Hence, option 4 is the correct answer.

LOGIC: (First Number)³ + 2 = Second Number

1) In 11 : 1333 →

11³ + 2

= 1331 + 2

= 1333

2) In 9 : 731 →

9³ + 2

= 729 + 2

= 731

3) In 13 : 2197 →

13³ + 2

= 2197 + 2

= 2199 ≠ 2197

4) In 7 : 345 →

7³ + 2

= 343 + 2

= 345

Hence, "13 : 2197" is the correct answer.

Teachers who are Japanese but not Singer are represented by "4".

The ratio of the present ages of Sandhya and Vindhya = 1 : 3

Let;

Age of Sandhya = P

Age of Vindhya = 3P

3 years ago:

Age of Sandhya 3 years ago = (P - 3) years

Age of Vindhya 3 years ago = (3P - 3) years

According to the question:

The ratio of the ages of Sandhya and Vindhya 3 years ago = 1 : 4

(P - 3) : (3P - 3) = 1 : 4

4 × (P - 3) = 1 × (3P - 3)

4P - 12 = 3P - 3

4P - 3P = - 3 + 12

P = 9

So, Age of Sandhya = 9 years

Age of Vindhya = 3 × 9 = 27 years

Age of Sandhya after 3 years = (9 + 3) = 12 years

Age of Vindhya after 3 years = (27 + 3) = 30 years

The ratio of their ages after 3 years = 12 : 30 

= 2 : 5

Hence, "2 : 5" is the correct answer.

Checking each option one by one:

1) In option 1 →

The figure i.e Square is divided into two parts. One part is shaded and one part is blank.

2) In option 2 →

The shaded region is not the half part of the pentagon given.

3) In option 3 →

The figure i.e circle is divided into two parts. One part is shaded and one part is blank.

4) In option 4 →

The figure i.e triangle is divided into two parts. One part is shaded and one part is blank.

Hence, option (2) is the correct answer.

The logic followed is:

Decoding the information, 

 

Given the equation: 10 when 16 want 20 you 5 come 9 = ?

After replacing the signs from left to right and using the BODMAS rule,

10 × 16 + 20 ÷ 5 - 9

= 10 × 16 + 4 - 9

= 160 + 4 - 9

= 164 - 9

= 155

Hence, the correct answer is "155"

According to the English alphabet series and its positional value:

The cost of Cherry = 6 Rs.

The cost of Grape = 10 Rs

Let; number of cherry = x

And; the number of grape = y

According to the question:

(Price of Cherry × Total number of Cherry) + (Price of Grape × Total number of Grape) = Total price

(6 × x) + (10 × y) = 40

6x + 10y = 40 ------(1)

Now; Checking each option one by one and put the value of x in equation (1)

1) Option 1:

If the number of cherry = 5

(6 × 5) + 10y = 40

30 + 10y = 40

10y = 10

y = 1

Number of grape i.e y = 1 (Integer)

2) Option 2:

If the number of cherry = 8

(6 × 8) + 10y = 40

48 + 10y = 40

10y = - 8

y = - 8/10 = - 0.8

Number of grape i.e y = - 0.8 (Not possible)

3) Option 3:

If the number of cherry = 2

(6 × 2) + 10y = 40

12 + 10y = 40

10y = 28

y = 28/10 = 2.8

Number of grape i.e y = 2.8 (Not possible)

4) Option 4:

If the number of cherry = 4

(6 × 4) + 10y = 40

24 + 10y = 40

10y = 16

y = 16/10 = 1.6

Number of grape i.e y = 1.6 (Not possible)

Hence, option (1) is the correct answer.

CONCEPT:

Let us suppose a be the first term and d be the common difference of an AP. Then the nth term of an AP is given by: an = a + (n - 1) × d

CALCULATION:

Given: 2, 11, 20, 29, _______ is an AP 

Here, a = 2 and d = 11 - 2 = 9

As we know that, if a is the first term and d is the common difference of an AP then an = a + (n - 1) × d

Here, we have to find the 15th term i.e n = 15

⇒ a₁₅ = a + 14 d

Substitute a = 2 and d = 9 in the above equation, we get

⇒ a₁₅ = 2 + 126

⇒ a15 = 128

Hence, correct option is 1.

The most vital organ for survival are:

Humans have five vital organs that are essential for survival. These are the brain, heart, kidneys, liver, and lungs.

The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones. It is responsible for our thoughts, feelings, memory storage, and general perception of the world.

The human heart is responsible for pumping blood throughout our body.

The job of the kidneys is to remove waste and extra fluid from the blood. The kidneys take urea out of the blood and combine it with water and other substances to make urine.

The liver has many functions, including detoxifying harmful chemicals, breakdown of drugs, filtering of blood, secretion of bile, and production of blood-clotting proteins.

The lungs are responsible for removing oxygen from the air we breathe and transferring it to our blood where it can be sent to our cells. The lungs also remove carbon dioxide, which we exhale.

Formula used:

Dividend = Divisor × Quotient + Remainder

Calculation:

According to the question,

When a number is divided by 9, the remainder is 6,

Then number will be in form of 9p + 6, where p is quotient

when this number is divided by 21, the remainder is 12

Number = 21q + 12

Putting the value of p such that it gives numbers in three digits,

When p = 11

⇒ 9 × 11 + 6 = 105

When, p = 12

⇒ 9 × 12 + 6 = 114

The numbers will be,

105, 114, 123, 132, 141, 150, 159, 168, 177...

Similarly, Putting the value of q such that it gives numbers in three digits,

When q = 5

⇒ 21 × 5 + 12 = 117

When, q = 6

⇒ 21 × 6 + 12 = 138

When, q = 7

⇒ 21 × 7 + 12 = 159

We get 159 common in both cases and it is the least number in both case,

x = 159 = 1 + 5 + 9 = 15

∴ The sum of the digits of x is 15.

Given:

Principal = Rs. 51,200

Rate = $3\dfrac{3}{4}\%$ = 15/4 %

Time = $2\dfrac{1}{3}$ years 

Formula Used:

Amount = P(1 + R/100)n 

Where P = principal 

A = P + CI

R = rate 

n = time 

Calculation:

Amount = P(1 + R/100)n 

⇒ 51200(1 + 15/400)^{$2\dfrac{1}{3}$}

⇒ 51200(1 + 15/400)² × (1 + 15 × 1/3/400)

⇒ 51200(1 + 15/400)2 × (1 + 5/400)

⇒ 51200[ (1 + 3/80)²(1 + 1/80)]

⇒ 51200(83/80)²(81/80)

⇒ 51200 × 83/80 × 83/80 × 81/80 = (83 × 83 × 81)/10 = Rs. 558,00.9

Compound interest = 55800.9 - 51200 = 4600.9 (approximate to one rupee = Rs. 4,601)

∴ The compound interest is Rs. 4,601.

Given:

Speed of A to B = 48 km/h

Speed of B to C = 120 km/h

AB : BC = 2 : 3

Formula used:

Time = Distance/Speed

Average speed = Total distance/Total time

Calculation:

Let the distance of A to B be 2x km

And the distance of B to BC be 3x km

According to the Question,

Time taken by Abhi, A to B = 2x/48 = x/24

Time taken by Abhi, B to C = 3x/120 = x/40

Total time = x/24 + x/40

⇒ (5x + 3x)/120 = 8x/120

Now, 

Average speed = (2x + 3x)/8x/120

⇒ 5x/8x × 120

⇒ 75 km/h

∴  The average speed for the whole journey is 75 km/h.

Given:

Two numbers are such that their mean proportional = 9

Third proportional = 243

Average = (Sum of observation)/(No. of observation)

Calculation:

Let, the two numbers be x and y respectively,

Mean proportional between x and y = 9

⇒ x : 9 = 9 : y

⇒ xy = 81

⇒ x = 81/y      ----(1)

Third proportional to x and y = 243

⇒ x : y = y : 243

From equation(1), 

⇒ y2 = (243) × (81/y)

⇒ y3 = 243 × 81

⇒ y3 = 27 × 27 × 27 = (27)3

⇒ y = 27

Again, From equation(1), we get,

x = 81/y = 81/27 = 3

Now,

Average = (27 + 3)/2 = 15

∴ The average of those numbers is 15.

Concept : 

Divide the power with 4 if the remainder comes then substitute it as the power of a number placed at the unit place of the number given in the bracket.

Rule of Cyclicity

2, 3, 7 and 8: These numbers follow a cycle of 4 different numbers.

21 = 2, 22 = 4, 23 = 8 and 24 = 16

After that it starts repeating.

So, cycle of 2 has 4 different unit places 2, 4, 8, 6.

31 = 3, 32 = 9, 33 = 27 and 34 = 81

After that it starts repeating.

So, cycle of 3 has 4 different numbers 3, 9, 7, 1.

71 = 7, 72 = 49, 73 = 343 and 74 = 2401

So, cycle of 7 has 4 different unit places 7, 9, 3, 1.

81 = 8, 82 = 64, 83 = 512 and 84 = 4096

So, cycle of 7 has 4 different unit places 8, 4, 2, 6.

Unit digit of 4

4odd = 4, 4even = 6 

Unit digit of 9

9odd = 9, 9even = 1

Unit digit of 6 is 6

Unit digit of 5 is 5 

Calculation:

x = 1 + 22 + 33 + 44 + _ _ _ _ _ + 1010

According to the concept,

⇒ 1 + 4 + 7 + 6 + 5 + 6 + 3 + 6 + 9 + 0

⇒ 47

Unit digit = 7

∴ The unit digit of x is 7.

Calculation:

H.C.F. = 15

Let the number be 15x and 15y

15x + 15y = 150

x + y= 10

Since x and y, should be co - prime because their H.C.F is already given as 15

x + y = 10, if x and y co-prime then

x or y = 7 and. x or y = 3

Take x = 7 and y = 3

Two numbers = 15x = 15 × 7 = 105

⇒ 15y = 15 × 3 = 45

According to the question,

1/15x + 1/15y 

⇒ 1/105 + 1/45

⇒ (3 + 7)/315

⇒ 10/315 = 2/63

∴ The sum of their reciprocals is 2/63.

Given:

Selling price = Rs. 1800

Discount = 20%

Profit % = 20%

Repair charge = Rs. 500

Formula used:

C.P = (S.P × 100)/(100 + profit%)

M.P = [C.P × 100/(100 - Discount%)]

Where, S.P = Selling Price

C.P = Cost Price

M.P = Marked Price

Calculation:

According to the question,

C.P = (S.P × 100)/(100 + profit%)

⇒ C.P = (1800 × 100)/(100 + 20%)

⇒ C.P = 1800 × 100/120 = Rs. 1500

He spends Rs. 500 on its repair,

⇒ C.P = 1500 - 500 = Rs. 1000

M.P = [C.P × 100/(100 - Discount%)]

⇒ M.P = 1000 × 100/80 = Rs. 1250

∴ The marked price of the article is Rs. 1,250.

Calculation:

Let the total students be x

According to the question,

the number of girls is 20% of the total number of students in the class,

⇒ x × 20/100 = 30

⇒ 150

Total no. of boys = 150 - 30 = 120

30 girls in the class out of which 40% get scholarship,

30 × 40/100 = 12

In a class, 40% students get scholarship,

⇒ 150 × 40/100 = 60

Total girls who get scholarship = 12

Total boys who get scholarship = 60 - 12 = 48

The boys do not get the scholarship = 120 - 48 = 72

Required % = 72/120  × 100 = 60%

∴ 60% percent of the boys do not get the scholarship.

Given:

Working 4 hours a day, 50 men can do a piece of work in 21 days.

Formula used:

M₁D₁H₁/W₁ = M₂D₂H₂/W₂

Where,

M₁ = Men₁ , D₁ = Days₁ 

M₂ = Men₂ , D₂ = Days₂ 

H₁ = Hour_1, H₂ = Hour₂

W₁ = Work₁ , W₂ = Work₂

Calculation:

According to the question,

M1D1H1/W1 = M2D2H2/W2

⇒ (50 × 21 × 4)/1 = (M₂ × 20 × 7)/5/2

⇒ M₂ = 75

∴ Required man will be 75.

Hint

one and a half times more  = 1 + 1/2 = 3/2

Simple, Work₂ = (2 + 3)/2 = 5/2

Given:

Radius of smallest circle = 9 cm

Radius of largest circle = 15 cm

Formula used:

Area of circle = πR2

Calculations:

According to the question,

Middle circle divides the area of largest and smallest circle in equal parts

Thus,

 π × (r₃)2 - π × (r2)2 = π × (r2)2 - π × (r1)2

 π × (r3)2 + π × (r1)2 = 2×π (r2)2 

(Area of smallest circle + Area of largest circle)/2 = Area of the middle circle.

⇒ [π × (9)² + π × (15)²]/2 = πr22

⇒ (81 + 225)/2 = r22

⇒ 153 = r22

⇒ r2 = √153

∴ The radius of the middle circle is √153 cm.

Given:

A's profit, while selling to B = 20%

B's profit, while selling to C = 20%

C's loss, while selling to D = 40%

Formula Used:

While selling an article at a profit, we have:

SP = [(100 + %profit)/100] × CP

Similarly, while selling an article at a loss, we have:

SP = [(100 – %profit)/100] × CP

Here SP = Selling Price, and CP = Cost Price.

Calculation:

Let the CP for A be Rs.x

After successive selling, the price became Rs. 691.20

So we get:

[(100 + 20)/100] of [(100 + 20)/100] of [(100 - 40)/100] of x = 691.20

⇒ 120/100 × 120/100 × 60/100 × x = 69120/100

⇒ x = 691200/(12 × 12 × 6 × x) = Rs. 800

CP for A = Rs.800

Profit of A = 800 × 20/100 = 160

CP for B = 800 × 120/100 = 960

Profit of B = 960 × 20/100 = 192

⇒ Difference in profit of A and B = 192 - 160 = Rs. 32

∴ The difference in profit of A and B is Rs. 32.

Formula used: 

A = P(1 + r/100)n

where, A = Amount, P = Principal, r = Rate of interest, n = Time 

Calculation:

Let Anita lent an amount of be Rs. x

Then, Monu lent an amount of Rs. (841,00 - x)

According to the question,

x(1 + 5/100)³ = (841,00 - x)(1 + 5/100)5

⇒ x = (841,00 - x)(21/20)²

⇒ x = (841,00 - x) × 441/400

⇒ 400x = 84100 × 441 - 441x

⇒ 841x = (84100 × 441)/84100

⇒ x = 44100

Anita lent an amount = Rs. 44100

Monu lent an amount = Rs. (841,00 - 44100) = Rs. 40000

Required difference = Rs. 44100 - Rs. 40000 = Rs. 4100

∴ The difference between the amounts lent by Anita and Monu is Rs. 4,100.

Given:

Radius of metallic sphere (R) = 10.5 cm

Radius of circular base of smaller cone (r) = 3.5 cm

Hight of cone (h) = 3 cm

Formula used:

The volume of a sphere = (4/3)πR3,

The volume of cone = (1/3) × πr2h

here, r = radius and h = height

Calculation:

According to the question,

Volume of metallic sphere (V) = (4/3)πR3

⇒ V = 4/3 × 22/7 × (10.5)³

The volume of cone = (1/3) × πr2h

⇒ V = 1/3 × 22/7 × (3.5)² × 3

Number of cones formed (n) = Volume of Sphere/Volume of Cone

⇒ n = [4/3 × 22/7 × (10.5)3]/[1/3 × 22/7 × (3.5)2 × 3]

⇒ n = 4851/38.5 = 126​

∴ The number of cones will be 126.

Given:

Total Strength = 180

Boys = 60%

The average score of all the students in a maths test = 62

Formula Used:

Average = (sum of observations)/ Total number of observations.

Calculations:

Boys = 60% = 180 x 60/100 = 108

Girls = 180 - 108 = 72

Let avgerage of Boys be 5x

Then avgerage score of girls = 5x(100 + 60)/100 

⇒ 5x × 160/100 = 8x

Sum score of all the students in a maths test = 180 ×  62 = 11160 

Sum of boys = 108 ×  5x = 540x

Sum of girls = 72 × 8x = 576x

According to the question,

540x + 576x = 11160

⇒ 1116x=11160

⇒ x = 10

Average of girls= 8x = 8 x 10 = 80

∴ The average score of the girls is 80.

Given:

A person walks 20 km/h slower than his usual speed, he takes 4 hours more to cover a certain distance

He walks 40 km/hr faster than his usual speed, he takes 4 hours less to cover that distance.

Formula used:

Time = Distance/Speed

Speed = Distance/Time

Calculation:

Let the original speed be m km/h and the distance is x km

For the first case get,

x/(m - 20) - x/m = 4  

⇒ x[(m - m + 20)]/m(m - 20) = 4

⇒ x = m(m - 20)/5      ----(1)

Again from the 2nd case get,

x/m - x/(m + 40) = 4 

⇒ x(m + 40 - m)/m(m + 40) = 4

⇒ 40x/m(m + 40) = 4

⇒ x = m(m + 40)/10      ----(2)

From (1) and (2) get,

m(m - 20)/5 = m(m + 40)/10

⇒ 5m + 200m = 10m - 200

⇒ -5m = -400

⇒ m = 80

Original speed = 80 km/hr

Now, from equation(1),

x/(m - 20) - x/m = 4  

⇒ x/(80 - 20) - x/80 = 4  

⇒ x/60 - x/80 = 4

⇒ (4x - 3x)/240 = 4

⇒ x/240 = 4

⇒ x = 960

∴ The distance (in km) is 960.

Calculation:

Let the number be 100

According to the question,

then correct Increased number = 100 x (100 + 25%)/100

⇒ 125

But by mistake he first decreased the number by 25%

⇒ 100 × (100 - 25%)/100 = 75

Then he Increased the result by 25%

⇒ 75 × (100 + 25)/100 = 375/4 = 93.75

Difference between original and new number = 125 - 93.75

⇒ 31.25

Required change % = (31.25/125) × 100 = 25%

∴ Required change % is 25%.

Given:

The ratio of spirit and water in three vessels A, B and C are 1 : 5, 3 : 5, and 5 : 7 respectively.

Calculation:

According to the question,

In vessels A,

Spirit = 2 × 1/6 = 1/3

Water = 2 × 5/6 = 5/3

In vessels B,

Spirit = 3 × 3/8 = 9/8

Water = 3 × 5/8 = 15/8

In vessels C,

Spirit = 4 × 5/12 = 5/3

Water = 4 × 7/12 = 7/3

Total spirit = 1/3 + 9/8 + 5/3 = 25/8

Total water = 5/3 + 15/8 + 7/3 = 47/8

Ratio (in final solution) = S : W= 25/8 : 47/8 = 25 : 47

∴ The ratio of spirit and water in the final solution is 25 : 47.

Given:

Total number of cars manufactured in January and February = 3200

Calculation:

The total number of cars manufactured by all the companies in January = 175 + 250 + 320 + 270 + 380 + 325 = 1720

January + February = 3200

February = 3200 - 1720 = 1480

Required % = [(1720 - 1480) × 100]/1480

⇒ 16.2%

Given:

 

Calculation:

The number of cars manufactured by companies A = 3200 × 12/100 = 384

The number of cars manufactured by companies C = 3200 × 18/100 = 576

The number of cars manufactured by companies E = 3200 × 20/100 = 640

The total number of cars manufactured by companies A, C and E in two months = 384 + 576 + 640 = 1600

Again, according to the question,

The total number of cars manufactured by all the companies in January = 175 + 250 + 320 + 270 + 380 + 325 = 1720

The total number of cars manufactured by all the companies in January and February = 3200

So, The total number of cars manufactured by all the companies in February = 3200 - 1720 = 1480

The total number of cars manufactured by companies E in two months = 3200 × 20/100 = 640

The total number of cars manufactured by companies E in February months = 640 - 380 = 260

the total number of cars manufactured by companies A, B, C, D and F in February = 1480 - 260 = 1220

Required Ratio = 1600 : 1220 = 80 : 61

∴ The ratio of the total number of cars manufactured by companies A, C and E in two months to the total number of cars manufactured by companies A, B, C, D and F in February is 80 : 61.

The correct answer is The fully grown dragon tree is about twenty feet tall and five feet across.

Key Points

The construction of the sentences is incorrect except option 4. Let's explore all the other options: 

• Option 1: Twenty feet tall the fully grown the dragon tree is about and five feet across. 
• ​The use of 'and' after about makes the sentence grammatically absurd.
• Option 2: Twenty feet tall and five feet across the fully grown dragon tree is about.
• ​The sentence doesn't make any grammatical sense.
• Option 3: Twenty feet tall and five feet across is about the fully grown dragon tree.
• ​The use of 'about' is wrong here. It makes the sentence grammatically incorrect.
• Thus, option 4 is the correct sentence in which the subject is **'**The fully grown dragon tree' and the other part of the sentence describes the subject. It makes proper grammatical sense.

<br>

Correct sentence: The fully grown dragon tree is about twenty feet tall and five feet across.

The correct answer is has increased.

Key Points

• The present perfect tense refers to an action or state that either occurred at an indefinite time in the past or began in the past and continued to the present time.
• In such cases, 'has or have' is followed by the third form of the verb, or the past participle form of the verb.
• The singular subject "number" is used. When a singular subject is used, we need to use the singular form of the auxiliary verb "have," which is "has."
• Therefore, "has increased" is the correct option for this sentence.

Confusion Points

• Option 2: increased:- It is in simple past which represents the action that happened at some specific time in past.

The correct answer is or.

Key Points

• Or is used for showing possibilities or choices.
• Eg: You can pay now or when you come back to pick up the paint.
• The given sentence takes about two choices; living in Anupam Apartments/ having moved from there.
• Thus, the correct fit word for the blank is 'or'.

• Hence, option 1 is the most appropriate answer choice.

The correct answer is ​Growing global trade and online pharmacies.

Key Points

• Refer to the lines: 
• The growing global trade in medicines has also opened door to drugs, vaccines and other medical products that do not meet quality standards and are even toxic at times.
• Online pharmacies that are fast gaining popularity - in the US alone 19 to 26 million people now buy medicines online - also pose a threat, as it makes it easier to push poor quality drugs into even the best regulated markets.
• Thus, it can be concluded that Growing global trade and online pharmacies have aggravated the problem of fake and substandard drugs in the market.
• Hence, option 1 is the most appropriate answer choice.
