The pattern followed here is,

1 + 2 → 3 + 3 → 6 + 5 → 11 + 7 → 18 + ?

In the given series prime numbers are added in the previous number,

So, 11 which is next prime number after 7 will be added to 18.

→ 18 + 11 = 29

Hence, next number in the series is 29.

The pattern followed here is:

JKLM : IIII

→ J – 1 = I, K – 2 = I, L – 3 = I, M – 4 = I

Same pattern will be followed to answer the question:

→ P – 1 = O, Q – 2 = O, R – 3 = O, S – 4 = O

Clearly, the related alternative is OOOO.

Table 1:

3 + 2 + 5 + 4 + 1 + 7 = 22

Table 2:

1 + 2 + 7 + 6 + 4 + 2 = 22

Clearly, sum of numbers of Table 3 will also be 22,

Table 3:

2 + 1 + 3 + 11 + 1 + ? = 22

? = 22 – 18

= 4

Hence, missing number in the table is 4.

The least possible Ven Diagrams for the given Statements is as follows:

Conclusions: 

I. Some pencils are erasers → false.

II. All erasers are pens → false.

Hence, neither conclusion I nor II follows.

Clearly, answer will be option 3.

The logic followed here is, 

Hence, the value of A is 16.

1. 11 – 121 → (11)² = 121

2. 13 – 169 → (13)² = 169

3. 19 – 391 → (19)² = 361

4. 21 – 441 → (21)² = 441

Clearly, 19 – 391 is odd pair of numbers.

Clearly, 6 cardboard boxes are not white.

1. 10, 14, 00, 59, 97 → R, R, E, A, P

2. 31, 33, 41, 67, 76 → G, R, E, T, M

3. 43, 01, 23, 95, 89 → G, R, E, A, T

4. 24, 42, 11, 86, 95 → G, R, L, A, A

Hence, ‘GREAT’ will be represented by ‘43, 01, 23, 95, 89’.

The pattern followed here is,

4 : 17 → 4 × 4 + 1

= 16 + 1 → 17

Same pattern will be followed:

→ 7 × 7 + 1 = 50

Hence, the related alternative is 50.

1. Rope → Improvement → can be formed.

2. Trim → Improvement → can be formed.

3. Important → Improvement → cannot be formed as there is only one t, and letter a is not given in the word Improvement.

4. Prove → Improvement → can be formed.

Clearly, Important cannot be formed.

On observing the options wee can say that option 1 will complete the figure as it has two squares at its rightmost side and a half oval to its downward.

Large triangles in EFGH: EGH, GHF, EFH, FEG, FJH, HGK, GJE, EJF

Small triangles in EFGH: ELJ, EIJ, FIJ, FJM, MJH, HKJ, GJK, GLJ

Hence, there are total 36 triangles.

Clearly, the given question figure is hidden in option 2.

A Book is made of Pages so, the Continents are collection of Countries inside it.

1. FHJ → F + 2 → H + 2 = J

2. LNQ → L + 2 → N + 3 = Q

3. JLN → J + 2 → L + 2 = N

4. NPR → N + 2 → P + 2 = R

Clearly, LNQ is the odd one.

The pattern followed in the given series is as follows:

 A + 4 → E + 4 → I + 4 → M + 4 → Q

Hence, next letter in the given series will be Q.

Let the weight of Book 2 is x grams

Weight of Book 1 = 2x (given: twice as heavy as Book 2)

Weight of Book 3 = x/2 (given: half of Book 2's weight)

Weight of Book 4 = x + 60 & 2x – 60 (given)

→ x + 60 = 2x – 60

→ 120 grams = x (weight of Book 2)

Weight of Book 2 = 2x → 2 × 120

= 240 grams

Weight of Book 3 = x/2 → 120/2

= 60 gramsWeight of Book 4 = x + 60 → 120 + 60

= 180 grams

Clearly, Book 1 is heaviest among all the books.

Given equation: 44 M 24 K 56 L 14 J 60 = ?

On replacing the letters:

44 - 24 × 56 ÷ 14 + 60 = ?

→ 44 - 96 + 60

→ 8

Hence, answer is 8.

Hence, odd pair is Sad : Hopeful.

Minamata disease, sometimes referred to as Chisso-Minamata disease, is a neurological syndrome caused by severe mercury poisoning.

CONCEPT:

Pascal's Law:

• It states that if the gravity effect is neglected, the pressure at every point of liquid in the equilibrium of rest is the same.
• The increase in pressure at one point of the enclosed liquid in an equilibrium of rest is transmitted equally to all other points of the liquid and also to the walls of the container, provided the effect of gravity is neglected.

EXPLANATION:

• Pascal's principle states that pressure applied to fluids is equally transmitted in all directions, to all parts of the fluid and to all parts of a container.
• Scuba divers must also understand this principle as at a depth of 10 meters underwater, the pressure is twice the atmospheric pressure at the sea surface, and increases by about 100 kPa for each increase of 10 m depth. Therefore option 4 is correct.

Explanation:

Estrogen (American English) or oestrogen (British English) is the primary female sex hormone as well as a medication.

• It is responsible for the development and regulation of the female reproductive system and secondary sex characteristics.
• Estrogens are synthesized in all vertebrates as well as some insects.
• Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history.
• While estrogen levels are significantly lower in males compared to females, estrogens nevertheless also have important physiological roles in males.

Progesterone and estrogen are two female sex hormones released into woman's ovary by the bloodstream.

• Testosterone is a male sex hormone produced by testes also called testicles.

We can do this question by checking the options

Let x = - 4

⇒ √{5 (- 4) – 6}, negative term in the square root which is not correct

⇒ option 1 is not Ans

Let x = 0

⇒ √{0 – 6} = √(- 6), negative term in the square root which is not correct

⇒ option 2 is not Ans

Let x = 2

⇒ √{5 (2) – 6} + √{5 (2) + 6}

⇒ √4 + √16 = 2 + 4 = 6 = RHS

⇒ option 3 is Ans

Let x = - 4

⇒ √{5 (4) – 6} + √{5 (4) + 6} , which is not equal to 6

⇒ option 4 is not Ans

∴ the Ans is x = 2

Let ∠ABC be x then ∠BAC = 2x

Using Exterior angle property

⇒ ∠CAB + ∠ABC = ∠ ACD

⇒ 2x + x = 114

⇒ x = 38

⇒ ∠BAC = 2x = 2 × 38 = 76

∴ ∠BAC is 76

Since we know that ∠POA = ∠POB = 50

⇒ ∠AOB = 50 + 50 = 100

Now in quadrilateral PAOB

⇒ ∠APB + ∠PAO + ∠AOB + ∠OBP = 360

⇒ ∠BPA = 360 - 90 - 90 - 100 = 80 (∵∠PAO = 90 and ∠AOB = 90 because they are tangent)

∴ ∠APB = 80

Perimeter of tyre can be given as = πD = (22/7) × 21

⇒ Perimeter of tyre = 66 cm = .00066 km

Distance covered by cyclist in 45 minutes or 45/60 hrs can be given as

⇒ 16.5 × (45/60)

⇒ 16.5 × 3/4

Revolution can be given as total distance covered by cycle/perimeter of tyre

⇒ 16.5 × 3/(4 × .00066) = 18750

∴ The total revolutions are 18750

Let the amount of tea having rate of Rs. 240/kg be a kg and that of tea having rate of 280/kg be b kg

Total amount at which it is sold = 240a + 280b

And the rate for mixture is given as Rs. (240a + 280b)/(a + b) /kg

After 20% profit on this rate it is equal to 324

⇒ {(240a + 280b)/(a + b)} × (1 + 20/100) = 324

⇒ 240a + 280b = 270a + 270b

⇒ 10b = 30a

⇒ a/b = 1/3

∴ The required ratio is 1 : 3

Given that 3/5^th of the work is done by A and B, so the work done by C is given as

⇒ 1 - 3/5 = 2/5^th of the total work

⇒ Share of C is 2/5^th of Rs 5000

⇒ C’s share = 2 × 5000/5 = Rs. 2000

∴ The share of C is Rs. 2000

Volume of cone is (1/3)πr²h

⇒ Volume of cone = (1/3) π (9)² × 36 = 972 π cm³

Volume of Cylinder is = πr²h

⇒ Volume of cylinder = π (9)² × 9 = 729 π

Volume wasted can be given as Volume of cone – volume of cylinder

⇒ 972 π - 729 π = 243 π

⇒ Percentage of wastage material is 243 π × 100/972 π = 25%

∴ The wasted material is 25%

Short trick∶

Put A = 0

⇒ sec A = 1 and tan A = 0

Now put this in the required expression

⇒ (sec⁴ A – tan² A) - (tan⁴ A + sec² A)

⇒ (1) - (1) = 0

∴ The simplified value of (sec⁴ A - tan² A) - (tan⁴ A + sec² A) is 0

Detailed solution∶

(sec4 A - tan2 A) - (tan4 A + sec2 A)

⇒ (sec4 A - tan4 A) - (tan2 A + sec2 A)

⇒ (sec2 A - tan2 A)(sec2 A + tan2 A) - (tan2 A + sec2 A)

⇒ (sec2 A + tan2 A) - (tan2 A + sec2 A)

⇒ 0

Total number of mobile phone sold in 2014 can be given as

⇒ 4 + 4.5 + 6 + 7.5 = 22

Total number of mobile phone sold in 2016 can be given as

⇒ 7.5 + 6 + 7.5 + 9.5 = 30.5

Increase in sales is 30.5 – 22 = 8.5

⇒ percentage increase in sale is given as = 8.5 × 100/22 = 38.63%

∴ the percentage increase in the sale is 38.63%

Given that ∠QPT = 30

⇒ ∠TPS = 30 (∵ PT is angle bisector of ∠QPS)

⇒ ∠QPS = 30 + 30 = 60 = ∠SPR (∵ PS is angle bisector of ∠QPR)

Now the ∠TPR = 30 + 60 = 90, therefore the triangle PTR is right angled triangle

Using Pythagoras theorem in triangle PTR

⇒ TR² = TP² + PR²

⇒ 15² - 9² = PR²

⇒ PR = 12

⇒ Area of triangle = ½ × (TP) × (PR)

⇒ Area of triangle = 1/2 × 12 × 9 = 54 cm²

∴ Area of triangle is 54 cm²

The given figure can be drawn as,

∵ PQ = PR = 18 cm, ∆PQR is an isosceles triangle

⇒ ∠PQR = ∠PRQ = x (let)

∵ AB is parallel to PR and AC is parallel to PQ,

⇒ ∠QAB = ∠PRQ = x (corresponding angles)

⇒ ∠RAC = ∠PQR = x (corresponding angles)

Also, QA = AR

Hence, ∆QAB and ∆RAC are isosceles and congruent (AAS)

⇒ QB = AB = AC = CR

Also,

⇒ ∠PCB = ∠PRQ = x (corresponding angles)

⇒ ∠PBC = ∠PQR = x (corresponding angles)

Hence, PB = QB = PC = CR = 18/2 = 9 cm

∴ Perimeter of quadrilateral ABPC = AB + PB + PC + AC = 4(9) = 36 cm

Let its cost price be Rs. x

From the problem’s statement

⇒ 540 - x = x – 370

⇒ 2x = 910

⇒ x = 455

If it was sold for Rs. 910

⇒ Profit = 910 - 455 = 455

⇒ Profit % = Profit × 100/CP = 455 × 100/455

⇒ Profit % = 100

∴ The profit percentage will be 100%

Total sale of 2015 = 5.5 + 5 + 6.5 + 8.5 = 25.5

Total sale in 2016 = 7.5 + 6 + 7.5 + 9.5 = 30.5

⇒ Percentage increase in the sale = (30.5 - 25.5) × 100/25.5

⇒ Percentage increase in sale is 19.6%

Sale in 2017 is 19.6% more of that in 2016

⇒ Sale in 2017 = 30.5 × (1 + 19.6/100) = 30.5 × 1.196

⇒ Sale in 2017 = 36.478

Average sale can be given as

⇒ 36.478/4 = 9.1195

Since we know that the scale given is × 1000

⇒ average sale = 9.1195 × 1000 = 9119.5

∴ the average sale is 9120 units

Since we know that LCM of 2, 3 and 7 is 42

And the 1^st number just after 300 and divisible by 42 can be written as 42 × 8 = 336

And the Last number divisible by 42 and less than 700 can be written as 42 × 16 = 672

⇒ Numbers between 700 and 300 which are divisible by 42 are 16 - 8 + 1 = 9

∴ Numbers from 300 to 700 which are divisible by 2, 3 and 7 are 9

The percentage of students who have passes both subjects is given as

⇒ Percentage of students pass in history + Percentage of students who pass in Hindi + percentage of students who failed in history and Hindi – total percentage of students(i.e 100%)

⇒ Percentage of students who have passed in both subjects = 65 + 55 + 5 – 100 = 25%

∴ The percentage of students who have passed in both subjects is 25%

Alternate Method 

Here, Total = 100x

ax = Percentage of students pass in history

cx = Percentage of students pass in Hindi

bx = Percentage of students who passed both subjects

dx =  Percentage of students who did not pass any subject 

We can see that, 

⇒ ax + cx - bx + dx = 100x

⇒ 65x + 55x - b + 5x = 100x 

⇒ 125x - bx = 100x

⇒ - bx = 100x - 125x = -25x

⇒ b = 25

∴ The percentage of students who have passed both subjects is 25%

Cot A can be written as cot A = 1/tan A

⇒ [2/(cot A - tan A)]

⇒ [2/{(1/tan A) - tan A}]

⇒ [2tan A/(1 - tan² A)] = tan 2A

∴ Its simplified value is tan 2A

After discount, selling price of machine can be given as

⇒ Selling price = 3840 × (1 - 20/100) = 3840 × 0.8

⇒ Selling price = Rs. 3072

∴ The selling price of machine is Rs. 3072

Let the amount in 3% be x, in 5% be y and then in 8% is (7900 - x - y)

According to the problem statement, Since the interest after 1 year is same

⇒ (x × 3 × 1 )/100 = (y × 5 × 1)/100 = {(7900 - x - y) × 8 × 1}/100

Using first two relations

⇒ 3x = 5y

⇒ y = 3x/5     ----(i)

Solving 1^st and 3^rd equation

⇒ 3x = 63200 – 8x – 8y Using (i)

⇒ 11x = 63200 - 8 × (3x/5)

⇒ (79x)/5 = 63200

⇒ x = 4000

∴ The money invested in 3% is Rs. 4000

Given:

x3 - y3 = 81 and x - y = 3

Formula Used:

x³ - y³ = (x - y)(x² + y² + xy)

⇒ (x - y)(x² - 2xy + y² + 3xy)

⇒ (x - y) × {(x - y)² + 3xy}

And, (a - b)² = a² - 2ab + b²

Calculation:

Put the given values in the above equation get,

81 = 3 × (3² + 3xy)

⇒ 27 = 9 + 3xy

⇒ 3xy = 18

⇒ xy = 6      ----(1)

Given x - y = 3, squaring both side

(x - y)² = 3²

⇒ x² + y² – 2xy = 9

⇒ x² + y² - (2 × 6) = 9    [Using (1)]

⇒ x2 + y² = 9 + 12 = 21

∴ The required value of x² + y² is 21

Put cosec A = 1/sin A

⇒ √[{(1/sin A) - 1}/{(1/sin A) + 1}]

⇒ √[{1 - sin A}/{1 + sin A}] Now rationalize

⇒ √[{1 - sin A}²/{1 - sin² A}] Since we know that 1 - sin² A = cos² A

⇒ √[{1 - sin A}²/cos² A]

⇒ (1 - sin A)/cos A

⇒ sec A – tan A

∴ the simplified value of the given expression is sec A - tan A

2x + 1/2x = 2 is only possible when 2x = 1

⇒ 2x = 1

⇒ x = ½

Put this in the required equation

⇒ √[2 × {1/(1/2)}⁴ + {1/(1/2)}⁵]

⇒ √(2 × 2⁴ + 2⁵) 

⇒ √(32 + 32) 

⇒ √64

⇒ 8

∴ Value of required expression is 8

Percentage increase can be given as:

⇒ (5 - 4.5) × 100/4.5

⇒ 0.5 × 100/4.5

⇒ 11.11%

∴ The % increase in sales is 11.11%

Total number of mobile phone sold in 2014 can be given as

⇒ 4 + 4.5 + 6 + 7.5 = 22

⇒ Average sale = 22/4 = 5.5

Now brand 3 and 4 will get stars

Total sale of 2015 = 5.5 + 5 + 6.5 + 8.5 = 25.5

⇒ Average sale = 25.5/4 = 6.375

Brand 3 and 4 will only get stars

Total sale in 2016 = 7.5 + 6 + 7.5 + 9.5 = 30.5

⇒ Average sale = 30.5/4 = 7.625

Only brand 4 will get stars

∴ we can see that brand 4 is having maximum number of stars

Let the age of Ram, Rahim and Ramesh be p, q and r respectively

Given that the average age of Ram and Rahim is 18 years, it can be written as

⇒ (p + q)/2 = 18

⇒ p + q = 36     ----(i)

Given that the average age of Rahim and Ramesh is 25 years, it can be written as

⇒ (q + r)/2 = 25

⇒ q + r = 50     ----(ii)

Given that the average age of Ram and Ramesh is 29 years, it can be written as

⇒ (p + r)/2 = 29

⇒ p + r = 58     ----(iii)

(iii) - (ii)

⇒ p - q = 8     ----(iv)

(i) + (iv)

⇒ 2p = 44

⇒ p = 22 Use this in (iv)

⇒ 22 - q = 8

⇒ q = 14 Put this in (ii)

⇒ 14 + r = 50

⇒ r = 36

∴ The age of eldest one is 36 years

Since we know that this is possible when x = 1

⇒ value of x²¹ + (1/x¹³³¹) = 1 + 1 = 2

∴ The value of x²¹ + (1/x¹³³¹) is 2
