Hence, Option (3) is correct.

Additional Information

The logic followed is:

Hence, the correct answer is "HAQGWASH".

Statements:

U > H = G ≥ N; E < N > W ≥ O

Conclusion:

I. G > E → True → According to the statement G ≥ N > E

II. H > N → False → According to the statement U > H = G ≥ N

Hence, Option (2) is correct.

Mistake Points

As from the equation H = G ≥ N.

Mistake points:

There is a difference in (≥, >) both the sign.

When H ≥ N means H is greater or equal to N.

When H > N means H is greater than N.

As in conclusion 2, it is said H = G ≥ N from this we cannot say H is greater than N.

Thus conclusion 2 is false.

For this question,

The relation is given below-

M-26

Logic:

1. Letter - (place value of letter x 2)
2. Gap between two letter is 3.

Solution:

M + 3 = P

P + 3 = S

S + 3 = V

V + 3 = Y

According to the same logic option (1) satisfy this logic. Y-50

Logic: Y - (place value of Y x 2)

Y - 25 × 2

Y - 50

Given:

The ratio of the speed of Truck, Car, and Train = 6 : 7 : 9

Car travel 308 km in = 11 hours

Formula used:

S = D/T 

(Where, D = Distance, S = Speed, and T = Time)

Calculation:

Let be assume the speed of the Truck, Car and Train is 6x, 7x, and 9x respectively

⇒ 7x = 308/11

⇒ 7x = 28

⇒ x = 28/7 = 4

⇒ Speed of the Train = 9x = 9 × 4 = 36 kmph

⇒ Speed of the Truck = 6x = 6 × 4 = 24 kmph

⇒ The average speed of Truck and Train = (36 + 24)/2 = 60/2 = 30 kmph

∴ The required result will be 30 kmph.

Given:

The height of the equilateral triangle = 6 × √3 cm

Formula used:

The height of the equilateral triangle = (√3/2) × a   

The perimeter of the equilateral triangle = 3 × a

(Where a = The side of the equilateral triangle)

The area of the square = a²

The perimeter of the square = 4 × a

Where, a = Side of the square

Calculation:

Let be assume the side of the equilateral triangle is a and side of the square is p

⇒ 6 √3 = (√3/2) × a

⇒ a = 12

⇒ The perimeter of the equilateral triangle = 3 × a = 3 × 12 = 36 cm

⇒ 4p = 36

⇒ p = 36/4 = 9

⇒ The area of the square = 9 × 9 = 81 cm

∴ The required result will be 81 cm.

Given:

The expression = 382 + 60 percent of 1350 – 16 × 28 = ?

Concept:

Calculation:

⇒ 382 + 60 percent of 1350 – 16 × 28

⇒ 382 + (60/100) × 1350 - (16 × 28)

⇒ 382 + (135 × 6) - (16 × 28)

⇒ 382 + 810 - 448

⇒ 1192 - 448

⇒ 744

∴ The required result will be 744.

Given:

Total Population (in Lakh) in city A = 87.6

Rural Population (in Percentage) in city A = 40%

Calculation:

According to the question,

The total rural population (approximately) of city A in the year 2011 = 87.6 × 40/100

⇒ 35.04 in approx 35 lakh.

∴ The total rural population (approximately) of city A in the year 2011 is 35 lakh.

Calculation:

$\sqrt[3]{512}$ - $\sqrt[3]{1000}$ + $\sqrt[3]{729}$

⇒ $\sqrt[3]{8 \times 8 \times 8}$ - $\sqrt[3]{10 \times 10 \times 10}$ + $\sqrt[3]{9 \times 9 \times 9}$

⇒ 8 - 10 + 9

⇒ 17 - 10 = 7

∴ The value of ? is 7.

Given:

The radius of the base of the cylinder is tripled

The volume of the cylinder is more than = 200%

Formula used:

The volume of the cylinder = π × r² × h

Where, r = Radius of the cylinder, h = The height of the cylinder

Calculation:

Let be assume the base radius of the cylinder is R and height is h₁ and h₂

⇒ The volume of the cylinder = π × R² × h₁

⇒ Now, the radius of the cylinder is tripled

⇒ The volume of the cylinder = π × (3R)² × h₂

⇒  π × (3R)2 × h₂ = 3 × (π × R2 × h1)

⇒ h₂ × 9 = 3 × h₁

⇒ h₁/h₂ = 3/1

⇒ The decrease % = {(3 - 1)/3} × 100 = (2/3) × 100 = 66.66% ≈ 66.67%

∴ The required result will be 66.67%.

Given:

Arvind's expenditure in February = 2000 

And saving in February = 3000 

Arvind's expenditure in March = 3000

And saving in March = 2400

Arvind's expenditure in May = 4500

And saving in May =  2500

Concept used:

Income = Expenditure + Saving

Formula used:

The average = (The sum of all items)/(The total number of items)

Calculation:

Arvind's Income in February = 2000 + 3000 = Rs. 5000

Arvind's Income in March = 3000 + 2400 = Rs. 5400

Arvind's Income in May = 4500 + 2500 = Rs. 7000

According to the question,

The average = (5000 + 5400 + 7000)/3 = 17400/3 = 5800

∴ The average of Arvind's income in February, March and May is Rs. 5800.

Given:

The ratio of the present age of the P and Q = 3 : 5

Concept:

If A and B are in the ratio is X : Y then,

A = Xp and B = Yp   Where, p = Constant

Calculation:

Let be assume the present age of P and Q is 3x and 5x respectively

⇒ 5x + 7 = 42

⇒ 5x = 42 - 7 = 35

⇒ x = 35/5 = 7

⇒ The age of P = 3x = 3 × 7 = 21 years

⇒ The age of P after 8 years = 21 + 8 = 29 years

∴ The required result will be 29 years.

Calculation:

According to the option,

$\frac{23}{11}$ = 2.09

$\frac{25}{12}$ = 2.08

$\frac{27}{14}$ = 1.92

Given:

The sum of the larger and smaller number = 120

Formula used:

GM% = (GM/TM) × 100

Where, GM = Gain marks, and TM = Total marks

Calculation:

Let be assume the larger number is L and the smaller number is S

⇒ S × (60/100) = (40/100) × L - 16

⇒ 0.60S = 0.40L - 16

⇒ 4L - 6S = 160 ....... (1)

⇒ L + S = 120 ....... (2)

By solving (1) and (2)

⇒ L = 88 and S = 32

⇒ L - S = 88 - 32 = 56

∴ The required result will be 56.

Given:

The total distance covered by Lokesh = 60 km

The total time = 10 hours

The speed of the bus = 3 km/h

The speed of the car = 7 km/h

Formula used:

S = D/T

Where, S = Speed, D = Distance, and T = Time

Calculation:

Let be assume the Lokesh travelled the distance by Bus is X and Car is (60 - X)

⇒ X/3 + (60 - X)/7 = 10

⇒ 7X + 180 - 3X = 21 × 10

⇒ 4X = 210 - 180

⇒ 4X = 30

⇒ X = 30/4 = 7.5 km

∴ The distance travelled by Bus is 7.5 km.

Given:

The Arun alone can complete the work = 15 days

Formula used:

W = E × T   (Where, W = Work, E = Efficiency and T = Time)

Calculation:

Let be assume Ritesh alone can complete the work in R days

⇒ The efficiency of Arun = 1/15

⇒ The efficiency of Ritesh = 1/R

⇒ Remaining work after 3 days working of Arun = {1 - 3 × (1/15)}

⇒ 1 - 1/5 = 4/5

⇒ The efficiency of Arun and Ritesh = 1/15 + 1/R

⇒ The 4/5 work both can complete = 3 days

⇒ Both can complete the work = 3 × (5/4) = 15/4 days

⇒ 1/15 + 1/R = 4/15

⇒ 1/R = 4/15 - 1/15 = (4 - 1)/15 = 3/15 = 1/5

⇒ Ritesh alone can complete the work = 5 days

∴ The required result will be 5 days.

Given:

The total coin = 1260

He distributes the coin in A, B, and C respectively = 2 : 3 : 4

Concept:

If A and B are in the ratio x : y then 

A = xp  and B = yp    Where p = Constant

Calculation:

Let be assume coin of A, B, and C is 2x, 3x and 4x respectively

⇒ 2x + 3x + 4x = 1260

⇒ 9x = 1260

⇒ x = 1260/9 = 140

⇒ Initialy coins of C = 4x = 140 × 4 = 560

⇒ Now, C get = 560 - 200 = 360

Let be assume after A, B, and C get 2p, 3p and xp respectively

⇒ 2p + 3p + xp = 1260    (Where, xp = 360)

⇒ 5p + 360 = 1260

⇒ 5p = 1260 - 360 = 900

⇒ p = 900/5 = 180 

⇒ xp = 360

⇒ x × 180 = 360

⇒ x = 360/180 = 2

∴ The required result will be 2.

Given:

The money lent for = 3 years

Formula used:

I = (P × R × T)/100

Where, I = Simple interest, P = Principle, R = Rate, and T = Time

Calculation:

Let be assume the initial sum is P and rate is R and time is 3 years

⇒ I₁ = (P × R × 3)/100    ........ (1)

⇒ I₂ = {P × (R + 2) × 3}/100   ......... (2)

From equation (1) and (2)

⇒ 366 = I₂ - I₁

⇒ 366 = {(3PR + 6P) - (3PR)}/100

⇒ 36600 = 3PR + 6P - 3PR

⇒ 36600 = 6P

⇒ P = 36600/6 = 6100

∴ The required result will be 6100.

Given:

Total Population (in Lakh) in city G = 22.2

Rural Population (in Percentage) in city G = 15%

Total Population (in Lakh) in city F = 28.2

Rural Population (in Percentage) in city F = 20%

Calculation:

Rural population of city G in the year 2011 = 22.2 × 15/100 = 3.33 lakh

Rural population of city G in the year 2011 = 28.2 × 20/100 = 5.64 lakh

Required difference = 5.64 lakh - 3.33 lakh = 2.31 lakh.

Given:

Loss on selling an article at (5/6) of his marked price = 10%

Formula used:

L% = {(CP - SP)/CP} × 100

Where, L = Loss, CP = Cost price, and SP = Selling price

Calculation:

Let be assume cost price of the article is X and the market price of the article is Y

⇒ The selling price of the article = {(100 - 10)/100} × X = 9X/10

⇒ The selling price of the article = 5Y/6

⇒ 5Y/6 = 9X/10

⇒ Y = 54X/50

⇒ New, selling price of the article = (54X/50) × (95/100)

⇒  New, selling price of the article = 1.026X

⇒ The required % = {(1.026X - X)/X} × 100

⇒ (0.026X/X) × 100 = 0.026 × 100 = 2.6% (Profit)

∴ Required result will be "2.6% profit".

Given:

The average of 5 consecutive multiples of 7 = 28

Formula used:

Average = (The sum of total item)/(The total number of items)

Calculation:

Let be assume the first multiple of 7 is X

⇒ (7 × X) + {7 × (X + 1)} + {7 × (X + 2)} + {7 × (X + 3)} + {7 × (X + 4)} = 28 × 5

⇒ 7 (X + X + 1 + X + 2 + X + 3 + X + 4) = 140

⇒ 5X + 10 = 140/7

⇒ 5X = 20 - 10 = 10

⇒ X = 2

⇒ The square of the first term = (7 × 2)² = 14² = 196

⇒ The square of the last term = {7 × (X + 4)}² = {7 × (2 + 4)}² = 42² = 1764

⇒ The required average = (196 + 1764)/2 = 1960/2 = 980

∴ The required result will be 980.

Given:

The percentage of students who took electrical = 68%

The percentage of students who took electronics = 47

The number of students who took both = 21

Formula used:

GM% = (GM/TM) × 100

Where, GM = Gain marks, and TM = Total marks

Calculation:

Let be assume the total number of students is X

⇒ The number of students who take admission in electrical = (68/100)X = 0.68X

⇒ The number of students who took admission in electronics = (47/100)X = 0.47X

⇒ The total number of students = 0.68X + 0.47X - 21

⇒ X = 0.68X + 0.47X - 21

⇒ X = 1.15X - 21

⇒ 1.15X - X = 21

⇒ 0.15X = 21

⇒ X = 21/0.15 = 140

∴ The required result will be 140.

Given:

The H.C.F of two number = 17

The sum of the number = 119

Concept:

H.C.F = Highest common factor is the product of the smallest power of each common prime factor in the numbers

Calculation:

Let be assume numbers is a and b

⇒ Some of their number = 119

⇒ a + b = 119

⇒ H.C.F of the numbers is 17 then both number is divisible by 17

⇒ a/17 + b/17 = 119/17

⇒ a/17 + b/17 = 7  then,

⇒ First possible numbers = 102, 17

⇒ Second possible numbers = 85, 34

⇒ Third possible numbers = 68, 51

∴ The required result will be "3".

Given:

A number is divided by 308 then remainder = 60

Calculation:

Let be assume number is X and Y is the multiple of 308

⇒ X = (308 × Y) + 60

⇒ {(308 × Y) + 60}/28 = 308Y/28 + 60/28 

⇒ 308Y is completely divisible by 28 but 60 is not completely divisible by 28 and give remainder 4 

⇒ 308Y/28 + 60/28 = 11Y + 2 × 28 + 4/28

⇒ So, if X is divided by 28 then remainder = 4

∴ The required result will be 4.
