**Solutions:**

**1. D)**Series is 2

^{3}- 1, 4

^{3}-3, 6

^{3}- 5, 8

^{3}- 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 ×1

^{2}+ 1, ×2

^{2}+ 3, ×3

^{2}+ 5, ×4

^{2 }+ 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
