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.
Using the picture of a hockey field below, answer the questions that follow:
Marking Scheme
1. (b) Least composite number is 4 and the least prime number is 2.
LCM (4, 2) : HCF (4, 2) = 4 : 2 = 2 : 1
a b c
2. (a) For lines to coincide: 1 = 1 = 1
a2 b2 c2
5 7 −3
So, = =
15 21 − k
i.e. k= 9
3. (b) By Pythagoras theorem
The required distance = (200 2
+ 1502 )
= ( 40000 + 22500) = (62500) = 250 m.
So the distance of the girl from the starting point is 250 m.
1 1
4. (d) Area of the Rhombus = × d1 × d2 = 2 × 24 × 32 = 384 cm²
2
Using Pythagoras theorem
2 2
1 1
Side² = d1 + d 2 = 12² +16² = 144 + 256 = 400
2 2
Side = 20 cm
Area of the Rhombus = base × altitude
384 = 20 × altitude
384
So altitude = = 19.2 cm
20
5. (a) Possible outcomes are (HH), (HT), (TH), (TT).
Favorable outcomes (at the most one head) are (HT), (TH), (TT).
3
So probability of getting at the most one head = .
4
6. (d) Ratio of altitudes = Ratio of sides for similar triangles
So, AM : PN = AB : PQ = 2 : 3
7. (b) 2 sin β – cos2 β = 2
2
9. (a) Lines x = a is a line parallel to y axis and y = b is a line parallel to x axis. So they will
intersect.
10. (d) Distance of point A (– 5, 6) from the origin (0, 0) is
( 0 + 5 )2 + ( 0 − 6 )2 = 25 + 36 = 61 units
23
11. (b) a² = 23/25, then a = , which is irrational
5
12. (c) LCM × HCF = Product of two numbers
36 × 2 = 18 × x
x= 4
13. (b) tan A = 3 = tan 60°
So, ∠A = 60°,
Hence, ∠C = 30°.
1 3 3 1
So, cos A cos C – sin A sin C = × – × = 0
2 2 2 2
14. (a) 1x + 1x + 2x = 180°, x = 45°
∠A , ∠B and ∠C are 45°, 45° and 90° respectively
sec A tan A sec 45° tan 45° 2 1
− = − = − =1–1=0
cosec B cot B cosec 45° cot 45° 2 1
total distance 176
15. (d) Number of revolutions = = = 40
circumference 2 × 22 × 0.7
7
perimeter of ∆ABC BC
16. (b) =
perimeter of ∆DEF EF
7.5 2
=
perimeter of ∆DEF 4
So perimeter of ΔDEF = 15 cm
17. (b) Since DE || BC, ΔABC ~ ΔADE (By AA rule of similarity)
AD DE 3 DE
So = i.e. = . So DE = 6 cm
AB BC 7 14
18. (a) Dividing both numerator and denominator by cos β,
4 sin β − 3 cos β 4 tan β − 3 3 − 3
= =
4 sin β + 3 cos β 4 tan β + 3 3 + 3 = 0
19. (d) – 2(– 5x + 7y = 2) gives 10x – 14y = – 4.
a1 b1 c1
Now = = =–2
a2 b2 c2
20. (a) Number of Possible outcomes are 26
Favorable outcomes are M, A, T, H, E, I, C, S
8 4
=
Probability =
26 13
21. (c) Since HCF = 81, two numbers can be taken as 81x and 81y,
ATQ 81x + 81y = 1215
or x + y = 15
which gives four co-prime pairs
1, 14
2, 13
4, 11
7, 8
1
22. (c) Required Area is area of triangle ACD = × 6 × 2 = 6 sq units
2
23. (b) tan α + cot α = 2 gives α = 45°. So tan α = cot α = 1
tan20 α + cot20 α = 120 + 120 = 1 + 1 = 2
24. (a) Adding the two given equations we get: 348x + 348y = 1740.
So, x+y= 5
25. (c) LCM of two prime numbers = product of the numbers
221 = 13 × 17.
So, p = 17 and q = 13
∴ 3p – q = 51 – 13 =38
26. (a) Probability that the card drawn is neither a king nor a queen
52 − 8
=
52
44 11
= =
52 13
27. (b) Outcomes when 5 will come up at least once are
(1, 5), (2, 5), (3, 5), (4, 5), (5, 5), (6, 5), (5, 1), (5, 2), (5, 3), (5, 4) and (5, 6)
11
Probability that 5 will come up at least > 36
28. (c) 1+ sin2 α = 3 sin α cos α
sin2 α + cos2 α + sin2 α = 3 sin α cos α
2 sin2 α – 3 sin α cos α + cos2 α = 0
(2 sin α – cos α) (sin α – cos α) = 0
∴ cot α = 2 or cot α = 1
29. (a) Since ABCD is a parallelogram, diagonals AC and BD bisect each other.
∴ mid point of AC = mid point of BD
x + 1 6 + 2 3 + 4 5 + y
, ,
2 2 = 2 2
∴ ( x − 4 )2 + ( y − 5 )2 = ( x + 2)2 + ( y − 3)2
Solving we get– 12x – 4y + 28 = 0 or 3x + y – 7 = 0

33. (a) The smallest number by which should be multiplied so that its decimal expansion
13
13 1 13 1
terminates after two decimal points is as × = = 0.01
100 13 100 100
35. (a) Since P divides the line segment joining R (– 1, 3) and S (9, 8) in ratio k : 1
9 k − 1 8k + 3
∴ coordinates of P are , .
k + 1 k + 1
9 k − 1 8k + 3
Since P lies on the line x – y + 2 = 0, then k + 1 − k + 1 + 2 = 0
9k – 1 – 8k – 3 + 2k + 2 = 0
2
which gives k =

36. (c)

38. (b) Sum of zeroes = 2 + =−
2 p

i.e.,

Product of zeroes = 2 × 2 = p
r
i.e.

39. (c) 2πr = 100. So, Diameter = 2r = = diagonal of the square.
π
100
side 2 = diagonal of square =

100 50 2
∴ side = =
2π π
40. (b) 3x + y = 243 = 35
So, x+y= 5 ...(1)
243x – y = 3
(35)x – y = 31
So, 5x – 5y = 1 ...(2)
a1 b1
Since, ≠ , so unique solution.
a2 b2
41. (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
42. (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
3
i.e.
t= 2 or t = –
2
Since time cannot be negative, so t = 2 seconds
43. (d) t = – 1 and t = 2 are the two zeroes of the polynomial p(t)
Then, p(t) = k {t – (–1)} (t – 2)
= k(t + 1) (t – 2) = k (t2 – t – 2)
When t = 0 (initially) h1 = 48 ft
p(0) = k (0² – 0 – 2) = 48
i.e. – 2k = 48
So the polynomial is – 24 (t² – t – 2) = – 24t² + 24t + 48
44. (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) = 48 ft
q(0) = k (0² – 1(0) – 6) = 48
i.e. – 6k = 48 or k = – 8
Putting k = – 8 in equation (1), reqd. polynomial is – 8 [t² – 1t + (–6)]
= – 8t² + 8t + 48
45. (a) When the zeroes are negative of each other,
sum of the zeroes = 0
−b
So, = 0
a
− (k − 3)
= 0
−12
k −3
= 0
12
k – 3 = 0,
i.e. k= 3
46. (a) Centroid of ΔEHJ with E (2, 1), H (– 2, 4) and J (– 2, – 2) is
2 + ( − 2) + ( − 2) 1 + 4 + ( − 2 ) 2
, = − , 1
3 3 3
47. (c) If P needs to be at equal distance from A (3, 6) and G (1, – 3), such that A, P and G are
collinear, then P will be the mid-point of AG.
3 + 1 6 + ( − 3) 2, 3
So coordinates of P will be , = 2
2 2
48. (a) Let the point on x-axis equidistant from I (– 1, 1) and E (2, 1) be (x, 0)
Then ( x + 1)2 + (0 − 1)2 = ( x − 2)2 + (0 − 1)2
x2 + 1 + 2x +1 = x2 + 4 – 4x + 1
6x = 3
1
So, x= .
2
1
∴ the required point is ,
0
2
49. (b) Let the coordinates of the position of a player Q such that his distance from K(– 4, 1) is
twice his distance from E(2, 1) be Q(x, y)
Then KQ : QE = 2 : 1
2 × 2 + 1 × − 4 2 × 1 + 1 × 1
Q(x, y) = , = (0, 1)
3 3
50. (d) Let the point on y-axis equidistant from B(4, 3) and C(4, – 1) be (0, y)
