**SECTION – A**

**1. If a point P is 13 cm away from the centre O of a circle and the length PT of the tangent drawn from P to the circle is 12 cm. Then find the radius of the circle.Answer :** 1. If a point P is 13 cm away from the centre O of a circle and the length PT of the tangent drawn from P to the circle is 12 cm. Then find the radius of the circle.

In ΔPTO, OP

^{2}= PT

^{2}+ OT

^{2}

⇒ 13

^{2}= 12

^{2}+ OT

^{2}⇒ 169 – 144 = OT

^{2}⇒ 25 = OT

^{2}⇒ OT = 5 cm

**2. For what value of k will k + 11, 2k – 1 and 2k + 7 are the consecutive terms of an A.P.?Answer : **Let k + 11, 2k – 1 and 2k + 7 are in A.P.

∴ (2k – 1) – (k + 11) = (2k + 7) – (2k – 1)

⇒ 2k – 1 – k – 11 = 2k + 7 – 2k + 1

⇒ k – 12 = 8 ⇒ k = 20

**3. Find the roots of the quadratic equation a ^{2}b^{2}x^{2} + b^{2}x – a^{2}x – 1 = 0.** The given quadratic equation is a

Answer :

^{2}b

^{2}x

^{2}+ b

^{2}x – a

^{2}x – 1 = 0

⇒ b

^{2}x (a

^{2}x + 1) – 1 (a

^{2}x + 1) = 0

⇒ (a

^{2}x + 1)(b

^{2}x – 1) = 0 ⇒ a

^{2}x + 1 = 0 or b

^{2}x – 1 = 0

⇒ x = −1 / a

^{2}or x = 1 / b

^{2}

**OR**

**Find the value of k, for which the quadratic equation x ^{2} – kx + 4 = 0 has equal roots.Answer : **The given equation is, x

^{2}– kx + 4 = 0

For equal roots, D = b

^{2}– 4ac = 0

⇒ (–k)

^{2}– 4(1)(4) = 0 ⇒ k

^{2}= 16 ⇒ k = ± 4

**4. Find two consecutive positive integers, the sum of whose squares is 61.Answer :** Let the two consecutive positive integers be x and x + 1.

According to question, x2 + (x + 1)

^{2}= 61

⇒ x

^{2}+ x

^{2}+ 2x + 1 = 61

⇒ 2x

^{2}+ 2x = 60 ⇒ x

^{2}+ x – 30 = 0

⇒ x

^{2}+ 6x – 5x – 30 = 0 ⇒ x(x + 6) – 5(x + 6) = 0 ⇒ (x + 6)(x – 5) = 0

⇒ x = -6 or x = 5 ⇒ x = 5 [Since x is a positive integer]

And x + 1 = 6

∴ The two consecutive positive integers are 5 and 6.

**5. The mode of the following frequency distribution is 38. Find the value of x. Answer :**

**6. A cone and a hemisphere have equal bases and equal volumes. Find the sum of the numerator and denominator of ratio of height of cone and radius of hemisphere.Answer :** Let r be the radius of both the cone and hemisphere and h be the height of the cone.

∴ Volume of cone = Volume of hemisphere

∴ Required sum = 2 + 1 = 3

**OR**

**Three cubes each of edge 3 cm are joined end to end. Find the surface area of the resulting cuboid.****Answer :** Length of the resulting cuboid = 3 + 3 + 3 = 9 cm

Breadth of the resulting cuboid = 3 cm

Height of the resulting cuboid = 3 cm

∴ Surface area of the resulting cuboid = 2(lb + bh + hl)

= 2(9 × 3 + 3 × 3 + 3 × 9) = 2 × 63 = 126 cm^{2}

**SECTION – B**

**7. Calculate the mean and median for the following frequency distribution: Answer : **

**Answer : **

**8. Draw a circle of radius 5 cm. From a point P, 8 cm away from its centre, construct a pair of tangents to the circle. Measure the length of each one of the tangents.****Answer : **Steps of construction :

Step-I : Draw a circle with O as centre and radius 5 cm.

Step-II : Mark a point P outside the circle such that OP = 8 cm.

Step-III : Join OP and draw its perpendicular bisector, which cuts OP at M.

Step-IV : Draw a circle with M as centre and radius equal to MP to intersect the given circle at the point T and T′. Join PT and PT′.

Hence, PT and PT′ are the required tangents.

**9. A person walking 20 m towards a chimney in a horizontal line through its base observes that its angle of elevation changes from 30° to 45°. Find the height of chimney.Answer :** Suppose height of the chimney is h metres. Let A and B be the point of observation and BC be x m.

**OR**

**Answer** : Let AB be the lighthouse of height 150 m.

Let initially boat is at C and after 2 minutes it reaches at D.

**10. If the median of the distribution given below is 28.5, then find the values of x and y.**

**SECTION – C**

**11. The sums of n, 2n, 3n terms of an A.P. are S1, S2, S3 respectively. Prove that S3 = 3(S2 – S1).Answer : **Let a be the first term and d be the common difference of the A.P.

**12. Prove that opposite sides of a quadrilateral circumscribing a circle subtend supplementary anglesat the centre of the circle.Answer :** Let ABCD be the quadrilateral circumscribing a circle at the center O such that it touches the circle at the point P,Q,R,S. Let join the vertices of the quadrilateral ABCD to the center of the circle

In ΔOAP and ΔOAS

AP=AS ( Tangents from to same point A)

PO=OS ( Radii of the same circle)

OA=OA ( Common side)

so, ΔOAP=ΔOAS (SSS congruence criterion)

∴ ∠POA=∠AOS (CPCT)

⇒ ∠1=∠8

Similarly, ∠2=∠3, ∠4=∠5 and ∠6=∠7

∠1+∠2 +∠3+∠4+∠5+∠6+∠7+∠8 = 360⁰

⇒ (∠1 +∠8) +(∠2 +∠3) + (∠4 +∠5) + (∠6 +∠7) = 360⁰

⇒ 2(∠1) + 2(∠2) + 2(∠5) + 2(∠6) = 360⁰

⇒ (∠1) + (∠2) + (∠5) + (∠6) = 180⁰

∴ ∠AOD + ∠COD=180⁰

Similarly, ∠BOC + ∠DOA = 180⁰

A circle is inscribed in a DABC having sides 16 cm, 20 cm and 24 cm as shown in figure. Find AD, BE and CF.

**Answer : **Since, tangents drawn from an external point to a circle are equal.

∴ AD = AF = x, BD = BE = y and CE = CF = z

According to the question,

AB = x + y = 24 cm …(i)

BC = y + z = 16 cm …(ii)

AC = x + z = 20 cm …(iii)

Subtracting (iii) from (i), we get

y – z = 4 …(iv)

Adding (ii) and (iv), we get

2y = 20 ⇒ y = 10 cm

Substituting the value of y in (i) and (ii), we get

x = 14 cm, z = 6 cm

∴ AD = 14 cm, BE = 10 cm and CF = 6 cm.

**CASE STUDY QUESTION – 2**

**14. A boy 4 m tall spots a pigeon sitting on the top of a pole of height 54 m from the ground. The angle of elevation of the pigeon from the eyes of boy at any instant is 60°. The pigeon flies away horizontally in such a way that it remained at a constant height from the ground. After 8 seconds, the angle of elevation of the pigeon from the same point is 45°.**

Based on the above information, answer the following questions. (Take √3 =1.73 )

(i) Find the distance of first position of the pigeon from the eyes of the boy.

(ii) How much distance the pigeon covers in 8 seconds?**Answer** : (i) Distance of first position of pigeon from the eyes of boy = AC
