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

6, 19, 54, 167, 494, ?

((a))
1491
((b))
1553
((c))
1361
((d))
1642

Show Answer

Answer: ((a))

1491

The pattern followed is-

6 × 3 + 1 = 18 + 1 → 19

19 × 3 - 3 = 57 - 3 → 54

54 × 3 + 5 = 162 + 5 → 167

167 × 3 - 7 = 501 - 7 → 494

494 × 3 + 9 = 1482 + 9 → 1491

Hence, “1491” will complete the series.

In the following question, select the odd letters from the given alternatives.

((a))
AEI
((b))
IMQ
((c))
EIL
((d))
MQU

Show Answer

Answer: ((c))

EIL

AEI ⇒ A + 4 = E; E + 4 = I
IMQ ⇒ I + 4 = M; M + 4 = Q

3) EIL ⇒ E + 4 = I; I + 3 = L

MQU ⇒ M + 4 = Q; Q + 4 = U

Hence, “EIL” is odd letters among the given alternatives.

If 7 (110) 4 and 19 (930) 12, then what is the value of ‘A’ in 16 (A) 9 ?

((a))
580
((b))
600
((c))
640
((d))
700

Show Answer

Answer: ((b))

600

(7 + 4) = 11

⇒ 11 × (11 - 1) = 11 × 10 = 110

19 + 12 = 31

⇒ 31 × (31 - 1) = 31 × 30 = 930

Likewise, 16 + 9 = 25

⇒ 25 × (25 - 1) = 25 × 24 = 600

Therefore, value of A = 600.

In the following question, select the odd number from the given alternatives.

((a))
15 - 45
((b))
9 - 29
((c))
31 - 93
((d))
41 - 123

Show Answer

Answer: ((b))

9 - 29

The pattern followed is

15 × 3 → 45

31 × 3 → 93

41 × 3 → 123

So, 9 × 3 → 27

But 9 - 29, therefore it does not follow the pattern.

72 D 18 C 14 B 68 A 10 = - 4
((d))
12 A 6 B 3 C 4 D 3 = 14

Show Answer

Answer: ((d))

12 A 6 B 3 C 4 D 3 = 14

Symbol code	A	B	C	D
Meaning	+	-	×	÷

68 D 4 A 6 B 3 C 8 = 0

After converting,

⇒ 68 ÷ 4 + 6 - 3 × 8 = 17 + 6 - 24 = 1 (≠ 0 therefore false)

13 B 6 D 3 C 2 A 5 = 12

After converting,

⇒ 13 - 6 ÷ 3 × 2 + 5 = 13 - 4 + 5 = 14 (≠ 12 therefore false)

72 D 18 C 14 B 68 A 10 = - 4

After converting,

⇒ 72 ÷ 18 × 14 - 68 + 10 = 56 - 68 + 10 = 2 (≠ - 4 therefore false)

12 A 6 B 3 C 4 D 3 = 14

After converting,

⇒ 12 + 6 - 3 × 4 ÷ 3 = 18 - 4 = 14 (= 14 therefore true)

Hence, “12 A 6 B 3 C 4 D 3 = 14” is the correct equation.

Show Answer

Answer: ((a))

sec 12° = 1/cos12°

sec12° sin12° = 1/cos12° × sin12° = sin12°/cos12° = tan12° = cot (90 – 12) = cot78°

(sec x = 1/cos x, sin x/cos x = tan x, tan x = cot (90 – x))

tan38° = cot (90 – 38) = cot52°

(tan x = cot (90 – x)

Price of sugar increases by 30%. If expenditure increases by only 10%, then by how much percent consumption should decrease?

((a))
14.29
((b))
15.38
((c))
13.68
((d))
16.54

Show Answer

Answer: ((b))

15.38

Alternate MethodLet the initial price of sugar be Rs. 100 per kg and the initial consumption be 1kg.

Total initial expense = 100 × 1 = Rs. 100

The final price of sugar = 100 + 30 = Rs. 130 per kg

The final expense = 100 + 10 = Rs. 110

Final consumption = (110/130) × 100 = 0.8462

Percentage reduction in the consumption = [(1 - 0.8462)/1] × 100

⇒ 15.38%

∴ The consumption should be decreased by 15.38%.

Traditional method:

Let the initial price of sugar per unit be s.

Let the initial amount of consumption be a.

Let the final amount of consumption be ka.

⇒ Cost of a amount = as.

New rate of sugar = s + 30% = 13s/10

New price of consumption = (13s/10) × ka = 13kas/10

Percentage Increase in expenditure = (13kas/10 – as)/as = 100 × (13k/10 – 1) = 10

⇒ 13k/10 = 1/10 + 1 = 11/10

⇒ k = 11/13

Percentage Decrease in consumption = 100 × (ka – a)/a = 100 × (k – 1) = 100 × 2/13 = 15.38%.

Short trick:

Required price = 480/(0.8 × 1.2) = Rs. 500

Detailed solution:

Let the initial cost price of the product be x.

Selling price for A: SP = CP – Loss = x – 20% = 4x/5

Selling price for B: SP = CP + Profit = 4x/5 + 20% = 24x/25 = 480

⇒ x = 480 × 25/24 = Rs. 500.

Pipe A can fill a tank in 12 hours and Pipe B can fill the tank in 18 hours. If both the pipes are opened on alternate hours and if pipe B is opened first, then in how much time (in hours) the tank will be full?

((a))
14.5
((b))
14
((c))
15.5
((d))
15

Show Answer

Answer: ((a))

14.5

Given:

Time taken by A to fill the tank = 12 hours

Time taken by B to fill the tank = 18 hours

Concept used:

Total capacity = LCM

Efficiency = (Total Capacity)/(Total time)

Calculations:

Efficiency of pipe A = 1/12

Efficiency of pipe B = 1/18

If both opened together, work done in 2 hours = 1/18 + 1/12 = 5/36

So, 2 hour work = 5/36

After 14 hours (2 × 7), work done = 7 × 5/36 = 35/36.

Work left = 1 – 35/36 = 1/36.

Remaining work will be done by pipe B in h hours.

⇒ h/18 = 1/36

⇒ h = 1/2

Total time = 14 + 1/2 = 14.5 hours

∴ The total time is 14.5 hours

Total capacity = LCM (12, 18) = 36

Pipe	Time	Total capacity	Efficiency
A	12	36	36/12 = 3
B	18	36	36/18 = 2

If both opened together, work done in 2 hours = 3 + 2 = 5

After 14 hours, work done = 5 × 7 = 35

Work left = 36 – 35 = 1

Remaining work will be done by pipe B in h hours.

⇒ 2h = 1

⇒ h = 1/2

Total time = 14 + 1/2 = 14.5 hours

∴ The total time is 14.5 hours

Calculation:

x = 7 + 2 √10 = 5 + 2 + 2√2√5 = (√5 + √2)²

⇒ √x = √5 + √2

Then, 1/√ x = 1/(√5 + √2)

By multiple and dividing by (√5 - √2)

⇒ 1/√ x = 1× (√5 - √2)/(√5 + √2) × (√5 - √2)

⇒ 1/√ x = (√5 - √2)/3

⇒ (√x - 1/√x) = √5 + √2 – [1/(√5 + √2)] = √5 + √2 – [(√5 - √2)/3] = (2√5 + 4√2)/3

⇒ 2(√5 + 2√2)/3

Salary of A is 20% more than B and salary of B is 18% more than C. The salary of C is (approximately) how much percent less than A?

((a))
29.4%
((b))
32.5%
((c))
26.7%
((d))
28.1%

Show Answer

Answer: ((a))

29.4%

Let salary of C be x.

⇒ Salary of B = x + 18% = x + 18% = x + 18x/100 = 118x/100 = 59x/50

⇒ Salary of A = 59x/50 + 20% = 177x/125

Difference of salaries of A and C: 177x/125 – x = 52x/125

% Difference = 100 × (52x/125)/(177x/125) = 100 × 52/177 = 29.37 ~ 29.4%

The difference between circumference and the radius of a circle is 111 cm. What is the area (in cm²) of the circle?

((a))
469
((b))
1386
((c))
912
((d))

Show Answer

Answer: ((b))

1386

Circumference - radius = 2πr – r = r (2π – 1) = r(44/7 – 1) = 37r/7 = 111

⇒ r = 111 × 7/37 = 21 cm

Area = πr² = 22/7 × 21 × 21 = 1386 cm²

A, B and C can do a piece of work in 20, 24 and 30 days respectively. All three of them began the work together but B left 3 days before completion of the work. In how many days was the work completed?

((a))
7
((b))
10
((c))
12
((d))
9

Show Answer

Answer: ((d))

Let the work took n days to complete.

⇒ A and C worked for n days

⇒ B worked for n – 3 days

Total work done = n × (1/20 + 1/30) + (n – 3) × (1/24) = n × (1/20 + 1/30 + 1/24) – 3/24 = 1

⇒ n × (6 + 4 + 5)/120 – 15/120 = (15n – 15)/120 = (n – 1)/8 = 1

⇒ n = 9

A, B and C can do a piece of work in 20, 24 and 30 days

LCM of 20, 24 and 30

⇒ 120 unit total work

⇒ Efficiency of A = 6 unit

⇒ Efficiency of B = 5 unit

⇒ Efficiency of C = 4 unit

B left 3 days before

⇒ 3 × 5 = 15 unit

Total work = 120 + 15 = 135 unit

Together complete in 6 + 5 + 4 = 15 unit

⇒ 135/15

⇒ 9 days

∴ The work completed was 9 days.

Show Answer

Answer: ((a))

33.33%

Let Cost Price be c.

Let Selling Price be s.

20% Cost Price = 30% Selling Price

⇒ c/5 = 3s/10

⇒ c/s = 3/2

Loss% = 100 × (CP - SP)/CP = 100 × (c - s)/c = 100 × (1 - s/c) = 100 × (1 - 2/3) = 100/3 = 33.33%

((c))
Only I and III
((d))
All I, II and III

Show Answer

Answer: ((b))

Only II and III

We square both sides. Since all are greater than 1, the equality won’t change.

I. √7 + √3 > √5 + √5

⇒ (√7 + √3)² > (√5 + √5)²

⇒ 7 + 3 + 2√21 > 5 + 5 + 2√25

⇒ 10 + 2√21 > 10 + 2√25

⇒ √21 > √25

Clearly, this is false

II. √5 + √5 > √2 + √8

⇒ (√5 + √5)² > (√2 + √8)²

⇒ 5 + 5 + 2√25 > 2 + 8 + 2√16

⇒ 10 + 2√25 > 10 + 2√16

⇒ √25 > √16

Clearly, this is True

III. √5 + √5 > √7 + √3

⇒ (√5 + √5)² > (√7 + √3)²

⇒ 5 + 5 + 2√25 > 7 + 3 + 2√21

⇒ 10 + 2√25 > 10 + 2√21

⇒ √25 > √21

Clearly, this is True

∴ II and III are correct.

Show Answer

Answer: ((d))

sin x = 1/3

⇒ cos²x = 1 - 1/9

⇒ cos x = 2(2)^1/2/3 (sin²x + cos²x = 1)

cos y = 1/3

⇒ sin²y = 1 - 1/9

⇒ sin y = 2(2)^1/2/3 (sin²x + cos²x = 1)

sin (x + y) = sin x cos y + cos x sin y = 1/3 × 1/3 + 2(2)^1/2/3 × 2(2)^1/2/3 = 1/9 + 8/9 = 9/9 = 1.

What is the unit’s place of 12¹²³?

((a))
2
((b))
4
((c))

((d))
8

Show Answer

Answer: ((d))

Concept:

Unit digit: It is defined as the digit at once place of a given number. To calculate the unit digit, of a certain number with some power or product of numbers, we only have to focus on the digit at the one place of numbers.

Cyclicity: The concept of cyclicity is used to identify the last digit of the number. The cyclicity of any number is about the last digit and how they appear in a certain defined manner.

Procedure to find unit digit:

Step-1: Take the given power like the power of the unit digit of a given number.

Step-2: Divide the power by cyclicity of a given number

If it is completely divisible, then the unit digit will be digit at once place to the power its cyclicity.

If it is not divisible completely, replace the power with the remainder obtained, let xy (where x is a unit digit of a given number and y is remainder).

Step-3: Now, the unit digit will be obtained by simplifying xy.

Calculation:

12¹²³

Unit digit of the given number (base) is 3, and its cyclicity 4. Hence,

Step-1 123/4 ⇒ Remainder = 3

Step-2 (2)³ = 8

Unit digit of 12123 will be 8

Alternate Method

The last digit series of powers of 12 is 2, 4, 8, 6, 2.

∴ Numbers of form 12^{4k + 1}: 2

∴ Numbers of form 12^{4k + 2} : 4

∴ Numbers of form 12^{4k + 3} : 8

∴ Numbers of form 12^{4k + 4} : 6

∴ 12¹²³= 12^{4 × 30 + 3} will have 8 as unit digit.

Show Answer

Answer: ((d))

Given:

3x² – 9x + 3 = 0 and we have to find the value of (x + 1/x)³

Calculation:

3x2 – 9x + 3 = 0

⇒ x² - 3x + 1 = 0

⇒ x - 3 + 1/x = 0 [Dividing both sides by x]

⇒ x + 1/x = 3

Now,

(x + 1/x)³ = (3)³ = 27

∴ The required value of (x + 1/x)³ is 27.

Amit goes to his office by car at the speed of 80 km/hr and reaches 15 minutes earlier. If he goes at the speed 60 km/hr, he reaches 15 minutes late. What will be the speed (in km/hr) of the car to reach on time?

((a))
478/7
((b))
476/7
((c))
480/7
((d))
484/7

Show Answer

Answer: ((c))

480/7

Short Trick:

The ratio of speed is inversely proportional to the ratio of time taken

⇒ the ratio of speed = 80 : 60 = 4 : 3

⇒ The ratio of time taken = 3 : 4

4 units - 3 units = 15 + 15 = 30 minutes

⇒ 1 units = 30 minutes

Total distance = 90/60 × 80 = 120 km

Actual time taken = 90 + 15 = 105 min

∴ Actual speed = 120 × 60/105 = 480/7

Detailed Solution:

Let the speed to reach on time be s.

Let the distance to office be d.

Time taken by car at 80 km/hr = x = d/80

Time taken by car at 60 km/hr = y = d/60

Time taken by car at s km/hr = z = d/s

Given: x = z – 15/60, y = z + 15/60

⇒ d/80 = d/s – 15/60 = d/s – 1/4 ⇒ d(1/80 – 1/s) = -1/4

⇒ d/60 = d/s + 15/60 = d/s + 1/4 ⇒ d(1/60 – 1/s) = 1/4

Dividing the two equations, we get

(1/80 – 1/s)/(1/60 – 1/s) = -1

⇒ 1/80 – 1/s = 1/s – 1/60

⇒ 2/s = 1/80 + 1/60 = (7/240)

⇒ s = 2 × 240/7 = 480/7 km/h

Show Answer

Answer: ((d))

necessities

The word here should be such that is a common part of life and cannot be eliminated at any cost. Thus ‘necessities’ which means ‘needs’ is the correct word here. The other words do not fit here.The word ‘passions’ means ‘strong and barely controllable emotion.’

162

that is will power honest ______ and some small initiatives

((a))
assurance
((b))
factor
((c))

((d))
inclination

Show Answer

Answer: ((d))

inclination

The word in the blank must be a noun that goes with the adjective ‘honest.’ Thus ‘inclination’ which means ‘propensity’ which is similar to will power fits here correctly. The other words do not convey any meaning here. ‘Assurance’ means ‘a positive declaration intended to give confidence’ and ‘factor’ means ‘a circumstance, fact, or influence that contributes to a result.’

163

It's a very ______ element of our environment.

((a))
contradictory
((b))

The word ‘no’ is the correct word as the next sentence has the word ‘if’. It has a condition which conveys the meaning that no big step is required to save the environment. Thus ‘huge’ which means ‘big’ and ‘sufficient’ which means ‘adequate’ would not fit here.

165

make some time for ______ the well being of the environment

((a))
ensuring
((b))
resulting
((c))

Show Answer

Answer: ((b))

The correct answer is: 2.

Key Points

'rather' and 'than' are correlative conjunctions i.e., they are always used in pair.
The preposition 'to' never agrees with the conjunction 'rather'.
For example: I would rather watch a movie than sleep.
Similarly, in this question, the use of the preposition ‘to’ after ‘rather' is incorrect.
Removing 'to' after 'rather' would make the sentence grammatically correct.

Therefore, the correct answer is: I would rather die than beg.

Some of the important Correlative Conjunctions are:
Either….or
Neither….nor
Hardly….when
Scarcely….when
Both…and
If…then
Not only….but also

This is the same dog ______ was running on the road.

((a))
whom
((b))
who
((c))
which
((d))
that

Show Answer

Answer: ((d))

that

‘Who’ and ‘whom’ are used in cases of human beings and not animals.The correct word here is ‘that’ and not ‘which’.

A defining clause (also called an essential clause or a restrictive clause) gives information essential to the meaning of the sentence. That is used in defining clauses. Here’s an example:

My bike that has a broken seat is in the garage.

Which introduces non-defining clauses. Unlike defining clauses, non-defining clauses (also called nonessential or nonrestrictive clauses) don’t limit the meaning of the sentence. You might lose interesting details if you remove them, but the meaning of the sentence wouldn’t change. Sometimes, these phrases are set off by commas.

My bike, which has a broken seat, is in the garage.

Thus option 4 is the correct answer.
