Q.1: The smallest number which when divided by 28 and 42 leaves remainders 8 and 22 respectively is:
(a) 104
(b) 84
(c) 64
(d) 74

Correct Answer is Option (c)

∵ 28 – 8 = 20 and 42 – 22 = 20

Now, 28 = 22 × 7

and 42 = 2 × 3 × 7

∴ LCM (28, 42) = 22 × 3 × 7

= 84

Required number = LCM (28, 42) – 20

= 84 – 20

= 64.


Q.2: If tan θ – cot θ = 8, then the value of tan2θ + cot2θ is:
(a) 68
(b) 69
(c) 66
(d) 70

Correct Answer is Option (c)

Given,

tan θ – cot θ = 8

Taking square on both sides, we get

tan2 θ + cot2 θ – 2 tan q . cot θ = 64

Here,
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 3 Notes | Study CBSE Sample Papers For Class 10 - Class 10

So, DE || BC   [By the converse of Thales theorem]

∴ ∠AED = ∠ACB

(corresponding angles)

But ∠AED = ∠ABC (given)

∴ ∠ABC = ∠ACB.


Q.4: In a given DABC, DE || BC and AB/DB = 3/4. If AC = 4.9 cm, then AE is :
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 3 Notes | Study CBSE Sample Papers For Class 10 - Class 10

(a) 2.5 cm
(b) 2.8 cm
(c) 2.1 cm
(d) 2.6 cm

Correct Answer is Option (c)

Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 3 Notes | Study CBSE Sample Papers For Class 10 - Class 10

Let AE = x cm,

then EC = (4.9 – x) cm

and DE || BC (given)
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 3 Notes | Study CBSE Sample Papers For Class 10 - Class 10

⇒  3(4.9 – x) = 4x

⇒  14.7 – 3x = 4x

⇒  7x = 14.7

⇒  x = 2.1


Q.5: If p(– 3) = 0, then one factor of the polynomial p(x) is:
(a) x – 3
(b) x + 3
(c) 3x
(d) x/3

Correct Answer is Option (b)

∵ p(– 3) = 0

∴p(x) = x + 3.

Q.7: If the short and long hands of a clock are 5 cm and 6 cm long respectively, then the distance travelled by long hand in 60 hours is:
(a) 32π cm
(b) 28π cm
(c) 60π cm
(d) 96π cm

Correct Answer is Option (c)

∵ Long hand makes 5 rounds in 60 hours and radius of the circle formed by long hand = 6 cm
∴ Distance travelled by long hand in 5 rounds
= 5 × circumference of the circle
= 5 × 2πr
= 5 × 2π × 6
= 60π cm.

Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 3 Notes | Study CBSE Sample Papers For Class 10 - Class 10

Hence, the ratio of the corresponding sides is 9 : 11.


Q.17: The sum of the ages of a father and the son is 45 years. If father's age is four times that of his son, then son's age is:
(a) 7 years
(b) 8 years

(c) 9 years 
(d) none of these

Correct Answer is Option (c)

Let age of father and son be x and y respectively, then
x + y = 45 ...(i)

and x = 4y ...(ii)

Substituting x = 4y in eq. (i), we get

4y + y = 45

⇒ 5y = 45

⇒ y = 9


Q.18: If the distance between the points A(– 3, 2) and B(x, 10) is 10, then the possible values of x is:
(a) 3 and 9 
(b) - 3 and 9

(a) 46 
(b) 48
(c) 41
(d) 50

Correct Answer is Option (a)

Total oranges,

n(S) = 1000

Let the no. of bad oranges be x, then

n(E) = x

P(getting bad orange) = 0.046
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 3 Notes | Study CBSE Sample Papers For Class 10 - Class 10
⇒ x = 1000 × 0.046

⇒ x = 46.

In case of assertion:

p = a2 b3

and q = a3 b3

Then LCM (p, q) = a3 b3

and HCF (p, q) = a2 b3

∴LCM (p, q) × HCF (p, q)

= a3 b3 × a2 b3

= a5 b6.

⇒ θ = 45°


Q.24: 19 cards numbered 1, 2, 3, ....., 19 are put in a box and mixed thoroughly. A man draws a card from the box, then the probability (getting the no. on the card is odd) is:
(a) 9/19
(b) 8/19
(c) 7/19
(d) 10/19

Correct Answer is Option (d)

Total outcomes n(S) = 19

odd numbered cards = 1, 3, 5, 7, 9, 11, 13,

15, 17, 19

i.e., favourable outcomes

n(E) = 10

∴ P(getting a card is odd)

Q.25: One zero of the polynomial 2x3 - x2 - 13x - 6 is:
(a) -8
(b) 3
(c) -3
(d) 1

Correct Answer is Option (b)

Let p(x) = 2x3 – x– 13x – 6, then 3 is a

zero of p(x).

∴ p(x) = 0

i.e., p(3) = 2(3)3 – (3)2 – 13(3) – 6

= 2 × 27 – 9 – 39 – 6

= 54 – 9 – 45 = 0

Q.29: Mr. Shayam has recently shifted in his new house. When he entered in master bed room and observed its dimensions 8m × 6m × 4m. He decided to put one longest rod into it. The length of the longest rod will be.

Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 3 Notes | Study CBSE Sample Papers For Class 10 - Class 10

(a) 4 m 
(b) 6 m
(c) 2 m 
(d) 12 m

Correct Answer is Option (c)

Length = 8 m, breadth = 6 m and height = 4 m

Since, the length of the longest rod is equal to HCF (8, 6 and 4), i.e.,

8 = 23,

6 = 2 × 3

and 4 = 22

Then, HCF (8, 6 and 4) = 2

Thus, the longest rod that can measure

the dimensions of the room exactly = 2m.


Q.30: The value of 10 sec2 A – 10 tan2 A is:
(a) 9
(b) 10
(c) 11
(d) 12

Correct Answer is Option (b)

10 sec2 A – 10 tan2 A = 10 (sec2 A – tanA)

= 10 × 1

[∵ sec2 q – tan2 q =1]

= 10.

Q.31: The value of the quadratic polynomial f(x) = 2x2 - 3x - 2 at x = 1 is:
(a) - 2 
(b) - 1
(c) - 4 
(d) - 3

Correct Answer is Option (d)

Given,

f(x) = 2x2 - 3x - 2

Then, f(1) = 2(1)2 - 3(1) -– 2

= 2 - 3 - 2

= -3.


Q.32: In a lottery, there are 8 prizes and 16 blanks. The probability of getting a prize is:
(a) 1/2
(b) 2/3

(c) 1/3
(d) 5/3

Correct Answer is Option (c)

In case of assertion,

Total no. of lottery tickets

= 8 + 16 = 24
∴ P(getting a prize) = 8/24 = 1/3


Q.33: If one zero of the quadratic polynomial 5x2 + p(x) + 8 = 0 is 1/2, then the value of p is:
(a) 33/2
(b) 35/2
(c) - 37/2
(d) 41/2

Correct Answer is Option (c)

5x2 + p(x) + 8 = 0
∵ 1/2 is a zero, so it must satisfy the given equation,

Q.37: If one zero of the quadratic polynomial x2 – 3x – k is – 1, then the value of k is:
(a) 2 
(b) 3
(c) 4
(d) 6

Correct Answer is Option (c)

Let p(x) = x2 – 3x – k

∵ -1 is a zero of p(x), then

p(–1) = 0

∴ (-1)2 - 3(-1) - k = 0

⇒ 1 + 3 - k = 0

⇒ k = 4.


Q.38: If a chord of the circle of radius 8 cm subtends a right angle at the centre, then the area of sector OACBO is: (Use, p = 3.14)
(a) 50.24 cm2

Q.39: If x + 5 is a factor of p(x) = 2x3 – 4x2 + ax + 5, then the value of a is:
(a) - 4 
(b) - 3
(c) 4 
(d) 3

Correct Answer is Option (a)

x + 5 = 0

⇒ x = – 5

∴ 2(- 5)3 - 4(- 5)2 + a(- 5) + 5 = 0

⇒ 2 x (-125) - 100 - 5a + 5 = 0

⇒ - 350 + 5 = 5a

⇒ 5a = - 345

⇒ a = - 69


Q.40: If tan θ = cot θ, then the value of 2 tan θ + cos2 θ is:
(a) 1 
(b) 2
(c) 3 
(d) 5/2

Correct Answer is Option (d)

∵ tan θ = cot θ

Here tan 45° = cot 45°

= 1.

∴ θ = 45°

Now 2 tan θ + cos2 θ = 2 tan 45° + (cos45°)2

∠A + ∠C = 180°
⇒ 2x – 1 + 2y + 15 = 180°
⇒ x + y = 83 ...(i)
∠B + ∠D = 180°
y + 5 + 4x – 7 = 180°
4x + y = 182 ...(ii)
Subtracting eq. (i) from (ii), we get
3x = 99
⇒ x = 33.


Q.43: The prime factorisation of 13915 is
(a) 5x 113 x 132
(b) 5x 113 x 232

(c) 5x 112 x 23
(d) 5x 112 x 232

Correct Answer is Option (a)

∠B + ∠C = (y + 5)° + (2y + 15)°

= (3y + 20)°

= (3 × 50° + 20°)

= 170°.


Q.44: What will be the value of y?
(a) 23
(b) 22
(c) 11
(d) 19

Correct Answer is Option (b)

∠A + ∠D = (2x – 1)° + (4x – 7)°

= (6x – 8)°

= (6 × 33 – 8)°

[From question (i), x = 33]


Q.45: According to Fundamental Theorem of Arithmetic 13915 is a
(a) Composite number
(b) Prime number
(c) Neither prime nor composite
(d) Even number

Correct Answer is Option (c)

∠D = (4x – 7)°

= (4 × 33 – 7)°

= 125°.

Now, total area of bigger pizza

= 3 × area of one slice

= 3 × 20√39 cm2

= 60√39 cm2
