### QUESTION PAPER CODE 16E(A)

**SECTION – I**

** (4 * 1 = 4)**

**Question 1: In â–³ABC, LM || BC and [AL / LB] = [2 / 3], AM = 5cm, find AC.**

**Solution: **

AL / LB = AM / MC

2 / 3 = 5 / MC

MC = 15 / 2

= 7.5 cm

AC = AM + MC

= 5 + 7.5

= 12.5 cm

**Question 2: Evaluate sin 15 ^{o} * sec 75^{o}.**

**Solution:**

sin 15^{o} * sec 75^{o}

= sin 15^{o} * sec (90^{o} – 15^{o})

= sin 15^{o} * cosec 15^{o}

= sin 15^{o} * (1 / sin 15^{o})

= 1

**Question 3: A box contains 3 blue and 4 red balls. What is the probability that the ball taken out randomly will be red?**

**Solution:**

Total number of balls = 3 + 4 + 7 = 14

Total number of possible outcomes = 7

Favourable outcomes that the ball will be a red ball = 4

Probability for the ball drawn to be red = 4 / 7

**Question 4: The mean of a grouped data is calculated by. What do the terms â€˜fâ€™ and â€˜dâ€™ represent in the above formula?**

Solution:

f = frequency of the class

d = deviation = x_{i} – a

**SECTION – II**

** (5 * 2 = 10)**

**Question 5: If the distance between 2 points (x, 1) and (-1, 5) is 5. Find the value of x.**

**Solution: **

Distance between 2 points = âˆš(x_{1} – x_{2})^{2} + (y_{1} – y_{2})^{2}

Distance between (x, 1) and (-1, 5) = 5

âˆš(x – [-1])^{2} + (1 – 5)^{2} = 5

âˆš(x + 1)^{2} + (-4)^{2} = 5

x^{2} + 1 + 2x + 16 = 25

x^{2} + 2x – 8 = 0

(x + 4) (x – 2) = 0

x = -4, 2

**Question 6: Find the length of the tangent from a point 13cm away from the centre of the circle of radius 5cm.**

**Solution:**

The radius of the circle = 5cm

Distance between the centre and the external point (d) = 13cm

Length of the tangent = âˆšd^{2} – r^{2}

= âˆš13^{2} – 5^{2}

= âˆš169 – 25

= âˆš144

= 12 cm

**Question 7: If cos A = 7 / 25, then find sin A and cosec A. What do you observe?**

**Solution:**

In right-angled triangle ABC,

cos A = 7 / 25 [AB / CA]

x^{2} + 7^{2} = 25^{2}

x^{2} = 25^{2} – 7^{2}

x^{2} = 625 – 49

x^{2} = 576

x = 24

sin A = 24 / 25

cosec A = 25 / 24

It is observed that sin A = 1 / cosec A

**Question 8: Rehman observed the top of a temple at an angle of elevation of 30 ^{o} when the observation point is 24m away from the foot of the temple. Find the height of the temple.**

**Solution:**

Distance between the observer and the foot of the tower = 24m

Height of the temple tower = â€˜hâ€™ m

Î˜ = 30^{o}

From triangle ABC,

tan 30^{o} = BC / AB

1 / âˆš3 = h / 24

âˆš3h = 24

h = 24 / âˆš3

h = 8âˆš3 m

Height of the tower = 8âˆš3 m

**Question 9: Write the mid values of the following frequency distribution.**

CI |
8 – 11 | 12 – 15 | 16 – 19 | 20 – 23 | 24 – 27 | 28 – 31 | 32 – 35 |

f |
4 | 4 | 5 | 13 | 20 | 14 | 8 |

**Solution:**

CI |
8 – 11 | 12 – 15 | 16 – 19 | 20 – 23 | 24 – 27 | 28 – 31 | 32 – 35 |

f |
4 | 4 | 5 | 13 | 20 | 14 | 8 |

Mid values |
9.5 | 13.5 | 17.5 | 21.5 | 25.5 | 29.5 | 33.5 |

**Question 10: **

**[a] Prove that (sin A + cosec A) ^{2} + (cos A + sec A)^{2} = 7 + tan^{2} A + cot^{2} A**

**OR**

**[b] ABC is a right angled triangle, which is right angled at C. Let BC = a, CA = b, AB = c and let p be the length of the perpendicular form C on AB. **

**Prove that: **

**[i] pc = ab**

**[ii] 1 / p ^{2} = 1 / a^{2} + 1 / b^{2}**

**Solution:**

^{2}+ (cos A + sec A)

^{2}= 7 + tan

^{2}A + cot

^{2}A

Consider LHS = (sin A + cosec A)^{2} + (cos A + sec A)^{2}

= sin^{2} A + cosec^{2} A + 2 sin A cosec A + cos^{2} A + sec^{2} A + 2 cos A sec A

= (sin^{2} A + cos^{2} A) + 2 (1) + cosec^{2} A + 2 (1) + sec^{2} A

= 1 + 2 + 1 + cot^{2} A + 2 + 1 + tan^{2} A

= 7 + cot^{2} A + tan^{2} A

Area of â–³ABC = (1 / 2) * AB * CD

= (1 / 2) * cp —- (1)

Area of â–³ABC = (1 / 2) * BC * AC

= (1 / 2) * ab —- (2)

From the equations (1) and (2),

(1 / 2) * cp = (1 / 2) * ab

cp = ab

c = ab / p

In â–³ABC the right angle is at C.

AB^{2} = BC^{2} + AC^{2}

c^{2} = a^{2} + b^{2}

(ab / p)^{2} = a^{2} + b^{2}

a^{2} b^{2} / p^{2} = a^{2} + b^{2}

1 / p^{2} = a^{2} + b^{2} / a^{2} b^{2}

1 / p^{2} = a^{2} / a^{2} b^{2} + b^{2} / a^{2} b^{2}

1 / p^{2} = 1 / b^{2} + 1 / a^{2}

**Question 11: Find the median of the following data.**

**[a]**

CI |
11 – 15 |
16 – 20 |
21 – 25 |
26 – 30 |
31 – 35 |
36 – 40 |

f |
3 |
5 |
9 |
12 |
7 |
4 |

** OR**

**[b] In what ratio does the point (-4, 6) divide the line segment joining the points A (-6, 10) and B (3, -8)?**

**Solution:**

CI |
11 – 15 | 16 – 20 | 21 – 25 | 26 – 30 | 31 – 35 | 36 – 40 |

f |
3 | 5 | 9 | 12 | 7 | 4 |

Cf |
3 | 8 | 17 | 29 | 36 | 40 |

n = 40

(n / 2) = 40 / 2 = 20

l = 25.5

f = 12

cf = 17

h = 5

Median = l + {[(n / 2) – cf] / [f]} * h

= 25.5 + {[20 – 17] / 12} * 5

= 26.75

[b] Let (-4, 6) divide the line segment joining the points A (-6, 10) and B (3, -8) in the ratio m_{1}:m

_{2}

(x, y) = (m_{1}x_{2} + m_{2}x_{1}) / (m_{1} + m_{2}) , (m_{1}y_{2} + m_{2}y_{1}) / (m_{1} + m_{2})

(-4, 6) = (3m_{1} – 6m_{2}) / (m_{1} + m_{2}) , (-8m_{1} + 10m_{2}) / (m_{1} + m_{2})

-4 = 3m1 – 6m2 / (m_{1} + m_{2}) and 6 = (-8m1 + 10m2) / (m_{1} + m_{2})

-4 = 3m1 – 6m2 / (m_{1} + m_{2})

-4m_{1} – 4m_{2} = 3m_{1} – 6m_{2}

-4m_{1} – 3m_{1} = -6m_{2} + 4m_{2}

-7m_{1} = -2m_{2}

m_{1} / m_{2} = 2 / 7

m_{1} : m_{2} = 2 : 7

The point (-4, 6) divides the line segment joining the points A (-6, 10) and B (3, -8) in the ratio 2:7.

**Question 12: **

**[a] Two dice are thrown at the same time. What is the probability that the sum of two numbers appearing on the top of the dice is **

**[i] 10**

**[ii] less than or equal to 12**

**[iii] a prime number**

**[iv] multiple of 3**

** OR**

**[b] A tree breaks due to a storm and the broken part bends so much that the top of the tree touches the ground by making 30 ^{o} angle with the ground. The distance between the foot of the tree and the top of the tree on the ground is 6m. Find the height of the tree before falling down.**

**Solution:**

(1, 1)(1, 2)(1, 3)(1, 4)(1, 5)(1, 6)

(2, 1)(2, 2)(2, 3)(2, 4)(2, 5)(2, 6)

(3, 1)(3, 2)(3, 3)(3, 4)(3, 5)(3, 6)

(4, 1)(4, 2)(4, 3)(4, 4)(4, 5)(4, 6)

(5, 1)(5, 2)(5, 3)(5, 4)(5, 5)(5, 6)

(6, 1)(6, 2)(6, 3)(6, 4)(6, 5)(6, 6)

Total possible outcomes = 6 * 6 = 36

[i] Favourable outcomes for the sum to be 10 = (4, 6), (5, 5) and (6, 4)Number of favourable outcomes for the sum to be 10 = 3

P(E) = Number of favourable outcomes / Total number of outcomes

= 3 / 36

= 1 / 12

[ii] Number of favourable outcomes for the sum to be less than or equal to 12 = 36P(sum â‰¦ 12) = 36 / 36 = 1

[iii] Favourable outcomes for the sum to be a prime number = (1, 1), (1, 2), (1, 4), (1, 6), (2, 1), (2, 3), (2, 5), (3, 2), (3, 4), (4, 1), (4, 3), (5, 2), (5, 6), (6, 1), (6, 5)Number of favourable outcomes for the sum to be a prime number = 15

P(E) = 15 / 36

= 5 / 12

[iv] Favourable outcomes for the sum to be a multiple of 3 = (1, 2), (1, 5), (2, 1), (2, 4), (3, 3), (3, 6), (4, 2), (4, 5), (5, 1), (5, 4), (6, 3), (6, 6)Number of favourable outcomes for the sum to be a multiple of 3 = 12 / 36 = 1 / 3

[b]Let the height of the tree before the fall be AB = (x + y) m

BD = 6cm

The tree is broken at C.

Its top A touches the ground at D.

AC = CD = y m

The angle of elevation = âˆ BDC = 30^{o}

BC = x m

In the right-angled triangle CBD,

tan 30^{o} = BC / BD

1 / âˆš3 = x / 6

âˆš3x = 6

x = 6 / âˆš3 = 2âˆš3 m

cos 30^{o} = BD / CD

âˆš3 / 2 = 6 / y

âˆš3y = 12

y = 12 / âˆš3

= 4âˆš3 m

Height of the tree before falling = 2âˆš3 + 4âˆš3 = 6âˆš3 m

**Question 13: **

**[a] Construct a triangle PQR, where QR = 5.5cm, âˆ Q = 65 ^{o} and PQ = 6cm. Then draw another triangle whose sides are 2 / 3 times of the corresponding sides of triangle POR.**
