Hence, ‘option 3’ is the correct answer.

The logic is:

Heart : Veins → Veins carries blood to heart.

Similarly, Tributaries are freshwater streams that feed into river.

Hence, ‘Tributaries’ is the correct answer.

Logic: Multiplication of first and last term gives the square of middle term

{4, 6, 9} → (4 × 9) = 6²

Similarly,

1. {6, 8, 14} → (6 × 14) = 84 ≠ 8²

2. {9, 15, 18} → (9 × 18) = 162 ≠ 15²

3) {6, 12, 24} → (6 × 24) = 144= 12²

4. {12, 14, 18} → (12 × 18) = 216 ≠ 14²

Hence, ‘{6, 12, 24}’ is the correct answer.

I. Schools are not establishments. → False (As No school is an institution but they are establishment → so, schools are establishment)

II. All schools have buildings. → True (As establishments that are not institutions have buildings and No school is an institution → so, all schools have buildings)

III. Schools do not have buildings. → False (As establishments that are not institutions have buildings and No school is an institution → so, schools do have buildings)

Hence, only conclusion II follows.

Additional Information

• If there are two or more sentences that are used to frame a statement, then, the sentences must be interrelated, and mutual contradiction should be there.
• Do not look for truthful notions. The information provided in the statement is the only requirement for a student to answer the question. No assumptions must be made.
• Read the statement carefully and look for keywords that are common between the statement and the conclusions
• If there is more than one conclusion that is applicable to the statement, students must ensure that the conclusions they opt for have some relation with each other.

The logic is:

1 × 2 + 1 = 3

3 × 2 + 2 = 8

8 × 2 + 3 = 19

19 × 2 + 4 = 42

42 × 2 + 5 = 89 

Hence, ‘89’ is the correct answer.

The pattern followed here is:

According to the alphabetical positions of the letters,

Hence, ‘xebr’ is the correct answer.

1. Six friends A, B, C, D, E and are sitting around a roundtable facing the centre.
2. C is seated between A and B, who is to the immediate left of D.
3. If C is facing E, who is facing F.

The arrangement will be as shown below:

So, ‘B’ is facing F.

Hence, ‘B’ is the correct answer.

The figure from the options which when placed in the blank space of the figure marked ‘X’ would complete the pattern is shown below:

Hence, ‘option C’ is the correct answer.

The figure from the options that would follow next in the given series is shown below:

Filled portion is moving anticlockwise and alternatively skipping one place. Line that dividing the square horizontally and vertically alternatively.

So, the next image in the series will be option 3.

Hence, ‘option C’ is the correct answer.

1. P, Q, R, S, T and U are standing in a queue.
2. Q is just ahead of P.
3. U is NOT near R, who is separated from Q by two persons.

<br>

3. S is just behind T.

In Case II, there is no position left for S and T.

So, it is eliminated.

In case I, III and IV, there is no position left which U can occupy.

So, all the three cases are eliminated.

The final arrangement will be as shown below:

 

So, ‘R’ is standing at the front of the queue.

Hence, ‘R’ is the correct answer.

The logic is:

Hence, ‘54’ is the correct answer.

The pattern followed here is:

According to the alphabetical positions of the letters,

<br>

Words are coded by its reverse letter.

Similarly,

<br>

Hence, ‘UQSO’ is the correct answer.

The option that most closely resembles the mirror image of the given figure is shown below:

Hence, ‘option B’ is the correct answer.

The pattern followed here is:

According to the alphabetical positions of the letters,

1) SOPQ → S – 4 = O; O + 1 = P; P + 1 = Q

2. WTUV → W – 3 = T; T + 1 = U; U + 1 = V

3. HEFG → H – 3 = E; E + 1 = F; F + 1 = G

4. NKLM → N – 3 = K; K + 1 = L; L + 1 = M

Hence, ‘SOPQ’ is the odd one out.

The logic is:

Number of letters in given word + 1 = code in number.

Number of letters in MACE = 4 and 4 + 1 = 5

Number of letters in MASTER = 6 and 6 + 1 = 7

Similarly, Number of letters in SOLUTION = 8 and 8 + 1 = 9

Hence, ‘9’ is the correct answer.

Logic:

1) 5-31 → 5 × 7 + 2 ≠ 31

2. 3-23 → 3 × 7 + 2 = 23

3. 12-86 → 12 × 7 + 2 = 86

4. 8-58 → 8 × 7 + 2 = 58

All except option 1) follow the same logic.

Hence, ‘5-31’ is the odd one out.

1. Pinky is taller than Priya but shorter than Reena.

Reena > Pinky > Priya

2. Riya is taller than Sheela, who is shorter than Priya.

Riya > Sheela and Priya > Sheela

3. Reena is taller than Riya, who is taller than Pinky.

Reena > Riya > Pinky

From all the three statements, we get:

Reena > Riya > Pinky > Priya > Sheela

So, Sheela is the shortest.

Hence, ‘Sheela’ is the correct answer.

The logic is:

1. Rome → Rome is the capital city of Italy.

2. Paris → Paris is the capital city of France.

3. London → London is the capital city of England.

4. Spain → Spain is a European country.

All options except ‘Spain’ are name of cities, while ‘Spain’ is a country.

Hence, ‘Spain’ is the odd one out.

The Venn diagrams that correctly represents the relationships among Women, Mothers, and Engineers is shown below:

The logic followed here is:

1. 33 - composite = 3 × 11
2. 73 - prime number
3. 53 - prime number
4. 23 - prime number

Hence, ‘33’ is the odd one out.

The least possible venn diagram is:

I. All cups are utensils. → True (It is definite, as it is given in statement that all cups are mugs and all mugs are utensil, so all cups will be utensil)

II. Some utensils are cups. → True (It is definite, as it is given in statement that all cups are mugs and all mugs are utensil, then all cups will be utensils and some utensil will definitely be cups)

Hence, both conclusions I and II follow.

1. × and ÷

Given expression: 12 + 18 × 24 ÷ 6 – 3 = 19

After replacing the signs, we get:

L.H.S = 12 + 18 ÷ 24 × 6 – 3

= 12 + 4.5 – 3

= 16.5 – 3

= 13.5 ≠ R.H.S

2) ÷ and +

Given expression: 12 + 18 × 24 ÷ 6 – 3 = 19

After replacing the signs, we get:

L.H.S = 12 ÷ 18 × 24 + 6 – 3

= 16 + 6 – 3

= 22 – 3

= 19 = R.H.S

3. • and ×

Given expression: 12 + 18 × 24 ÷ 6 – 3 = 19

After replacing the signs, we get:

L.H.S = 12 × 18 + 24 ÷ 6 – 3

= 216 + 4 – 3

= 220 – 3

= 217 ≠ R.H.S

4. • and ÷

Given expression: 12 + 18 × 24 ÷ 6 – 3 = 19

After replacing the signs, we get:

L.H.S = 12 + 18 × 24 - 6 ÷ 3

= 12 + 432 – 2

= 444 – 2

= 442 ≠ R.H.S

Hence, ‘÷ and +’ is the correct answer.

GIVEN:

Selling Price = Rs. 882

Discount = 16%

Gain = 20%

FORMULAE USED:

Marked price = Selling Price/(100 - D%/100)

Cost price : Marked price = (100 - discount%) : (100 + profit%)

CALCULATION:

Marked price = 882/[(100 - 16)/100)]

Marked Price = Rs. 1050

According to question

New Discount = 0%

Cost price : 1050 = (100 - 0) : (100 + 20)

Cost Price = 1050 × 100/120

Cost Price = 875

CONCEPT:

Follow BODMAS rule to solve this question, as per the order is given below:

CALCULATION:

[0.08 ÷ 1.2 of (3.4 − 2.6) × 0.8 of 3.2] × 9/16 

⇒ [0.08 ÷ 1.2 of 0.8 × 0.8 of 3.2] 

⇒ [0.08 ÷ 0.96 × 2.56] × 9/16

⇒ [(1/12) × 2.56] × 9/16

⇒ [16/75] × 9/16

⇒ 0.12

∴ required value lies between 0.11 and 0.13

Given:

Height of cylinder h = 28 cm

curved surface area = 176 cm²

Formula used:

Right circular cylinder of radius=r and height=h

⇒ Volume = πr²h

⇒ L.S.A = 2πrh

Calculation:

⇒ 176 = 2 × 3.14 × r × 28

⇒ r = 176/(2 × 28 × 3.14)

⇒ r = 1 cm

Volume of cylinder = 3.14 × 1 × 1 × 28

⇒ 88 cm3.

$\frac{Acid}{Water}$ = $\frac{[2 \times (\frac{2}{9})] + [5 \times (\frac{4}{9})]}{[2 \times (\frac{7}{9})] + [5 \times (\frac{5}{9})]}$

$\frac{Acid}{Water}$ = $\frac{\frac{4}{9} +\frac{20}{9}}{\frac{14}{9} + \frac{25}{9}}$

$\frac{Acid}{Water}$ = 24/39 = 8 :13

∴ The correct answer is 8 : 13.

GIVEN:

In 1st container, acid : water = 2 ∶ 7

In 2nd container, acid : water = 4 ∶ 5

Ratio of mixture = 2 ∶ 5

CALCULATION:

Let "x" be the acid content of the New mixture

Using the principal of allegation

⇒ [(4/9) - x]/[x - (2/9)] = 2/5

⇒ 4/9 - x = 2x/5 - 4/45

⇒ 7x/5 = 4/9 + 4/45

⇒ 7x/5 = 24/45

⇒ x = 8/21

Ratio of Acid : water in the new mixture = 8 : (21 - 8)

Ratio of Acid : water in the new mixture = 8 ∶ 13

∴ The required ratio is 8 ∶ 13.

Alternate MethodGiven,

Ratio of mixture in container 1 = 2 : 7   (sum = 9)

Ratio of mixture in container 2 = 4 : 5   (sum = 9)

Let they contains 90L mixture in both container initially.

Acid in container 1 = 90 ×  2/9 = 20L

Similarly,

Water in container 1 = 90 ×  7/9 = 70L

Acid in container 2 = 90 ×  4/9 = 40L

Water in container 2 = 90 ×  5/9 = 90L

Now, we have to mix it in the ratio of 2 : 5 mean 

 Means 20% from Container 1 & 50 % of Container 2

So,

Acid from Container 1 = 20% of 20L = 4L

Acid from Container 2 = 50% of 40L = 20L

Total Acid in final Mixture  = 4 + 20 = 24 L

Water from Container 1 = 20% of 70L = 14L

Acid from Container 2 = 50% of 50L = 25L

Total Acid in final Mixture  = 14 + 25 = 39 L

So required ration = 24/39 = 8/13 = 8 :13

Given:

Distance covered by boat in upstream = 16 km

Distance covered by boat in downstream = 36 km

Time = 10 hours

Formula used:

Time = distance/speed

Calculation:

Let the speed of stream be "s" km/h

Let the speed of boat be "b" km/h

Upstream speed = (b – s)km/h

Downstream speed = (b + s)km/h

According to question:

⇒ 36/(b + s) + 16/(b - s) = 10      ----(1)

⇒ 3/(b + s) + 1.2/(b - s) = 4/5      ----(2)

Solving equation (1) and (2) simultaneously, we get

s = 1 km/hr, and b = 5 km/hr

∴ Upstream speed = (5 – 1)km/hr = 4 km/hr

Shortcut Trick

According to question:

⇒ 36/(b + s) + 16/(b - s) = 10      ----(1)

⇒ 3/(b + s) + 1.2/(b - s) = 4/5      ----(2)

We take the direct option 4

b - s = 4 km/hr 

Put b - s = 4 kmph in the equation 1 

36/(b + s) + 16/4 = 10

⇒ 36/(b + s) + 4 = 10

⇒ b + s = 6 km/hr

Verify the second equation, Put b - s and b + s in equation 2

⇒ 3/6 + 1.2/4 = 4/5

⇒ 1/2 + 3/10 = 4/5

⇒ 8/10 = 4/5

⇒ 4/5 = 4/5 

∴ Option 4 is the correct answer

FORMULAE USED:

Mean = (Range + mode + median)/3

CALCULATION:

Arrange the given series in ascending order

1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5

Mode = 2

Median = (2 + 2)/2 = 2

Range = 5 - 1 = 4

Mean = (2 + 2 + 4)/3 = 8/3

Mean = $2{ 2\over3}$

GIVEN:

 

Profit = 26%

New selling Price = ₹81.60

New Profit = 32%

FORMULAE USED:

Selling price = (cost price)/100 × (100 + profit%)

CALCULATION:

Let the Cost price be "x"

Selling Price = 1.26x

New Cost Price = 0.8x

New Selling Price = 1.26x - 81.60

1.26x - 81.60 = (0.8x)/100 × (100 + 32)

x = 81.60/0.204

x = 400

∴ the original cost price of the watch is ₹400

Alternate MethodLet CP = 100

At 26% profit sells

SP = 100(100 + 26)/100

⇒ 126

If he bought 20% less Than New CP = 100(100 – 20)/100

⇒ 80

Sold for ₹81.60 less, he would have gained 32%.

⇒ 80 × (100 + 32)/100

⇒ New SP = 105.6

Difference of SP = 126 – 105.6 = 20.4

20.4 on 100

⇒ 1 → 100/20.4

⇒ 81.6 → (100/20.4)81.6

∴ CP = Rs. 400

GIVEN:

Time = 5.5 years

Rate = 6% p.a.

SI = ₹ 2541

New Time = 17/3 years

New Rate = 57/7% p.a.

FORMULAE USED:

SI = (P × R × T)/100

CALCULATION:

Principal = 2541 × 100/(5.5 × 6)

Principal(P) = ₹ 7700

Now,

SI = 7700 × (57/7) × (17/3)/100

SI = 3553

Amount = 7700 + 3553 = ₹ 11253

Shortcut Trick

Speed ratio (Original : New) = 100% : 80% = 5 : 4

Since distance is constant, Time ratio is the inverse of speed ratio = 4 : 5

Difference in time ratio = 5 − 4 = 1 unit → 1¼ hours (5/4 hours)

Original time (4 units) = 4 × (5/4) = 5 hours

Original Speed = Total Distance ÷ Original Time = 250 ÷ 5 = 50 km/hr

∴ The correct answer is 50 km/hr.

Alternate Method

Given:

Distance (D) = 250 km

Speed reduction = 20%

Time increase (Δt) = 1¼ hours = 5/4 hours

Calculations:

⇒ Let original speed be S km/hr.

⇒ New speed = S − 20% of S = 0.8S km/hr.

⇒ Time taken initially (t₁) = 250/S

⇒ Time taken later (t₂) = 250/0.8S

⇒ t₂ − t₁ = 5/4

⇒ 250/0.8S − 250/S = 5/4

⇒ (250 × 1.25)/S − 250/S = 5/4

⇒ 312.5/S − 250/S = 5/4

⇒ 62.5/S = 5/4

⇒ S = (62.5 × 4) ÷ 5

⇒ S = 250 ÷ 5 = 50 km/hr

∴ The correct answer is 50 km/hr.

Additional Information

Speed-Time Inverse Proportionality

When distance is constant, speed is inversely proportional to time (S₁/S₂ = T₂/T₁).

Average Speed Formula

For the same distance covered at two different speeds x and y, Average Speed = 2xy/(x+y).

Relative Speed

In the same direction, relative speed is (S₁ − S₂); in the opposite direction, it is (S₁ + S₂).

GIVEN:

Number of schools = 5

FORMULAE USED:

average = sum of observations / number of observations

CALCULATION:

Number of Boys in School A = (9/17) × 680 = 360

Number of Boys in School B = (4/9) × 720 = 320

Number of Boys in School C = (5/18) × 540 = 150

Number of Boys in School D = (2/3) × 660 = 440

Number of Boys in School E = (13/25) × 900 = 468

Total number of Boys = 360 + 320 + 150 + 440 + 468 = 1738 

 

Average number of Boys per school = 1738/5 = 347.6

 

Number of Girls in School A = 680 - 360 = 320

Number of Girls in School B = 720 - 320 = 400

Number of Girls in School C = 540 - 150 = 390

Number of Girls in School D = 660 - 440 = 220

Number of Girls in School E = 900 - 468 = 432

 

∴ In 3 schools the number of girls is more than the average number of boys per school.

GIVEN:

Number of Schools = 5

CALCULATION:

Total Number of Girls in B and C = 720 × (5/9) + 540 × (13/18)

                                                     = 400 + 390 = 790

Total Number of Boys in A and D = 680 × (9/17) + 660 × (2/3)

                                                     = 360 + 440 = 800

Required Percentage = (800 - 790) × 100/800

Required Percentage = 1.25%

GIVEN:

Average weight = 75.5 kg 

Weight of new people = 72.6 kg, 74 kg, 73.4 kg and 70 kg 

New Average weight = 75 kg

FORMULA USED:

Total weight = Average weight × Number of persons

CALCULATION:

Let the initial number of People be x

Total weight initially = 75.5x

New total weight = 75.5x + 72.6 + 74 + 73.4 + 70 = 75.5x + 290

According to question

⇒ (75.5x + 290)/(x + 4) = 75

⇒ 75.5x + 290 = 75(x + 4)

⇒ 75.5x + 290 = 75x + 300

⇒ 0.5x = 10

x = 20

∴ The number of persons in the group, initially, was 20

GIVEN:

A sold an article to B at a profit of 25%,

B sold that article to C at a profit of 10%

 C sells that article to D at a loss of 40%.

Cost Price for D = ₹ 46.20

CONCEPT:

Successive selling.

FORMULA USED:

If profit ix x%:

SP = CP × (1 + x/100)

If loss ix x%:

SP = CP × (1 - x/100)

CALCULATION:

Suppose the CP for A be Rs. 100

So,

SP for A and CP for B = 100 × 1.25 = Rs. 125

SP for B and CP for C = 125 × 1.1 = Rs. 137.5

SP for C and CP for D = 137.5 × 0.6 = Rs. 82.5

But

It is given that D bought it for Rs. ₹ 46.20

So,

Value of 1 ratio will be 46.20/82.5 = 0.56

So,

A paid 100 × 0.56 = Rs. 56

A's profit = 0.25x = Rs. 14

B's Profit = 0.125x = Rs. 7

∴ The difference between the profits of A and B = 14 - 7 = Rs. 7

GIVEN:

Sides of triangular field = 18 m, 80 m and 82 m

CONCEPT:

CALCULATION:

s = (18 + 80 + 82)/2 = 90

The area of a triangular field = √[90(90 - 18)(90 - 80)(90 - 82)] = √[90 × 72 × 10 × 8] = 720 m²

According to question,

(√3/4) a2 = 5√3 × 720

a = 120

∴  side of the triangular park = 120 m

Alternate MethodSides of triangular field = 18 m, 80 m, and 82 m

Triplet 18² + 80² = 82²

area of right angle triangle = (1/2)Base × Height

⇒ (1/2)18 × 80

⇒ 720 m²

According to question,

(√3/4) a2 = 5√3 × 720

a = 120

∴  side of the triangular park = 120 m

Sum of 41 numbers = 41 × 63 = 2583

Sum of first 21 numbers = 61.5 × 21 = 1291.5 

Sum of last 21 numbers = 65.5 × 21 = 1375.5

21st number = 1375.5 - 1291.5 = 84

Average of numbers excluding 21st number = (2583 - 84)/40

∴ Average of numbers excluding 21st number is 62.475

GIVEN:

Time taken by pipe A to fill the tank = 12 minutes 

Time taken by pipe B to fill the tank = 15 minutes

Total time taken = 10 minutes

FORMULAE USED:

Total Time taken = 1/(1/A + 1/B - 1/C)

CALCULATION:

10 = 1/(1/12 + 1/15 - 1/C)

(1/12 + 1/15 - 1/C) = 1/10 

1/C = 3/20 - 1/10

1/C = 1/20

C = 20 minutes

 L.C.M of 12, 15 and 10 = 60 = Total work

Efficiency of pipe A = 60/12 =5 units/minute

Efficiency of pipe B = 60/15 = 4 units/minute

Efficiency of pipe (A + B + C) = 60/10 = 6 units/minute

Efficiency of pipe C = 6 – (5 + 4) units/minute

Efficiency of pipe C = -3 units/minute

Here negative sign means tank is emptying

So, Time taken by pipe C to empty the tank = 60/3 minutes

⇒ 20 minutes

∴ Time taken by pipe C to empty the tank is 20 minutes

$\frac{\frac{4}{3} + \frac{33}{2} - {\frac{55}{6}}}{\frac{25}{24} × \frac{24}{5}} =\frac{52}{6\times5}=1\frac{11}{15}$

According to question,

Time taken by A to complete the work = x/5

Time taken by B to complete the work = x/6

Time taken by C to complete the work C = x/9

Thus, A, B and C can complete a work in 36 days.

(1/x/5) + (1/x/5) + (1/x/5) = 1/36

(5/x) + (6/x) + (9/x) = 1/36

x = 20 × 36 = 720

∴ Time Taken by B alone will be 120 days

Alternate solution

Let work done per day by A, B and C be 5 units, 6 units and 9 units respectively.

Total work = (5 + 6 + 9) × 36 = 20 × 36 = 720 units

∴ Required time taken by B = 720/6 = 120 days.
