General Instructions:

  1. Answer all the questions under Part – A on a separate answer book.
  2. Write the answers to the questions under Part – B on the question paper itself and attach it to the the answer book of Part A.

Part – A (60 Marks)
Section – I (6 × 2 = 12 Marks)

Note :

  1. Answer ALL the following questions.
  2. Each question carries 2 marks.

Question 1.
Check whether A = {x : x2 = 25 and 6x = 15} is an empty set or not ? Justify your answer.
Solution:
x2 = 25 . ∴ x = \(\sqrt{25}\) = ± 5
6x = 15 ∴ x = \(\frac{15}{6}\) = \(\frac{5}{2}\)
Any value of x is not satisfying the above two equations. So, A is empty set.

Question 2.
Find two numbers whose sum is 27 and product is 182.
Solution:
Let the first number = x
∴ Second number = 27 – x
Product of two numbers = 182
x(27 – x) = 182
27x – x2 = 182
⇒ x2 – 27x + 182 = 0
⇒ x2 – 13x – 14x + 182 = 0
⇒ x(x- 13) – 14(x – 13) = 0
⇒ (x – 13) (x – 14) = 0
⇒ x – 13 = 0 (or) x – 14 = 0
⇒ x = 13 (or) x = 14
∴ If first number =13, then second number = 27 – 13 = 14
If first number =14, then second number = 27 – 14 = 13
∴ Required numbers = 13 and 14.

Question 5.
Find the area of required cloth to cover the heap of grain in conical shape, of whose diameter is 8m and slant height of 3m.
Solution:
Diameter of conical shape (heap of grain) (d) = 8m
Radius (r) = \(\frac{8}{2}\) = 4 m
Slant height l = 3m
L.S.A of the conical shape (heap) = πrl
= \(\frac{22}{7}\) × 4 × 3
= \(\frac{264}{7}\) = 37.71 m2
∴ Area of required cloth to cover the heap of grain = 37.71 m2

Question 6.
ΔABC ~ ΔDEF and their areas are respectively 64 cm2 and 121 cm2.
If EF = 15.4 cm., then find BC.
Solution:
\(\frac{{ar}(\triangle \mathrm{ABC})}{{ar}(\triangle \mathrm{DEF})}\) = \(\left(\frac{B C}{E F}\right)^2\)
\(\frac{64}{121}\) = \(\left(\frac{B C}{15.4}\right)^2\)
= \(\frac{8}{11}\) = \(\frac{B C}{15.4}\)
⇒ BC = \(\frac{8 \times 15.4}{11}\) = 11.2 cm

2x – 3y = 7 …………….. (2)
3x + 2y – 5 = 0
2x – 3y – 7 = 0
a1 = 3, b1 = 2, c1 = -5
a2 = 2, b2 = -3, c2 -7
\(\frac{a_1}{a_2}\) = \(\frac{3}{2}\), \(\frac{b_1}{b_2}\) = \(\frac{2}{-3}\)
\(\frac{a_1}{a_2}\) ≠ \(\frac{b_1}{b_2}\)

2x – 3y – 5 = 0
4x – 6y – 15 = 0
a1 = 2, b1 = -3, c1 = -5
a2 = 4, 2 = -6, c2 = -15
\(\frac{a_1}{a_2}\) = \(\frac{2}{4}\) = \(\frac{2}{4}\),
\(\frac{b_1}{b_2}\) = \(\frac{-3}{-6}\) = \(\frac{1}{2}\)
\(\frac{c_1}{c_2}\) = \(\frac{-5}{-15}\) = \(\frac{1}{3}\)
\(\frac{a_1}{a_2}\) = \(\frac{b_1}{b_2}\) ≠ \(\frac{c_1}{c_2}\)
∴ Given pair of linear equations represent parallel lines.
∴ Given equations are inconsistent.

Question 8.
The 10th term of an AP is 52 and 16th term is 82, then find the 32nd term.
Solution:
Given : An AP where
10th term = 52
16th term = 82
TS 10th Class Maths Model Paper Set 3 with Solutions 4
⇒ -6d = -30
⇒ d = \(\frac{-30}{-6}\) = 5
Substituting d = 5 in the equation (1) we get
a + 9d = 52
a + 9 × 5 = 52
⇒ a + 45 = 52 ⇒ a = 52 – 45 = 7
Now 32nd term = a + 31 d
= 7 + 31 × 5.
= 7 + 155 = 162

Question 9.
Find the zeroes of the quadratic polynomial x2 + 5x + 6 and verify the relationship between the zeroes and coefficients.
Solution:
p(x) = x2 + 5x + 6
If p(x) = 0, then x2 + 5x + 6 = 0
x2 + 2x + 3x + 6 = 0
x(x + 2) + 3(x + 2) = 0
(x + 2) (x + 3) = 0
x + 2 = 0 (or) x + 3 = 0
x = -2 (or) x = -3
∴ Zeroes of p(x) = -2, -3
Let α = -2 and β = -3
Sum of the zeroes α + β = (- 2) + (- 3)

Question 10.
A toy is in the form of a cone mounted on a hemisphere. The diameter of the base and the height of the cone are 6 cm and 4 cm respectively. Find the surface area of the toy. (Take π = 3.14)
Solution:
Diameter of the base of the cone d = 6 cm.
∴ Radius of the base of the cone.
r = \(\frac{d}{2}\) = \(\frac{1}{2}\) = 3 cm.
TS 10th Class Maths Model Paper Set 3 with Solutions 6
Height of the cone = h = 4 cm
Slant height of the cone
l = \(\sqrt{r^2+h^2}\)
= \(\sqrt{(3)^2+(4)^2}\) = \(\sqrt{9+16}\) = \(\sqrt{25}\) = 5 cm
∴ C.S.A. of cone = πrl
= \(\frac{22}{7}\) × 3 × 5 = \(\frac{330}{7}\) cm2
Radius of the hemisphere
\(\frac{d}{2}\) = \(\frac{6}{2}\) = 3 cm.
C.S.A. of the hemisphere = 2πr2
= 2 × \(\frac{22}{7}\) × 3 × 3 = \(\frac{396}{7}\)
Hence the surface area of the toy = C.S.A. of cone + C.S.A. of hemisphere
= \(\frac{330}{7}\) +\(\frac{396}{7}\)
= \(\frac{726}{7}\) = 103.71 cm2

∴ The total number of outcomes n(S) = 52

i) Let E be the event ‘The card is a king of red colour”. ,
The no.of favourable outcomes n(E) = 2
∴ P(E) = \(\frac{\mathrm{n}(\mathrm{E})}{\mathrm{n}(\mathrm{S})}\) = \(\frac{2}{52}\) = \(\frac{1}{26}\)

ii) Let F be a event “The card is a face card”.
n(F) = 12
∴ P(E) = \(\frac{\mathrm{n}(\mathrm{F})}{\mathrm{n}(\mathrm{S})}\) = \(\frac{12}{52}\) = \(\frac{3}{13}\)

iii) Let G be a event The card is.a red face card”.
n(G) = 6
P(G) = \(\frac{\mathrm{n}(\mathrm{G})}{\mathrm{n}(\mathrm{S})}\) = \(\frac{6}{52}\) = \(\frac{3}{26}\)

iv) Let H be a event “The card is the jack of hearts”.
n(H) = 1
P(H) = \(\frac{\mathrm{n}(\mathrm{H})}{\mathrm{n}(\mathrm{S})}\) = \(\frac{1}{52}\)

Question 15.
A) The sum of the third and seventh terms of an AP is 6 and their product is 8. Find the sum of first sixteen terms of the AP.
Solution:
In an AP
3rd term = a3 = a + 2d
7th term = a7 = a + 6d
From given a3 + a7 = 6 and a3 + a7 = 8
Now take a3 + a7 = 6
a + 2d + a + 6d = 6
2a + 8d = 6
a + 4d = 3
a = 3 – 4d …………… (1)
Now take a3 × a7 = 8
(a + 2d) (a + 6d) = 8 …………… (2)
Substitute a = 3 – 4d in eqn. (2)
(3 – 4d + 2d) (3 – 4d + 6d) = 8
(3 – 2d) (3 + 2d) = 8
(3)2 – (2d)2 = 8
9 – 4d2 = 8
9 – 8 = 4d2
4d2 = 1 => d2 = \(\frac{1}{4}\)
d = \(\frac{1}{2}\)
From (I) a = 3 – 4d
= 3 – 4 × \(\frac{1}{2}\) = 3 – 2 = 1
a = 1
Sum of 16 terms
= Sn = \(\frac{n}{2}\)[2a + (n – 1)d]

B) If the median of 60 observations, given below is 28.5 find the values of x and y.
TS 10th Class Maths Model Paper Set 3 with Solutions 13
Solution:

Class Interval Frequency c.f
0 – 10 5 5
10 – 20 x 5 + x
20 – 30 20 25 + x
30 – 40 15 40 + x
40 – 50 y 40 + x + y
50 – 60 5 45 + x + y

Median = l + (\(\frac{\left(\frac{n}{2}-c . f\right)}{f}\)) × h
It is given that Σf = n = 60
So, 45 + x + y = 60
x + y = 60 – 45 = 15
x + y= 15 ………….. (1)
The median is 28.5 which lies between 20 and 30.
∴ Median class = 20 – 30
Lower boundary of the median class ‘l’ = 20
\(\frac{N}{2}\) = \(\frac{60}{2}\) = 30
cf – cumulative frequency = 5 + x
h = 10
Median =l + (\(\frac{\left(\frac{n}{2}-c . f\right)}{f}\)) × h
⇒ 28.5 = 20 + \(\frac{30-5-x}{20}\) × 10
28.5 = 20 + \(\frac{25-x}{2}\)
\(\frac{25-x}{2}\) = 28.5 – 20 = 8.5
25 – x = 2 × 8.5
x = 25 – 17 = 8
also from (1); x + y = 15 8 + y = 15 ⇒ y = 7
∴ x = 8; y = 7.

A) From a pack of 52 playing cards, Jacks, Queens, Kings and Aces of red colour are removed. From the remaining, a card is drawn at random. Find the probability that the card drawn is (i) a black queen, (ii) a red card.
Solution:
Probability of black queen = \(\frac{1}{26}\)
Probability of red card = \(\frac{1}{2}\)
n(S) = 52
Probability of black queen n(a) = 2
p(a) = \(\frac{\mathrm{n}(\mathrm{a})}{\mathrm{n}(\mathrm{S})}\) = \(\frac{2}{52}\) = \(\frac{1}{26}\)
Probability of a red card n(b) = 26
p(b) = \(\frac{\mathrm{n}(\mathrm{b})}{\mathrm{n}(\mathrm{S})}\) = \(\frac{26}{52}\) = \(\frac{1}{2}\)

B) If A = (x : x is a prime less than 20} and B = {x : x is a whole number less than 10},
then verify n(A∪B) = n(A) + n(B) – n(A∩B).
Solution:
Given
A = {x : x is a prime less than 20}
A = {2,3, .5, 7, 11,13, 17,19} n(A) = 8
B = {x: x is a whole number less than 10} = {0,1,2, 3,4, 5, 6, 7, 8, 9} n(B) = 10
n(A∪B) = n(A) + n(B) – n(A∩B) ………. (1)
A∩B = {2, 3, 5, 7, 11, 13, 17, 19} ∩ {0, 1,2, 3,4, 5, 6, 7, 8, 9}
= {2, 3, 5, 7}
n(A∩B) = 4
From (1) n (A∪B) = 8 + 10 – 4 = 14.

Question 17.
A) Draw the graph of p(x) = x2 – 6x + 9 and find zeroes. Verify the zeroes of the polynomial.
Solution:
Given p(x) = x2 – 6x + 9
Let y = x2 – 6x + 9
TS 10th Class Maths Model Paper Set 3 with Solutions 14
We observe that the graph touches the X – axis at (3, 0).
So, the zeroes of the given polynomial are equal.
∴ The zeroes of p(x) are 3, 3.
Justification:
Given p(x) = x2 – 6x + 9 = 0
⇒ x2 – 3x – 3x + 9 = 0
⇒ x(x – 3) – 3(x – 3) = 0
⇒ (x- 3) (x – 3) = 0
x – 3 = 0 (or) x – 3 – 0
x = 3 (or) x = 3
∴ Zeroes of p(x) = 3,3
