°]
PR ⊥ OR
OR is a radius and PR is a tangent.
Similarly, PQ is a tangent.
