Q.1: The smallest number which when divided by 26 and 32 leaves remainders 6 and 12 respectively is: 
(a) 416 
(b) 420 
(c) 396 
(d) 436

Correct Answer is Option (c)

∵ 26 – 6 = 20 and 32 – 12 = 20
Now,  26 = 2 × 13 and 32 = 2 × 2 × 2 × 2 × 2

∴ LCM (26, 32) = 25 × 13 = 416

Required number = LCM (26, 32) – 20 = 416 – 20

= 396.

Q.3: If the points P(2, 4) is equidistant from the points A(5, k) and B(k, 7), then the value of k is:
(a) 3
(b) 2
(c) 1
(d) – 3

Correct Answer is Option (a)

Distance of AP = Distance of BP
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10
⇒ (– 3)2 + (4 – k)2 = (2 – k)2 + (– 3)2
⇒ 16 + k2 – 8k = 4 + k2 – 4k
⇒ –4k = –12
⇒ k = 3.


Q.4: If 3x + y = 14 and 2x – y = 1, then the value of y is:
(a) 2
(b) 3
(c) 4
(d) 5

Correct Answer is Option (d)

3x + y = 14   ...(i)
and 2x – y = 1   ...(i)
On adding, 5x = 15
⇒ x = 3
Putting x = 3 in eq. (i), we get
9 + y = 14
⇒ y = 14 – 9 = 5.


Q.5: If the distance between the points (x, b) and (a, 0) is Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10 then the value of x is:

⇒ (a – x)2 + b = a2 + b2

⇒ a2 + x2 – 2ax = a2

⇒ x2 – 2ax = 0

⇒ x(x – 2a) = 0

⇒ x = 0, 2a.


Q.6: In the equation 2x + 3y = 13, if x is having a value 2, then corresponding value of y is
(a) 2
(b) 3
(c) 1
(d) 4

Correct Answer is Option (b)

Putting x = 2 in equation
2x + 3y = 13, we get
2 × 2 + 3y = 13
⇒ 3y = 13 – 4 = 9
⇒ y = 3.


Q.7: If (4, 10) is the mid point of the line segment joining (– 8, 13) and (x, 7), then x is equal to:
(a) 16 
(b) 10
(c) 8
(d) 4

Correct Answer is Option (a)

Here, x1 = – 8, y1 = 13

and x2 = x, y2 = 7

Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10

Comparing both sides, we get
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10

⇒ x – 8 = 8

i.e., x = 16.


Q.8: If the mid point of the line segment joining the points A(5, 4) and B(k, 8) is P(x, y) and 2x + 3y – 10 = 0, then the value of k is:
(a) 12
(b) – 12
(c) 13
(d) – 13

Correct Answer is Option (d)

Mid point of A (5, 4) and B(k, 8)

Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10

which is equal to P(x, y)
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10
∵  2x + 3y – 10 = 0
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10

⇒ 5 + k + 8 = 0

⇒ k = – 13.

Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10
Solving equation (i), we get result as 14/11.


Q.10:  If tan θ + cot θ = 7, then the value of tan2 θ + cot2 θ is:

(a) 48
(b) 49
(c) 47
(d) 46

Correct Answer is Option (a)

Given,

tan θ + cot θ = 7

Taking square on both sides, we get

tan2θ + cot2θ + 2 tan θ . cot θ = 49

⇒ tan2θ + cot2θ + 2 = 49
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10
⇒ tan2 θ + cot2 θ = 49 – 2 = 47.


Q.11: The area of circle that can be inscribed in a square of side 1.4 cm, is:
(a) 2.2 cm
(b) 1.82 cm
(c) 1.62 cm
(d) 1.54 cm2

Correct Answer is Option (d)

side of a square = diameter of the circle

∴ Radius of the circle (r) = 1.4/2

= 0.7 cm

Now, area of the circle = πr2

(c) 5/3
(d) 4/3

Correct Answer is Option (c)
Since x, x + y and x – y are zeroes of p(x).

∴ 3x = 5
⇒ x= 5/3


Q.37: If AB =9 cm, BC = 6 cm then AB2 + BC2 is:
(a) 115
(b) 118
(c) 117
(d) 121

Correct Answer is Option ()

Given, AB = 9 cm

and BC = 6 cm

Then, AB2 + BC2 = (9)2 + (6)2

= 81 + 36 = 117


Q.38: 3 group of children decided to calculate the length of park model designed by them for school project. The given below figure is as shown then what is the value of x ?
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10
(a) 35 cm
(b) 36 cm
(c) 37 cm
(d) 34 cm

Correct Answer is Option (d)

Since ABCD is a rectangle,
AB = CD
i.e., x + y = 50 ...(i)
and BC = AD
i.e., x – y = 18 ...(ii)
On adding eq. (i) and (ii), we get
2x = 68
⇒ x = 34 cm.


Q.39: If √3 is an irrational number, then 5√3 is a/an:
(a) rational number
(b) prime number

(c) odd number
(d) irrational number

Correct Answer is Option (a)

5√3 is not a rational number because the product of rational and irrational number is irrational


Q.40: If sin θ + cos θ = √3, then the value of sin θ cos θ is:
(a) 1
(b) - 1
(c) 2
(d) 3

Correct Answer is Option (c)
Given sin θ + cos θ = √3

On squaring both the sides, we get
sin2 θ + cos2 θ + 2 sin θ cos θ = 3
⇒ 1 + 2 sin θ cos θ = 3
⇒ 2 sin θ cos θ = 2
⇒ sin θ cos θ = 1.

The figure given alongside shows the path of a diver, when she takes a jump from the diving board. Clearly it is a parabola.
Annie was standing on a diving board, 48 feet above the water level. She took a dive into the pool. Her height (in feet) above the water level at any time ‘t’ in seconds is given by the polynomial h(t) such that h(t) = –16t² + 8t + k.

Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10

Q.41: Rita’s height (in feet) above the water level is given by another polynomial p(t) with zeroes –1 and 2. Then p(t) is given by-

(a) t² + t – 2
(b) t² + 2t – 1
(c) 24t² – 24t + 48
(d) – 24t² + 24t + 48

Correct Answer is Option (d)

t= –1 & t=2 are the two zeroes of the polynomial p(t)

Then p(t)=k (t– (–1))(t–2) = k(t +1)(t–2)

When t = 0 (initially) h1 = 48ft

p(0)=k(02– 0 –2)= 48

i.e. –2k = 48

So the polynomial is -24(t²- t -2) = -24t² + 24t + 48.


Q.42: The zeroes of the polynomial r(t) = – 12t² + (k – 3)t + 48 are negative of each other. Then k is
(a) 3
(b) 0
(c) – 1.5
(d) – 3

Correct Answer is Option (a)

When the zeros are negative of each other,
sum of the zeros = 0
Class 10 Mathematics: CBSE Sample Question Paper- Term I (2021-22) - 1 Notes | Study CBSE Sample Papers For Class 10 - Class 10


Q.43: What is the value of k?
(a) 0
(b) – 48
(c) 48
(d) 48/–16

Correct Answer is Option (c)

Initially, at t=0, Annie’s height is 48ft

So, at t =0, h should be equal to 48

h(0) = –16(0)² + 8(0) + k = 48

So k = 48


Q.44: A polynomial q(t) with sum of zeroes as 1 and the product as –6 is modelling Anu’s height in feet above the water at any time t( in seconds). Then q(t) is given by
(a) t² + t + 6
(b) t² + t – 6

(c) – 8t² + 8t + 48
(d) 8t² – 8t + 48

Correct Answer is Option (c)

A polynomial q(t) with sum of zeroes as 1

and the product as –6 is given by q(t) = k(t² - (sum of zeroes)t + product of zeroes)

= k(t² –1t + (–6)) ………..(1)
When t=0 (initially) q(0)= 48ft
q(0) = k(02–1 (0)–6)=48

i.e. –6k = 48 or k =–8

putting k=–8 in equation (1),

required polynomial is.

=–8 (t2–1t–6)

=–8 t2 + 8t +48


Q.45: At what time will she touch the water in the pool? 
(a) 30 seconds
(b) 2 seconds
(c) 1.5 seconds
(d) 0.5 seconds

Correct Answer is Option (b)

When Annie touches the pool, her height =0 feet

i.e. –16t² + 8t + 48 =0 above water level
2t² – t –6 = 0
2t² - 4t +3t -6 = 0
2t(t-2) +3(t–2) = 0
(2t +3) (t–2) = 0

i.e. t = 2 or t= –3/2

Since time cannot be negative , so t = 2 seconds

A hockey field is the playing surface for the game of hockey. Historically, the game was played on natural turf (grass) but nowadays it is predominantly played on an artificial turf. It is rectangular in shape - 100 yards by 60 yards. Goals consist of two upright posts placed equidistant from the centre of the backline, joined at the top by a horizontal crossbar. The inner edges of the posts must be 3.66 metres (4 yards) apart, and the lower edge of the crossbar must be 2.14 metres (7 feet) above the ground. Each team plays with 11 players on the field during the game including the goalie. Positions you might play include-
Forward: As shown by players A, B, C and D.

  • Midfielders: As shown by players E, F and G.
  • Fullbacks: As shown by players H, I and J.
  • Goalie: As shown by player K
