Solutions:
1. D) Series is 23 - 1, 43 -3, 63 - 5, 83 - 7 …….
2. E) Series is × 1+7, ×2 - 6, ×3 + 5, ×4 - 4 ………
3. E) Series is × 2+1, ×2+ 0, ×2 - 1, ×2 - 2, ×2 - 3 ………
4. D) Series is ×12 + 1, ×22 + 3, ×32 + 5, ×4+ 7…….
5. C) Series is –112 + 4, –102 + 8, –92 + 12, –82 + 16
8. E) From Statement I:
Let the length of the train be x metre.
Therefore Length of platform 3x = 3x/2 meter
From Statement II:
Speed of train = [(3x/2 + x)/25] = 5x/50 = x/10 …… (i)
But x is not known. Hence, we proceed.
From Statement III:
Speed of train = x/19 ….. (ii)
Clearly we reach at no unique conclusion.
9. D) From statement I,
80% children speak languages other than Hindi.
From statement II,
=> Total number of children = [(44 × 100)/80] = 55
10. E) From statements I and II,
Volume of tank = AB cubic metres
From statements II and III,
Radius of base = B/2
Therefore, Volume = П × (Radius)^2 × Height
From statements I and III,
Area of base = A sq. metres.
Hence, radius can be determined.
Height = 2 × radius.
Clearly, after knowing height and area of base, volume can be determined.
11. B) Let the no of laptop manufactured by company P in may = x
and by company Q in may = (1625 – x)
ATQ,
x × 38/100 + (1625 – x) × 60/100 = 766
=> 38x + 97500 – 60x = 76600 => 22x = 20900 => x = 950
Then 1625 – x = 675
and required difference = 950 – 675 = 275
12. B) No. of Laptops sold by company P in January = 450 × 32/100 = 144
No. of Laptop sold by company Q in July = 792 × 25/100 = 198
Therefore required % = (144/198 × 100)% = 72.72% ≈ 73%
13. B) No. of Laptop sold by company P in January = 450 × 32/100 = 144
Therefore, No. of Laptop sold by company Q in January = 2 × 144 – 2 = 286
Therefore, Required number = 286/44 × 100 = 650
14. D)
15. D) Required total = 260 × 45/100 + 250 × 24/100 = 117 + 60 = 177
16. B) 8 bag + 5 box = 25 × 13 = 325
4 bag + 7 box = 21 × 11 = 231
12 bag + 12 box = 556
Total cost of 18 bags and 18 boxes = 556 × 3 / 2 = 834
17. D) Let Harish age = x
Then
Harish brother’s age = x + 3
Harish mother’s age = x + 26
Harish sister’s age = (x + 3) + 4 = x + 7
Harish Father’s age = (x + 7) + 28 = x + 35
Age Harish father when Harish brother was born = x + 35 – (x + 3) = 32
18. E) Volume of cuboid = volume of two cubes together
36 × 18 × 3 = a^3 + 8a^3
a^3 = 216 => a = 6 cm
Surface area of the smaller cube = 6 × 6^2 = 216 cm^2
19. C) Work done by X in 1 hour = 1/8
Work done by Y in 1 hour = 1/10
Work done by Z in 1 hour = 1/12
Work done by X,Y and Z in 1 hour = 1/8 + 1/10 + 1/12 = 37/120
Work done by Y and Z in 1 hour = 1/10 + 1/12 = 22/120 = 11/60
From 9 am to 11 am, all the machines were operating.
Ie, they all operated for 2 hours and work completed = 2 × (37/120) = 37/60
Pending work = 1- 37/60 = 23/60
Hours taken by Y an Z to complete the pending work = (23/60) / (11/60) = 23/11
This is approximately equal to 2
Hence the work will be completed approximately 2 hours after 11 am ; ie around 1 pm
20. A) Total number of balls = 4 + 8 + 12 = 24
n(s) = 24C3 = 2024
Number of ways to select one ball of each colour
= n (E) = 4C1 × 8C1 × 12C1 = 4 × 8 × 12 = 384
P (E) = 384 / 2024 = 48 / 253
