Given statements: H ≥ Z > A, M = A < C, T ≥ L > H

On combining: H ≥ Z > A < C, T ≥ L > H ≥ Z > A = M

Conclusions:

I. T > Z → True (as T ≥ L > H ≥ Z → T > Z)

II. H > M → True (as H ≥ Z > A = M → H > M)

Therefore, both I and II are true.

Given statements: U = E > N, Y ≤ Z < C, U > Y = S

On combining: N < E = U > Y = S ≤ Z < C

Conclusions:

I. Y > N → False (as N < E = U > Y → cannot determine clear relation between Y and N)

II. E > S → True (as E = U > Y = S)

Therefore, only conclusion II is true.

Given statement: B > D < T ≥ V = M ≥ X > Z

Conclusions:

I. T > X → True(As T ≥ V = M ≥ X → T ≥ M ≥ X → T ≥ X)

II. T = X → True (As T ≥ V = M ≥ X → T ≥ M ≥ X → T ≥ X)

Note: Conclusion I and II forms a complimentary pair.

Hence, Either I or II is true.

Given: U < B, B ≥ K, K = M, M ≤ H

On combining: U < B; B ≥ K = M; K = M ≤ H

Conclusions:

I.K ≤ U → False (as, no relation can be established between K and U)

II. H ≥ K → True (as K = M ≤ H)

Hence, only conclusion II follows.

Given statement: M ≤ N ˂ P = R ≥ T ≥ V

I. M ˂ R → As (M ≤ N ˂ P = R) it is clear that R ˃ M, hence true.

II. P ≥ V → As (P = R ≥ T ≥ V) it is clear that P ≥ V, hence true.

So, both conclusions I and II follow.

We draw the least possible Venn diagram:

Conclusions:

I. Some Rusk is Fan → It’s possible but not definite. Hence, false.

II. Some Namkeen is Biscuit → It’s possible but not definite. Hence, false.

Hence, Neither conclusion I nor II follows.

The least possible diagram of this question is as follows,

I. Some nests are definitely exercises → False (it is possible but not definite)

II. All exercises can be nest → True (possibility is true)

Hence, only conclusion II follows.

The least possible Venn diagram for the given statements is as follows,

Conclusions:

1. At least some words are alphabet → False (It is possible but not definite)

2. No word is an alphabet → False (It is possible but not definite)

Here, conclusions I and II are the complementary pair.

Hence, either I or II follows.

The least possible Venn diagram for the given statements is as follows,

Conclusions:

I. No purse is handle → False (It is possible but not definite)

II. Some purse are handle → False (It is possible but not definite)

√1227 – √628 = ?

Taking Approximations

⇒ √1225 – √625 = ?

∴ 35 – 25 = 10

150.121 – (25.93 – ?) × 15.96 = 470.04

Taking Approximations

⇒ 150 – (26 – ?) × 16 = 470

⇒ –(26 – ?) × 16 = 470 – 150

⇒ –(26 – ?) × 16 = 320

⇒ –(26 – ?) = 320/16

⇒ –(26 – ?) = 20

⇒ –26 + ? = 20

∴ ? = 46

122 – ? = √785

Taking Approximations

⇒ 12² – ? = √784

⇒ ? = 144 – 28

∴ ? = 116

160.4 × 9.864 – 56.321 = ?

Taking Approximations

160.4 × 9.864 – 56.321 = ?

⇒ 160 × 10 – 56 = ?

⇒ 1600 – 56 = ?

∴ ? = 1544

66.74% of 6090 – 60.75% of 5297 = ?

Taking Approximations

⇒ 67% of 6100 – 61% of 5300 = ?

⇒ 67 × 61 – 61 × 53 = ?

⇒ 61(67 – 53) = ?

⇒ 61(14) = ?

∴ ? = 854 ≈ 850

1474.8 ÷ 19.5 ÷ 4.2 = ?

Taking Approximations

⇒ 1475 ÷ 20 ÷ 4 = ?

∴ 73.75 ÷ 4 = 18.43 ≈ 18

Given total number of people = 12000

No. of people in town A = 35% of 12000 = 4200

No. of people in town B = 20% of 12000 = 2400

No. of people in town C = 30% of 12000 = 3600

No. of people in town D = 15% of 12000 = 1800

No. of females in town A = 4200 – 2800 = 1400

No. of females in town B = 2400 – 800 = 1600

No. of females in town C = 3600 – 1750 = 1850

No. of females in town D = 1800 – 1100 = 700

Total number of males in town B and females in town D = 800 + 700 = 1500

Total number of males in town C and females in town A = 1750 + 1400 = 3150

Difference = 3150 – 1500 = 1650

Average of total number of males = (2800 + 800 + 1750 + 1100)/4 = 6450/4.

Average of total number of females = (1400 + 1600 + 1850 + 700)/4 = 5550/4.

Required sum = 6450/4 + 5550/4 = 12000/4 = 3000

Total number of females in town B and town C = 1600 + 1850 = 3450

Total number of males in town C and town D = 1750 + 1100 = 2850

Required percentage = (3450/2850) × 100 = 121

Number of males of town A, B and C together = 2800 + 800 + 1750 = 5350

Number of females of town B and D together = 1600 + 700 = 2300

Ratio = 5350 : 2300 = 107 : 46

Total number of females = 1400 + 1600 + 1850 + 700 = 5550

Investment → A : B

           2 : 3

Time →           5 : 4

∵ We know that, Profit sharing ratio = Investment × Time

Profit sharing ratio (PSR) = Investment × Time

PSR →             A : B

       2 × 5 : 3 × 4

             5 : 6

Now, required percentage = (6 – 5)/6 × 100 = 16.66%

Let C.P. of A be Rs. X.

Then C.P of B = Rs. (4400 – x)

Given,

Profit of A = Profit of B

x × 15% = (4400 – x) × 18%

⇒ x = 4400 × 6/2400 = Rs. 2400

∴ C.P of B = (4400 – 2400) = Rs. 2000

GIVEN :

The quantity of milk in a mixture is 58 litre and the quantity of water in the mixture is x litre.

3x litre of milk and 2x litre of water is added in the mixture.

The final ratio of milk and water is 4 ∶ 3. 

CALCULATION :

Milk = 58 litre and Water = x litre

Now, New Quantity of milk = (58 + 3x) litre

New Quantity of water = (x + 2x) litre

Again, According to the question

(58 + 3x)/(x + 2x) = 4/3

x = 58

Quantity of milk in the final mixture = 58 + 3x = 58 + 3 × 58 = 232 litre

GIVEN :

When invested at SI

R = 8%

T = 3 years

When invested at CI

R = 20%

T = 2 years

The amount becomes Rs. 864.

ASSUMPTION :

Let the sum invested be Rs. P₁

CALCULATION :

SI = P₁ × 8 × 3/100 = (24/100)*P₁

Now,

It is given that simple interest is invested at 20% for 2 years of compound interest.

Hence, the principal of compound interest is equal to the simple interest of the sum.

⇒ A = P₂(1 + r/100)ⁿ

⇒ 864 = P₂(1 + 20/100)²

⇒ P₂ = 600

⇒ (24/100) P₁ = P₂ = 600 (As mentioned in the question)

⇒ P₁ = 2500

Probability = Favourable Events/Total Events

2 dices are thrown randomly.

No. of total events = 6² = 36

Favourable events that the sum would be 6.

(1,5); (5,1); (2,4); (4,2); (3,3)

No. of favourable events = 5

⇒ Probability = 5/36

∵ The selling price of rice = Rs. 43.2 per kg

∴ The cost price of rice = 43.2 × 100/150 = Rs. 28.8 per kg

⇒ The cost price of 50 kg = 28.8 × 50 = Rs. 1440

According to question

⇒ 24 × 30 + 20 × x = 1440

⇒ x = Rs. 36

Let the age of father be 8x and the age of mother be 7x.

According to question

8x – 7x = 5

⇒ x = 5

∴ Age of father = 8 × 5 = 40 years

∴ Age of son = 1/5 × 40 = 8 years

We know that surface area of the sphere = 4πr²

⇒ 4πr² = 400π

⇒ r = 10 cm

∴ Diameter = 20 cm

Given that the diameter of the sphere is equal to the side of the square

∴ Side of square = 20 cm

∴ Perimeter of the square = 4 × 20 = 80 cm

Given:

The speed of the stream is 1.5 km/h

Let the speed of the boat be x km/h.

The difference of time, when a boat travels 100 km downstream and 80 km downstream is 1 hour.

Formula used:

Time = Distance/Speed

Upstream speed = speed of the boat - speed of the stream  

Downstream speed = speed of the boat + speed of the stream  

Calculation:

According to the question

100/(x + 1.5) – 80/(x + 1.5) = 1

⇒ 20/(x + 1.5) = 1

⇒ x + 1.5 = 20

⇒ x = 18.5 km/h

∴ The speed of the boat in upstream = 18.5 – 1.5 = 17 km/h

Let the speed of the train B be x m/s.

Total distance covered by trains to cross each other = 250 + 350 = 600 m

Relative speed = (x + 20) m/s

We know that, Speed = Distance/Time

⇒ (x + 20) = 600/12

⇒ x = 30 m/s

Let the income of the person be 100x.

The money spent on rent = 100x × 10/100 = 10x

The money spent in house expanses = (100x – 10x) × 30/100 = 27x

Remaining amount = 90x – 27x = 63x

The money spent on medicine = 3/7 × 63x = 27x

According to the question

⇒ 27x = 8100

⇒ x = 300

∴ Total salary = 100x = 300 × 100 = Rs. 30000

Work done by all the pipes in 1 min = (1/60) + (1/30) – (1/45) = 1/20 – 1/45 = 1/36

Total time taken = 36 min

Let, The price of the mobile is Rs. x

45% of one-fourth of 50% of x is

$= \frac{{45}}{{100}} \times \frac{1}{4} \times \frac{{50}}{{100}} \times x$

= 9x/160

According to the question,

9x/160 = 360

⇒ x = 40 × 160

⇒ x = 6400

Shortcut Trick

Ratio of Wednesday to Monday = 8 : 5.

Given 8 units = 160 → 1 unit = 20.

Monday sale = 5 × 20 = 100.

Friday sale = 120% of Monday = 1.2 × 100 = 120.

∴ The correct answer is 120 phones.

Alternate Method

Given: Ratio Mon : Tue : Wed : Thu = 5 : 4 : 8 : 3.

Given: Sale on Wednesday = 160.

⇒ 8 units = 160

⇒ 1 unit = 160 ÷ 8 = 20

⇒ Sale on Monday = 5 units = 5 × 20 = 100

⇒ Sale on Friday = Sale on Monday + 20% of Sale on Monday

⇒ Sale on Friday = 100 + (20 ÷ 100) × 100

⇒ Sale on Friday = 100 + 20 = 120

∴ The correct answer is 120 phones.

Additional Information

Ratio and Proportion

If a : b is given and the value of 'a' is known, then b = (Value of a ÷ a) × b.

Percentage Increase

To increase a value x by k%, use the formula: New Value = x × (100 + k) ÷ 100.

Unitary Method

Calculate the value of a single unit first, then multiply by the required number of units to find any component of the ratio.

Laptop sold by company in the month of March = 42

Laptop sold by company in the month of March = 58

Average laptop sold by company A and B = (42 + 58)/2

= 100/2 = 50

Laptops sold by company A in the month of April = 50

Laptops sold by company A and B in the month of March = 100

Required difference = 100 – 50 = 50

Laptops sold by company C in the month of April = 60

Laptops sold by company D in the month of April = 50

Required Percentage = {(60 – 50)/50} x 100

= (10/50) × 100 = 20%

11, 21, 61, 241, 1207, 7201

Calculation:

The correct option is 4, RQTPS.

The first sentence will be R as it introduces the subject. 

Since R ends with 'has been' only P and Q can grammatically follow it. Following 'has been' with 'rated as one' makes more sense and is grammatically correct than following it with 'growing cities in the'. Hence, the second part will be Q. 

This means that the correct option is either 3 or 4. Since RQ ends with 'as one' it follows grammatically that the next part be T which is 'of the fastest'. This makes the part: Mumbai has been rated as one of the fastest.

Since option 4 is the only one which which has RQT in it, it is the correct one. 

Hence, the statement becomes:

Mumbai has been rated as one of the fastest growing cities in the world at the moment.

The correct option is 4, TQPSR.

Key Points

• The first sentence will be T as it introduces the subject.
• Since T ends with 'has been' only Q and S can grammatically follow it.

• This means that the correct option is 4 as it is the only one which which has TQP in it.

Hence, the statement becomes: The internet has been likened to a revolutionary introduction almost like the printing press, giving power into the hands of the masses.

The first sentence will be R as it has an introductory tone. 

Since R ends with 'have been' it has to be followed by a noun which is in the part T. Hence, the second part will be T. 

Since option 2 is the only one which has RT in the order, it is the correct one. 

Hence, the statement becomes:

There have been considerable advances in medication but underfunding has continued to keep it limited.

The correct option is 3, ADBCE.

Key Points

• The first sentence will be A as it has an introductory tone.
• Since A ends with the noun 'newsroom' it must follow with a verb which is in part D. Hence, the second part will be D. This means that the correct option is either 1 or 3, as these are the only ones with AD in them.
• C ends with the verb 'lose' and therefore it makes sense grammatically to follow it with a noun which is in E.
• Hence the order of C and E is CE and not EC.
• Therefore, the correct option is 3.

Hence, the statement becomes: The Indian newsroom must be made safe and equal for women or it will lose all credibility.

The correct option is 3, CEADB.

The first sentence will be C as it has an introductory tone. Since C ends with 'not only' which means it should be followed by a verb. Hence, the next part is E.
