Answers:
Directions (1 – 5):
1) Answer: b)
Let, number of dancers in group A = n
Doctors = 6
Singers = 3
Engineers = 5
Total number of persons in the group = 6 + 3 + n + 5 = 14 + n
According to the question
6c1 x 3c1 x nc1 x 5c1 x (14 + n – 4)c1 = 5040
=> 6 x 3 x n x 5 x (10 + n)c1 = 5040
=> n x (10 + n) = 5040/90
=> n2 + 10n = 56
=> n2 + 10n – 56 = 0
=> n2 + 14n – 4n – 56 = 0
=> n(n + 14) – 4(n + 14) = 0
=> (n – 4)(n + 14) = 0
=> n = 4, -14 (not valid)
=> n = 4
Hence, Dancers = 4
Total number of persons in the group = 14 + 4 = 18
Required probability = (6c2 x 4c2)/18c4
= (15 x 6)/3060
= 1/34
2) Answer: a)
Let, number of doctors in group E = m
And number of engineers in group E = n
Singers = 8
Dancers = 10
Total number of persons in group E = m + n + 8 + 10 = 18 + m + n
According to the question
m/(18 + m + n) = 3/8
=> 8m = 54 + 3m + 3n
=> 8m – 3m – 3n = 54
=> 5m – 3n = 54 —————– (i)
And
8/(18 + m + n) = ¼
=> 32 = 18 + m + n
=> m + n = 32 – 18
=> m + n = 14 ————- (ii)
Equation (i) + 3 x Equation (ii)
5m – 3n + 3m + 3n = 54 + 42
=> 8m = 96
=> m = 12
From (ii)
12 + n = 14
=> n = 14 – 12
=> n = 2
Hence, Doctors = 12
Engineers = 2
Required number of ways = 12c2 x 8c1 x 10c1
= 66 x 8 x 10
= 5280
3) Answer: d)
Let, number of singers in group C = n
Doctors = 8
Dancers = 6
Engineers = 2
Total number of persons in group C = n + 8 + 6 + 2 = 16 + n
According to the question
8c2 x nc1 x 6c2 x 2c1 = 2520
=> 28 x n x 15 x 2 = 2520
=> n = 2520/840
=> n = 3
Singer = 3
Total number of persons in group C = 16 + 3 = 19
Probability of selecting 2 singers from group C = 3c2/19c2
= 3/171
= 1/57
Probability of selecting 2 singers from group F = 7c2/24c2
= 21/276
= 7/92
Required ratio = 1/57: 7/92 = 92:399
4) Answer: a)
Let, number of doctors in group B = m
And number of dancers in group B = n
Singers = 2
Engineers = 7
Total number of persons in group B = m + n + 2 + 7 = 9 + m + n
m/(9 + m + n) = 2/9
=> 9m = 18 + 2m + 2n
=> 9m – 2m – 2n = 18
=> 7m – 2n = 18 ————— (i)
And
2/(9 + m + n) = 1/9
=> 18 = 9 + m + n
=> m + n = 18 – 9
=> m + n = 9 —————- (ii)
Equation (i) + 2 x Equation (ii)
7m – 2n + 2m + 2n = 18 + 18
=> 9m = 36
=> m = 4
From (ii)
4 + n = 9
=> n = 9 – 4
=> n = 5
Doctors = 4
Dancers = 5
Total number of persons in group B = 9 + 4 + 5 = 18
Quantity I:
Required number of ways = 4c2 x 2c1 x 5c1 x 7c1
= 6 x 2 x 5 x 7
= 420
Quantity II:
Required number of ways =4c1 x 2c2 x 5c2
= 4 x 1 x 10
= 40
Hence, Quantity I > Quantity II
5) Answer: c)
Let, number of engineers in group D = n
Doctors = 3
Singers = 6
Dancers = 4
Total number of persons in group D = n + 3 + 6 + 4 = 13 + n
From I:
3/(13 + n) = 1/6
=>18 = 13 + n
=> n = 18 – 13
=> n = 5
Required ratio = (3 + 6 + 4 + 5): (5 + 7 + 9 + 3)
= 18: 24
= 3:4
From II:
3c1 x 6c1 x 4c1 x nc1 = 360
=> 3 x 6 x 4 x n = 360
=> n = 360/72
=> n = 5
Required ratio = (3 + 6 + 4 + 5): (5 + 7 + 9 + 3)
= 18: 24
= 3:4
Hence, either statement I alone or statement II alone is sufficient to answer the question.
Directions (6 – 10):
6) Answer: d)
Area of field A = 15400/25 = 616 m2
We know that
Area of a rectangle = length x breadth
=> 616 = 28 x breadth
=> Breadth = 616/28
=> Breadth = 22 m
We know that
Perimeter of rectangle = 2 x (length + breadth)
= 2 x (28 + 22)
= 2 x 50
= 100 m
Cost of fencing of field A = 100 x 10 = Rs.1000
Area of field D = 5760/30 = 192 m2
We know that
Area of a triangle = ½ x base x height
=> 192 = ½ x 16 x height
=> Height = 192 x 2/16
=> Height = 24 m
But sides of the triangle are not known, hence, cost of fencing cannot be find out and required ratio cannot be find out.
7) Answer: b)
We know that
Area of a circle = πr2
=> Area of field B = 22/7 x 21 x 21 = 1386 m2
Cost of flooring/m2 of field B = 34650/1386 = Rs.25
We know that
Area of trapezium = ½ x (sum of the bases) x height
=> Area of field E = ½ x (18 + 24) x 30
= ½ x 42 x 30
= 630 m2
Cost of flooring/m2 of field E = 12600/630 = Rs.20
Required percentage = 25/20 x 100 = 125%
8) Answer: d)
Area of field F = 15000/25 = Rs.600
We know that
Area of parallelogram = base x height
=> 600 = base x 20
=> Base = 600/20
=> Base = 30 m
Perimeter of field F = 2 x (30 + 24)
= 2 x 54
= 108 m
Cost of fencing of field F = 108 x 10 = Rs.1080
We know that
Perimeter of a square = 4 x side
= 4 x 24
= 96 m
Cost of fencing of field C = 96 x 12 = Rs.1152
Required average = (1080 + 1152)/2
= 2232/2
= Rs.1116
e) Quantity I = Quantity II or no relation can be established.
9) Answer: b)
Quantity I:
Perimeter of field A = 920/10 = 92 m
We know that
Perimeter of a rectangle = 2 x (length + breadth)
=> 92 = 2 x (28 + breadth)
=> 28 + breadth = 92/2
=> Breadth = 46 – 28
=> Breadth = 18 m
We know that
Area of rectangle = length x breadth
= 28 x 18
= 504 m2
Total cost of flooring of field A = 504 x 25 = Rs.12600
Quantity II:
Radius of field G = 21 + 7 = 28 m
We know that
Area of circle = πr2
=> Area of field G = 22/7 x 28 x 28 = 2464 m2
Total cost of flooring of field G = 2464 x 8 = Rs.19712
Hence, Quantity I < Quantity II
10) Answer: d)
From I:
Field H is rectangular in shape. Total cost of fencing of field H is Rs.960.
From II:
Length of field H is 4 m more than its breadth. Cost of flooring/m2 of field H is Rs.22.
From I and II:
Let, breadth of field H = b m
=> Length = (b + 4) m
Perimeter of field H = 960/15 = 64 m
We know that
Perimeter of a rectangle = 2 x (length + breadth)
=> 64 = 2 x (b + 4 + b)
=> 2b + 4 = 64/2
=> 2b = 32 – 4
=> b = 28/2
=> b = 14
Hence, breadth = 14 m
Length = 14 + 4 = 18 m
We know that
Area of rectangle = length x breadth
=> Area of field H = 18 x 14 = 252 m2
Total cost of flooring of field H = 252 x 22 = Rs.5544
Hence, both statements I and II together are needed to answer the question.
