Answer: D)
Explanation:
The pattern is as follows:
10 x 13 + 1 = 131
12 x 15 + 2 = 182
14 x 17 + 3 = 241
16 x 19 + 4 = 308
18 x 21 + 5 = 383
20 x 23 + 6 = 466

a) 106
b) 218
c) 26
d) 65
e) 157
Answer: C)
Explanation:
The pattern is as follows:
4 x 3 + 12 = 13
6 x 5 + 22 = 34
8 x 7 + 32 = 65
10 x 9 + 42 = 106
12 x 11 + 52 = 157
14 x 13 + 62 = 218
3. 9, 27.5, 139.0, 971.5, 8783.0, 96617.5
a) 8783.0
b) 139.0
c) 96617.5
d) 971.5
e) 27.5
Answer: D)
Explanation:
The pattern is as follows:
9 x 3 + 0.5 = 27.5
27.5 x 5 + 1.5 = 139.0
139.0 x 7 + 2.5 = 975.5
975.5 x 9 + 3.5 = 8783.0
8783.0 x 11 + 4.5 = 96617.5
4. 2085, 2078, 2046, 2011, 1963, 1900
a) 2078
b) 1900

d) 1963
e) 2011
Answer: A)
Explanation:
The pattern is as follows:
2085 - 42 + 1 = 2070
2070 - 52 + 1 = 2046
2046 - 62 + 1 = 2011
2011 - 72 + 1 = 1963
1963 - 82 + 1 = 1900

40 + 9 + 11 = 60
60 + 9 + 11 + 13 = 93
93 + 9 + 11 + 13 + 15 = 141
141 + 9 + 11 + 13 + 15 + 17 = 206
Directions (6 – 10): In the following questions, two statements numbered
I and II are given. On solving them, we get quantities I and II respectively.
Solve for both the quantities and choose the correct option.
6. Quantity I:
A boat goes from point P to Q downstream having a distance 120 m and comeback
to point T which is in the middle of P and Q in 6 secs then what is the speed
of boat(km/hr) if the speed of the stream is 10 m/sec?
Quantity II:
The ages of Raju and Rohan 5 years ago is in the ratio 3:2 and after 15 years
ratio of ages of Raju to Rohan is 17:13 then what is sum of the ages (years) of
Raju and Rohan 9 years from now?
a) Quantity I > Quantity II
b) Quantity I < Quantity II
c) Quantity I ≥ Quantity II
d) Quantity I ≤ Quantity II
e) Quantity I = Quantity II or the relation can't be
determined
Answer: E)
Explanation:
Quantity I:
Let speed of boat be Y m/sec.
Then,
Upstream speed = (Y - 10) m/sec.
Downstream speed = (Y + 10)
Thus,
120/(Y + 10) + 60/(Y - 10) = 6
120Y - 1200 + 60Y + 600 = 6(Y + 10)(Y
- 10)
180Y -600 = 6(Y2 - 100)
6Y2 - 180Y = 0
6Y(Y - 30)
Either Y = 0 or Y = 30
As speed of the boat cannot be zero
during the journey.
Speed of boat = 30 m/sec.
Required speed = (30 x 18/5) = 108
km/hr
Quantity II:
Let ages of Raju and Rohan 5 years
ago be 3Y and 2Y respectively.
Then,
(3Y + 20)/(2Y + 20) = 17/13
39Y + 260 = 34Y + 340
5Y = 80
Y = 16
Present age of Raju = (3 x 16) + 5 =
53 years
Present age of Rohan = (2 x 16) + 5 =
37
Required sum = (53 + 9) + (37 + 9) =
108 years
Hence, Quantity I = Quantity II
7. Quantity I:
Milk and water is filled into two vessels of same capacity in which water and
milk are in the ratio of 3 : 7 and 2 : 5. If the mixtures from both the vessels
are poured into another container then what will be the ratio of milk and water
in the new mixture?
Quantity II:
There is a mixture of 85 liter in which milk and water are in the ratio of 7 :
1. If 15 liters of water is poured into the mixture then what will the ratio of
milk and water in the resulting mixture?
a) Quantity I > Quantity II
b) Quantity I < Quantity II
c) Quantity I ≥ Quantity II
d) Quantity I ≤ Quantity II
e) Quantity I = Quantity II or the relationship cannot be
determined
Answer: B)
Explanation:
Quantity - I
Let the capacity of each vessel = n
liter
Amount of milk in 1st
vessel = n X 7/10 = 7n/10 liter
Amount of milk in 2nd
vessel = n X 5/7 = 5n/7 liter
Total amount of milk in both the
vessel = (7n/10 + 5n/7) liter = 99n/70 liter
Amount of water in the container
after mixing = 2n - 99n/70 = 41n/70 liter
Therefore, ratio of milk and water in
the resulting mixture = 99n/70 : 41n/70
=99 : 41
Quantity - II
Amount of water in the mixture = (85
X 1/8) liter = 10 5/8 liter
Amount of water in the mixture after
pouring 15 liters in it = (15 + 10 5/8) liter
=25 5/8 liter
amount of milk in the resulting
mixture = (100 - 25 5/8) liter = 74 3/8 liter
Hence required ratio = 74 3/8 ∶25 5/8 = 595 ∶205 = 119 ∶41
Hence, quantity II is higher that quantity
1.
8. Quantity I:
In how many ways a committee of 5 members can be formed from 5 men and 5 women
having at least 2 women?
Quantity II:
What is length (in meters) of train P which crosses a platform of length 280
meter and crosses train Q having length 360 meter running at a speed of 30
m/sec in opposite direction in 25.3 sec and 11.72 sec respectively?
a) Quantity I > Quantity II
b) Quantity I < Quantity II
c) Quantity I ≥ Quantity II
d) Quantity I ≤ Quantity II
e) Quantity I = Quantity II or the relation can't be
determined.
Answer: E)
Explanation:
Quantity I:
Committee of 5 member having 2 women
and 3 men = (5C2 x 5C3) = 100
Committee of 5 member having 3 women
and 2 men = (5C3 x 5C2) = 100
Committee of 5 member having 4 women
and 1 man = (5C4 x 5C1) = 25
Committee of 5 member having 5 women
= 5C5 = 1
Required possible number = (100 + 100
+ 25 + 1) = 226
Quantity II:
We have:
Let the length of train P be Y meter
Length of platform crossed by train P
= 280 meter
Speed of train P = (Y + 280)/25.3
Length of train Q = 360 meter
Speed of train Q = 30 m/sec
Relative speed of train P to Q = ((Y
+ 280)/25.3 + 30)
((Y + 280)/25.3 + 30) = (Y +
360)/11.72
(Y + 1039)/25.3 = (Y + 360)/11.72
11.72Y + 12177.08 = 25.3Y + 9108
13.58Y = 3069.08
Y = 226 meter
Hence, Quantity I = Quantity II
9. Quantity I:
In a circle of radius 84 cm, an arc subtends an angle of 108° at the center,
then what is the length (cm) of the arc?
Quantity II:
What is length (m) of a rectangular field having cost of flooring at the rate
of ₹4.8/m2 is ₹68040 and ratio of the length to breadth of the field is 9:7?
a) Quantity I > Quantity II
b) Quantity I < Quantity II
c) Quantity I ≥ Quantity II
d) Quantity I ≤ Quantity II
e) Quantity I = Quantity II or the relation cannot be
determined
Answer: A)
Explanation:
Quantity I:
Radius = 84 cm
Angle = 108°
Length of the Arc = 2ϖRθ/360° = (2 x
22/7 x 84 x 108/360)
Length of the Arc = 158.4 cm
Quantity II:
Let length of the field be 9Y and
Breadth be 7Y
Area = (L x B) = 68040/4.8 = 14175
By putting values of length and
breadth we get:
(9Y x 7Y) = 14175
63Y2 = 14175
Y = 15
Then, length = (15 x 9) = 135 m
Hence, Quantity I > Quantity II
10. Quantity I:
Rajeev invested a certain amount at the rate of 12% compounded annually and
obtained a compound interest of ₹5215.2 at the end of two years then what is
total simple interest earned at the end of 5 years on same amount if rate is
increased by 3%?
Quantity II:
Raghu sold a mobile phone at a 12% profit. Had he sold it for ₹738 more he
would get a profit of 18% then what was selling price for a profit of 25%?
a) Quantity I > Quantity II
b) Quantity I < Quantity II
c) Quantity I ≥ Quantity II
d) Quantity I ≤ Quantity II
e) Quantity I = Quantity II or the relation can't be
determined.
Answer: E)
Explanation:
Quantity I:
Let initial sum be ₹P.
Rate = 12%
Time = 2 years
CI = P x ((1 + R/100)2 -
1)
P x ((1 + R/100)2 - 1) =
5215.2
P x ((1 + 12/100)2 - 1) =
5215.2
P x 2544/10000 = 5215.2
P = 5215.2 x 10000/2544
P = ₹20500
Again,
Rate = (12 + 3) = 15%
Time = 5 years
SI = (P x R x T)/100
SI = (20500 x 15 x 5)/100 = 15375
Quantity II:
Let cost price of mobile be ₹Y
Then,
1.18Y - 1.12Y = 738
0.06Y = 738
Y = 738/0.06 = 12300
Required selling price = 12300 x
125/100 = ₹15375
Hence, Quantity I = Quantity II
