In the following question, select the missing number from the given series.

283, 94, 31, 10, ?

((a))
3
((b))
4
((c))
5
((d))
7

Show Answer

Answer: ((a))

The pattern followed is -

⇒ 3 × 3 = 9 + 1 = 10

⇒ 10 × 3 = 30 + 1 = 31

⇒ 31 × 3 = 93 + 1 = 94

⇒ 94 × 3 = 282 + 1 = 283

Thus, “3” is the missing number.

In each of the following question below are given some statements followed by some conclusions. Taking the given statements to be true even if they seem to be at variance from commonly known facts, read all the conclusions and then decide which of the given conclusion logically follows the given statements.

Statements:

I. Some men are hardworking.

II. No blue is a advocate.

III. Some blue are men.

Conclusions:

I. Some blue are hardworking.

II. Some men are advocate.

III. Some blue are not hardworking.

IV. Some men are not advocate.

((a))
Only conclusion (IV) follows
((b))
Only conclusion (II) and (IV) follow
((c))
Only conclusion (I), (II) and (IV) follow
((d))
Only conclusion (III) follows

Show Answer

Answer: ((a))

Only conclusion (IV) follows

The possible Venn diagram is:

Explanation:

I. Some blue are hardworking → It is not a definite case, hence it is false.

II. Some men are advocate → No direct relation established between the two, hence it is false.

III. Some blue are not hardworking → No direct relation established between the two, hence it is false.

IV. Some men are not advocate → The part of blue which are men are not advocate thus, relation is established, hence, it is true.

Thus, Only conclusion (IV) follows.

If 7² A 7 B 9 = 16 and 5² A 5 B 7 = 12, then 9² A 3 B 8 = ?

((a))
17
((b))
92
((c))
86
((d))
35

Show Answer

Answer: ((d))

7²** A 7 B 9 = 16

⇒ 7² ÷ 7 + 9 = 7 + 9 = 16

5²** A 5 B 7 = 12

⇒ 5² ÷ 5 + 7 = 5 + 7 = 12

9²** A 3 B 8 = ?

⇒ 9² ÷ 3 + 8 = 27 + 8 = 35 = ?

Hence, “35” is correct answer.

((a))
×, +, = and ÷
((b))
+, +, = and ×
((c))
×, -, = and ×
((d))
+, ×, = and ×

Show Answer

Answer: ((c))

×, -, = and ×

1) ×, +, = and ÷

⇒ 32 × 2 + 8 = 14 ÷ 4

⇒ 72 = 3.5 (False as LHS ≠ RHS)

2) +, +, = and ×

⇒ 32 + 2 + 8 = 14 × 4

⇒ 42 = 56 (False as LHS ≠ RHS)

3) ×, -, = and ×

⇒ 32 × 2 - 8 = 14 × 4

⇒ 56 = 56 (True as LHS = RHS)

4) +, ×, = and ×

⇒ 32 + 2 × 8 = 14 × 4

⇒ 48 = 56 (False as LHS ≠ RHS)

Hence, “×, -, = and ×” is the correct answer.

Statements:

I. All men are scholars.

II. Some scholars are advocate.

Conclusions:

I. All scholars are men.

II. Some men are advocate.

III. No men is advocate.

((a))
No conclusion follows
((b))
Only conclusion II follows
((c))
Only conclusion III follows
((d))
Either conclusion II or conclusion III follows

Show Answer

Answer: ((d))

Either conclusion II or conclusion III follows

The possible Venn diagram:

Explanation:

I. All scholars are men → Not possible as all men are Scholars, hence it is false.

II. Some men are advocate → It is not a definite case, hence it is false.

III. No men are advocate → It is not a definite case, hence it is false.

But Conclusion II and III make a complementary pair.

Thus, Either conclusion II or conclusion III follows

In ΔPQR we have,

∠QPR = 55° and ∠QRP = 75°

∴ ∠PQR = 180° - (55° + 75°) = 180° - 130° = 50°

∴ ∠POR = 2 × ∠PQR = 2 × 50° = 100°

In ΔOPR,

∠OPR = ∠ORP [∵ OR = OP, both are Circum radius]

∴ ∠OPR + ∠ORP = 180° - 100° = 80°

⇒ ∠OPR + ∠OPR = 80°

⇒ 2∠OPR = 80°

⇒ ∠OPR = 40°

Show Answer

Answer: ((d))

√3

From problem,

⇒ sin (2x + 3y) = √3/2

⇒ sin (2x + 3y) = sin 60°

⇒ 2x + 3y = 60° ----(1)

From problem,

⇒ cos (4x - 3y) = √3/2

⇒ cos (4x - 3y) = cos 30°

⇒ 4x - 3y = 30° ----(2)

From (1) + (2) we get,

⇒ 2x + 4x = 60° + 30°

⇒ 6x = 90°

⇒ x = 15°

Putting the value of x in (1) we get,

⇒ 2 × 15° + 3y = 60°

⇒ 3y = 60° - 30°

⇒ y = 10°

∴ tan (6x - 3y)

⇒ tan (6 × 15° - 3 × 10°)

⇒ tan 60°

⇒ √3

Answer: ((b))

∠BAE = 30°

∴ ∠DAE = ∠BAE = 30° [∵ AE is bisector of ∠BAD]

∴ ∠BAD = ∠BAE + ∠DAE = 30° + 30° = 60°

∴ ∠CAD = ∠BAD = 60° [∵ AD is bisector of ∠BAC]

∴ ∠CAE = ∠CAD + ∠DAE = 60° + 30° = 90°

In ΔCAE we have,

∠CAE = 90°

AE = 9 cm

EC = 15 cm

∴ AC = √ (15² - 9²) = √(225 - 81) = 12 cm

∴ Area of ΔCAE,

⇒ ½ × AE × AC

((b))
36000
((c))
40000
((d))
72000

Show Answer

Answer: ((c))

40000

Let, the amount = Rs. x

When compounded annually,

Rate = 18%

Number of years = 1

∴ Interest = x (1 + 18/100) - x

⇒ 1.18x – x

⇒ Rs. 0.18x

When compounded half yearly,

Effective Rate = (18/2) = 9%

Number of half years = 1 × 2 = 2

∴ Interest = x (1 + 9/100)² - x

⇒ x × (1.09)² – x

⇒ 1.1881x – x

⇒ Rs. 0.1881x

According to problem,

⇒ 0.1881x – 0.18x = 324

⇒ 0.0081x = 324

⇒ x = 324/0.0081

⇒ x = 40000

∴The amount lent = Rs. 40000

135/7

Let, upstream speed = x km/h and downstream speed = y km/h

A boat goes 2 km upstream and 3 km downstream in 20 minutes.

According to problem,

⇒ 2/x + 3/y = 20/60

⇒ 120/x + 180/y = 20

⇒ 240/x + 360/y = 40 ……….. (1) [Multiplying by 2 on both sides]

The boat goes 7 km upstream and 2 km downstream in 53 minutes.

According to problem,

From (2) – (1) we get,

⇒ 1260/x – 240/x = 159 – 40

⇒ 1020/x = 119

⇒ x = 1020/119

⇒ x = 60/7

Putting the value of x in (1) we get,

⇒ 240 × (7/60) + 360/y = 40

⇒ 360/y = 40 – 28

⇒ 360/y = 12

⇒ y = 360/12

⇒ y = 30

∴ Upstream speed = (60/7) km/h and downstream speed = 30 km/h

∴ Speed of the boat in still water = [(60/7) + 30]/2 = (270/14) km/h = 135/7 km/h

If the perimeter of a rhombus is 40 cm and one of its diagonal is 16 cm, then what is the area (in cm²) of the rhombus?

((a))
72
((b))
48
((c))
96
((d))
192

Show Answer

Answer: ((c))

ABCD is the rhombus.

Perimeter = 40 cm

∴ Side = 40/4 = 10 cm

∴ AB = BC = CD = DA = 10 cm

BD = 16 cm

Diagonals of a rhombus diagonally bisects each other,

In AEB we have,

∠AEB = 90°

∴ BE = BD/2 = 8 cm

AB = 10 cm

∴ AE = √ (10² – 8²) = √(100 – 64) = 6 cm

∴ AC = 2 × AE = 2 × 6 = 12 cm

∴ Area of the rhombus,

⇒ ½ × 16 × 12

⇒ 96 cm²

If the height of cylinder is increased by 35% and radius is increased by 10%, then what will be the percentage increase in curved surface area of cylinder?

((a))
46.5
((b))
45
((c))
48.5
((d))
49.7

Show Answer

Answer: ((c))

48.5

Let, original height = h

Original radius = r

∴ Curved surface area of the cylinder = 2πrh

After 35% increase, height = h + h × 35/100 = 1.35h

After 10% increase, radius = r + r × 10/100 = 1.1r

∴ New curved surface area of the cylinder = 2π × 1.1r × 1.35h = 2.97πrh

∴ Percentage increase in the curved surface area of the cylinder = [(2.97πrh - 2πrh)/2πrh] × 100

⇒ 0.97/2 × 100% = 48.5%

135

If the radius of a circle is increased by 50%, then what will be the percentage increase in the area of circle?

((a))

175

Show Answer

Answer: ((b))

125

Let, original radius = r

∴ Original area = πr²

Radius after increase of 50% = r + r × 50/100 = 1.5r

∴ New area = π × (1.5r)²= π × 2.25r²

∴ percentage increase in the area of circle = [(2.25πr² - πr²)/πr²] × 100

⇒ 1.25/1 × 100%

⇒ 125%

⇒ tan θ = √3

⇒ tan𝜃 = tan 60°

⇒ θ = 60° ----(1)

From problem we get,

⇒ 𝜃 + ϕ = π/2

⇒ θ + ϕ = 90° ----(2)

From (1) and (2) we get,

⇒ ϕ = 90° - 60°

⇒ ϕ = 30°

∴ cos (𝜃 - ϕ)

⇒ cos (60° - 30°)

⇒ cos 30°

⇒ √3/2

Average of 36 results is 18. If 2 is subtracted from each result, then what will be the new average of the results?

((a))
9
((b))
16
((c))
17
((d))
17.5

Show Answer

Answer: ((b))

Average of 36 results = 18

∵ Sum of 36 results = 36 × 18 = 648

Let, new average = x

According to the problem,

⇒ 36x = 648 - 36 × 2

⇒ 36x = 648 - 72

⇒ 36x = 576

⇒ x = 16

∴ New average = 16

TRICK:

If same change is made in each of the Quantity then the same change also appears in the Average.

here for Example-

2 is subtracted from each Quantity than for final average we can directly subtract 2 from average to calculate final average

= 18 - 2 = 16

⇒ 165/x – 165/1.25x = 40/60

⇒ 165/5x = 2/3

⇒ 10x = 495

⇒ x = 49.5

∴ Difference in the speed of train and car,

⇒ 1.25x – x

⇒ 0.25x

GIVEN:

A alone can complete the work in = 10 days

B alone can complete the work in = 12 days

C alone can complete the work in = 15 days

Total earning = Rs. 4500

FORMULA USED:

Share of C = Ratio of C / Sum of ratio × 100

CALCULATION:

A alone can complete the work in = 10 days

∴ A’s 1 day’s work = 1/10

B alone can complete the work in = 12 days

∴ B’s 1 day’s work = 1/12

C alone can complete the work in = 15 days

∴ C’s 1 day’s work = 1/15

∴ Ratio of work of A, B and C,

⇒ (1/10) ∶ (1/12) ∶ (1/15)

⇒ 60 × 1/10 ∶ 60 × 1/12 ∶ 60 × 1/15

⇒ 6 ∶ 5 ∶ 4

Total earning = Rs. 4500

∴ Share of C,

⇒ 4500 × [4/(6 + 5 + 4)]

⇒ 4500 × 4/15

⇒ 1200

∴ Share of C = Rs. 1200

Improve the bracketed part of the sentence.

No sooner (he had returned home then) his grandparents felt happy.

((a))
did he return home than
((b))
he had returned home than
((c))
had he returned home when
((d))
no improvement

Show Answer

Answer: ((a))

did he return home than

Here the correct answer is Did he return home than.

Key Points

'No sooner' and 'than' are correlative conjunctions i.e., they are always used in pairs.
For example: No sooner did I reach the station than the train left. (Hence, options 3) and 4) are incorrect as 'than' is not used.)
When we use an adverb with negative meaning (e.g. never, scarcely, hardly, no sooner) in front position for emphasis, we interchange the subject and the verb. The verb is used before the subject, in this case. This is the rule of inversion.
The format of 'No sooner…than' is: No sooner + did + Subject + V1 + than + rest of the sentence.
For example: No sooner did the bell ring than I opened it.
Only option 1) follows the above mentioned structure of the sentence, which is grammatically correct.

Therefore, the correct answer is: No sooner did he return home than his grandparents felt happy.

A passage is given with five questions following it. Read the passage carefully and select the best answer to each question out of the given four alternatives.

Morality is identified with ethics and symbolizes the doctrine of actions right or wrong. Politics is the notion of expediency and need not always by right. If something is wrong and merely expedient; it cannot be moral. To put it the other way round, whatever is right or just, or born of sound principles and designed to promote the social good, cannot be immoral. There appears a basic confrontation between morality and politics.

The great Utilitarian Bentham maintains that, "The greatest happiness of the greatest numbers is the foundation of morals and legislation." However, often it is found that there is a conflict between convictions and principles, on the one hand, and expediency on the other. Thus, morality and politics do not often go hand in hand, for politics is based upon expediency and its foundations are of 'power'. Power corrupts, and absolute power corrupts absolutely, said Lord Acton and surely enough,corruption cannot breed morality. While morality establishes justice and fair play, politics, as Sidney Hillman opines, is the science of who gets what, when and why.Morality requires an equitable distribution of wealth, goods and commodities and opportunities while politics reeks of opportunism, of grabbing and seizing whatever you can, irrespective of the needs and claims of others. Morality stands for justice of all, while the politicians are generally selfish and self-seeking. All this goes to show that morality and politics do not go together. Any democracy today merely reiterates the story of a struggle for power, for perpetuating the safe citadel, and for keeping at bay any kind of opposition or criticism. Political parties symbolize nothing more than a bitter rivalry and quest for power by ousting all other rivals. Means and methods are thrown to the winds as long as selfish short-term aims and objectives are duly achieved and fulfilled.

On the other hand, morals and morality do not permit the adoption of just any means. Values are the foremost consideration. The traditional values which are in themselves moral, and symbols of rectitude and righteousness, have undergone a radical change in our modern times. Most of the cherished old values and morals are being sacrificed at the altar of circumstances for the sake of expediency and quick gains. The current political atmosphere and scene in most parts of the world is devoid of moral ardour and sound convictions.Opportunism has become a matter of faith with politicians or those having even a slight bent of mind towards politics. Patriotism has come to be identified with politics and well illustrates Johnson's dictum of patriotism being the last refuge of scoundrels.

165

Which of the following is 'CORRECT' with respect to the passage?

((a))
current politics has moral ardours and sound convictions
((b))
traditional values are not the symbol of rectitude and righteousness

Show Answer

politicians are selfish and self-seeking

The correct answer is 'politicians are selfish and self-seeking'

Key Points

Also, the traditional values which are in themselves moral, and symbols of rectitude and righteousness, denotes that traditional values are symbol of rectitude and righteousness. Word rectitude means rightness of principle or conduct; moral virtue. This makes option 2 incorrect.
Since, it is mentioned that in Sidney Hillman opinion, politics is the science of who gets what, when and why. No mention of how is given in the passage. This makes option 3 incorrect.
But the seventh line of the second paragraph in the given passage states that - 'Morality stands for justice of all, while the politicians are generally selfish and self-seeking.
This makes option 4 the CORRECT statement with respect to the passage.

But the passage states in the first line of the third paragraph - 'On the other hand, morals and morality do not permit the adoption of just any means.'
