Solution of Sample Paper

Section – A

1. Given, 6x² – x – 2 = 0

⇒ 6x² + 3x – 4x – 2 = 0           ½

⇒ 3x(2x + 1) -2(2x + 1) = 0            ½

⇒ (2x + 1)(3x – 2) = 0           ½

Either 3x – 2 = 0 or 2x + 1 = 0

x = 2/3 or x = – 1/2

Roots of equation are 2/3 and – 1/2.          ½

2. Given, a4 = 0

⇒ a + 3d = 0

⇒ a = -3d …..(i)         ½

25th term, a25 = a + 24d

= -3d + 24d [from (i)]

a25 = 21d ……..(ii)            ½

11th term, a11= a + 10d

= -3d + 10d [from (i)]

i.e., a11 = 7d ……(iii)          ½

From (ii) and (iii),

a25= 3(a11) Hence proved.          ½

OR

The formula to find any term from end

= l – (n – 1)d          ½

Here, l = 136, n = 13 and d = 10 – 3 = 7            ½

13th term from last = 136 – (13 – 1)7

= 136 – 84

=52          1

6. Given, ∠BAC = 34°

∠ACB = 90°

DiagramDescription automatically generated         (Angle in a semi-circle is 90°)         ½

In △ABC,

∠BAC + ∠ACB + ∠ABC = 180° (Angle sum property of a A)          ½

⇒ 34° + 90° + ∠ABC = 180°

⇒ 124° + ∠ABC = 180°

⇒ ∠ABC = 180° – 124°

⇒ ∠ABC = 56°.         1

Let AB and CD be the multi-storied building and the building respectively.

Let the height of the multi-storied building = h m and the distance between the two buildings = x m.

AE = CD = 8m [Given]

BE = AB – AE = (h – 8) m

and AC = DE = x m [Given]

Also, ∠FBD = ∠BDE = 30° (Alternate angles)

and ∠FBC = ∠BCA = 45° (Alternate angles)          1

Now, In △CAB, ∠A = 90°

⇒ tan 45° = AB/AC

⇒ l = x/h

⇒ x = h …..(i)

In △DEB, ∠E = 90°

Hence, height multi-storied building is (12 + 4√3) m           ½

OR

8. Given, A.P. = 7, 11, 15, 19, …….

First term (a) = 7 and common difference (d) = 4         ½

For nth term, Tn = a + (n – 1)d

T16 = 7 + (16 – 1)4

= 67         1

According to the property that length of tangents drawn from same external point are equal in length.

Let BP = MB = a,

PC = CQ = b

and AQ = AM = c

From figure, it is clear that,

b + c = 12

a + b = 5

a + c = 13 ……(i)           1

Add all above equations,

2(a + b + c) = 30

a + b + c = 15 …(ii)

From (i) & (ii), we get

b = 2 cm

Hence, radius of the circle is 2 cm.         1

10. Let the three consecutive natural numbers be x, x + 1 and x + 2, then according to question.           ½

(x + 1)² = (x + 2)² – x² + 77          1

⇒ x² + 2x + 1 = x² + 4x + 4 = x² + 77

⇒ x² – 2x – 80 = 0            ½

⇒ x² – 10x + 8x – 80 = 0

⇒ x(x – 10) + 8(x – 10) = 0

⇒ (x – 10) (x + 8) = 0

Thus x = 10

or x = -8

Rejecting -8, we get

x = 10

Hence, three numbers are 10, 11 and 12.           1

13. (i) Highest frequency class = 115-130 So, it is a modal class.

∴ Lower limit of modal class = 115         ½

Again, n/2 = 45/2 = 22.5,

which lies in class interval 100-115.

So, it is a median class.

∴ Upper limit of median class = 115        ½

Hence, sum = 115 + 115

= 230.        1

(ii) Here, modal class = 115-130

f₁ =15, f₂ = 7, f0 = 12, l = 115 and h = 15
