Given:

A train running at 60 kmph crosses a pole in 30 seconds.

Formula used:

Speed = Distance/Time

Calculation:

As compared with length of the train, length of the pole is negligible

We know that speed = distance/time

Speed = 60 kmph = 60 × (5/18)m/s 

⇒ Length of train = 60 × (5/18) × 30 = 500 m

∴ Length of the train is 500 m

The right answer is Pluto

Key Points

Pluto is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune. It was the first Kuiper belt object to be discovered. Pluto was discovered by Clyde Tombaugh in 1930 and was originally considered to be the ninth planet from the Sun

Additional Information

According to IAU-International Astronomical Union, Pluto lot its eligibility to be a Planet. 

 So, the three criteria of the IAU for a full-sized planet are:

1. It is in orbit around the Sun.
2. It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape).
3. It has “cleared the neighbourhood” around its orbit.

Pluto meets only two of these criteria, losing out on the third. So it is a Dwarf Planet

Biogas is a mixture of different gases, major portion in biogas being methane (CH4) and carbon dioxide (CO2). It also contains traces of other gases like hydrogen (H2), Moisture (H2O) , hydrogen sulphide (H2S)etc. Improved digesters used for anaerobic digestion can produce biogas with 65% - 75% methane content.

15 is the least number required to be added to 3105 so that it is exactly divisible by 3, 4, 5 and 6.

Given

Ratio of milk and water are in the ratio 1 : 3 and 2 : 1.

Calculation

Let volume of each container is 12 lt.

Hence,

In container 1

Volume of milk = 12 × (1/4) = 3 lt

Volume of water = 12 × (3/4) = 9 lt

In container 2

Volume of milk = 12 × (2/3) = 8 lt

Volume of water = 12 × (1/3) = 4 lt

Now,

Total milk = 3 + 8 = 11 lt

Total water = 4 + 9 = 13 lt

∴ Required ratio = 11/13 = 11 : 13

We know that efficiency $\propto {\rm{;}}\frac{1}{{no;of;working;days}}$

Given that efficiency of work P and Q are in the ratio of 5 : 7

∴ Ratio of number of days taken by them to finish the work = 7 : 5

Students who like Physics = (Physics) + (Physics + Geometry) + (Physics + Algebra)

= 8 + 5 + 7 = 20

Student who like physics but not Geometry = students who like physics – (physics + geometry)

= 20 – 5 = 15

Students who like more than one subject,

Algebra + trigonometry = 5

Physics + geometry = 5

Algebra + physics = 7

Total students = 5 + 5 + 7 = 17

Students who like algebra = 12 + 5 + 7 = 24

Students who like geometry = 13 + 5 = 18

Ratio,

Algebra : Geometry

= 24 : 18

= 4 : 3

Shortcut Trick

Difference between first and last number = 3 × (Average of first three − Average of last three)

⇒ First − Last = 3 × (18 − 14) = 12

Given: First + Last = 16

Subtracting both: 2 × Last = 16 − 12 = 4 ⇒ Last = 2

∴ The correct answer is 2.

Alternate Method

Let the four numbers be A, B, C, and D.

Given:

Average of first three numbers (A, B, C) = 18

Average of last three numbers (B, C, D) = 14

Sum of first and last number (A + D) = 16

Formula Used:

Average = Sum of observations ÷ Number of observations

⇒ Sum of observations = Average × Number of observations

Calculations:

⇒ Sum of first three numbers: A + B + C = 18 × 3 = 54 --- (Equation 1)

⇒ Sum of last three numbers: B + C + D = 14 × 3 = 42 --- (Equation 2)

Subtracting Equation 2 from Equation 1:

⇒ (A + B + C) − (B + C + D) = 54 − 42

⇒ A − D = 12 --- (Equation 3)

Given that the sum of the first and last number is 16:

⇒ A + D = 16 --- (Equation 4)

Subtracting Equation 3 from Equation 4:

⇒ (A + D) − (A − D) = 16 − 12

⇒ 2D = 4

⇒ D = 2

∴ The correct answer is 2.

Additional Information

Average of Arithmetic Progression (AP)

For any sequence in AP, the average is the middle term (if the number of terms is odd) or the average of the two middle terms (if even). It is also calculated as (First term + Last term) ÷ 2.

Weighted Average Formula

When two groups of sizes n₁ and n₂ having averages A₁ and A₂ are combined, the weighted average is given by: (n₁ × A₁ + n₂ × A₂) ÷ (n₁ + n₂).

Average Change on New Entry

If a new value is added to a group and the average increases by x, the new value = Old Average + (New Number of Members × x).

Let the elder sister's age be x and younger sister's age be y

Given that difference between two the ages of to sisters is 2 years

⇒ x - y = 2

Given that father's age is 52, then mother's age = 50

Also given that elder sister's age x = half of the mother's age = 50/2 = 25

Substitute x = 25 in x - y = 2

⇒ 25 - y = 2

⇒ y = 25 - 2 = 23

Given:

Amount after 3 years = Rs. 8700

Time = 3 years

Rate of interest = 15%

Formula used:

S.I = PRT/100

Principal = Amount – S.I

Calculation:

P + [(P × 3 × 15)/100] = Rs. 8700

⇒ P + (9P/20) = Rs. 8700

⇒ 29P/20 = Rs. 8700

⇒ P/20 = Rs. 300

⇒ P = Rs. 6000

∴ The principal amount is Rs. 6000

From the given word,

Similarly, for the word ELEANOR,

Hence, the word ELEANOR is DKDAMNQ.

Total amount for 5 dozen small and 10 dozen big note books = (12 × 5 × 10) + (10 × 12 × 15) = Rs. 2400

According to the given data, we make a family tree,

L + M → L is mother of M

M × N → M is maternal aunt of N

Hence, according to the family tree, L is the maternal grandmother of N.

The given equation is of the form:

[(a + b)² ​– (a – b)²] /ab

Where, a = 525, and b = 252

So, we have:

[(a + b)2 ​– (a – b)2] /ab = 4ab/ab = 4

Hence,  we can write the solution as follows:

∴ [(525 + 252)² – (525 – 252)²] / (525 × 252)

= (4 × 525 × 252) / (525 × 252) = 4

From given data,

⇒ cosθ = √3/2

GIVEN:

Number of Five rupee note = Number of Ten rupee note = Number of Twenty rupee note

CALCULATION:

Let the equal number of five, ten and twenty rupee notes be x

⇒ 5x + 10x + 20x = 385

⇒ 35x = 385

⇒ x = 385/35 = 11

Total number of notes = 11 notes of Rs 5 + 11 notes of Rs 10 + 11 Rs of 20 =  33 notes

11 notes of Rs 5 + 11 notes of Rs 10 + 11 Rs of 20 = 11 × 5 + 11 × 10 + 11 × 20 = 55 + 110 + 220 = Rs. 385

Total number of notes = 11 × 3 = 33 

Therefore the correct answer is 33.

Alternate Method

Since the number of Rs 5, Rs 10, and Rs 20 notes are equal, the ratio of the number of notes is = 1 ∶ 1 ∶ 1

Or, we can say, the total number of notes must be multiple of 3.

 Only two options are multiple of 3, others can be eliminated.

option 2: 33. That means the number of notes of each dimension is 33/3 = 11.

5 × 11 + 11 × 10 + 11 × 20 = 385

∴ The total number of notes is 33.

The correct answer is option 1 i.e, A (Ctrl+V).

Given:

We have to find the mean of the first 11 natural number.

Concept Used:

Mean = Sum of all observations / Number of observations

The sum of the first n natural number = n(n + 1)/2

Calculation:

We know that sum of the first n natural numbers = n(n + 1) /2

⇒ Sum of first 11 natural numbers = 11 × (11 + 1)/2 = 66

Mean of the first 11 natural numbers = 66/11

⇒ 6

∴ The mean offirst 11 natural number is 6.

We know that (a - b)³ = a³ - b³ - 3a²b + 3b²a

⇒ (a - 4)³ = a³ - 4³ - 3a² × 4 + 3 × 4² × a

 = a³ - 12a² + 48a - 64

Alternate Method

This type of questions can be solved by putting value of a = constant

Let a = 1, so (1 - 4)3 = -27

By option 4, we have a3 - 12a2 + 48a - 64

⇒ 13 - 43 - 3(1)2 × 4 + 3 × 42 × 1

⇒ -27

Work done by B in 20 days = 50/100 = 1/2

Work done by B in one day = [1/2]/20 = 1/40

Work done by B and C in 4 days = 50/100 = 1/2

Work done by B and C in one day = 1/8

⇒ Work done by C in one day = 1/8 - 1/40 = 4/40 = 1/10

∴ C alone take 10 days to complete the whole work

Key Points

• The Lasoong festival is the most popular festival of Sikkim.
• It is usually celebrated at the end of the tenth Tibetan lunar month (usually December).
• It is the most important festival among the Bhutias in India and is marked by the traditional Chaan dancing and merry-making

From the given data,

CP = cost price

SP = selling price = Rs. 1235

We know that Loss % = (CP - SP)/CP × 100

⇒ 5 = (CP - 1235)/CP × 100

⇒ 100CP - 5CP = 123500

⇒ 95CP = 123500

⇒ CP = 123500/95 = Rs. 1300

∴ Cost price of the article is Rs. 1300

Also given that to find the selling price to get the profit of 10%

We know that profit % = (SP - CP)/CP × 100

⇒ 10 = (SP - 1300)/1300 × 100

⇒ 13000 = 100SP - 130000

⇒ 143000 = 100SP

⇒ SP = 143000/100 = 1430

⇒ Selling price to get a profit of 10% = Rs. 1430

Alternate Method

Let the C.P be 100 

S.P of the article at 5% loss = 100 × 95/100 = 95 

S.P of the article at 10% profit = 100 × 110/100 = 110 

Accoding to the question S.P of the article at 5% loss

So, required S.P = (1235/95) × 110 = 1430

∴ The required S.P is 1430

Given: 22x – 40 = 207 + 3x

⇒ 22x - 40 = 207 + 3x

⇒ 19x = 247

⇒ x = 247/19 = 13

Let the numbers be 4x and 3x, then their HCF = x

Given that HCF = 8

⇒ x = 8

∴ The numbers are 32 and 24

⇒ LCM of 32 and 24 = 2 × 2 × 2 × 4 × 3 = 96

Given:

Selling price (SP) of the article = Rs. 920

CP = cost price

Profit = 15%

Formula used:

We know that profit% = (SP - CP)/CP × 100

Calculation:

15 = (920 - CP)/CP × 100

⇒ 15CP = 92000 - 100CP

⇒ 115CP = 92000

⇒ Cost price = 92000/115 = Rs. 800

Also given that to find selling price to get a profit of 20%

⇒ 20 = (SP - 800)/800 × 100

⇒ 16000 = 100SP - 80000

⇒ 96000 = 100SP

⇒ SP = 96000/100 = Rs. 960

⇒ Selling price of the article to get a profit of 20% is Rs. 960

Shortcut Trick

CP = 920×100/115 = 800 

At profit 20%

⇒ New SP = 800×120/100

⇒ 960

∴ The selling price is Rs. 960.

We know that,

Amount = SI + P

SI = Simple interest

P = principal

R = rate

T = time

⇒ Amount for SI = P × T × R/100 + P

= (5000 × 2 × 5)/100 + 5000 = Rs. 5500

We also amount for compound interest (CI) = P (1 + R/100)ⁿ

Where, n = time

⇒ Amount for CI = 5000 (1 + 5/100)² = Rs. 5512.50

∴ Their difference = 5512.50 - 5500 = Rs. 12.50

We know that area of trapezium = 1/2 × height × (a + b)

Where, a = length of the side parallel to the base

b = base

⇒ 18 sq.cm = 1/2 × 3 × (a + 5)

⇒ 36 = 3a + 15

⇒ 21 = 3a

⇒ a = 21/3 = 7 cm

∴ Length of the side parallel to the base is 7 cm

The correct answer is option 1 i.e., B (18 Zones).

• Indian Railways is divided into 18 zones and 73 divisions.
• A Divisional Railway Manager (DRM) heads the division and he/she reports to the General Manager (GM).

From the given data,

⇒ Fiction books in library GHL - Self-Help books in library GHL = 610 - 170 = 440

Total count of books in ABL = 150 + 500 + 750 + 100 + 175 + 115 = 1790

Total count of books in GHL = 170 + 600 + 610 + 130 + 100 + 100 = 1710

Total count of books in MNL = 200 + 550 + 700 + 100 + 100 + 150 = 1800

Total count of books in PQL = 200 + 600 + 600 + 110 + 75 + 200 = 1785

∴ Total count of books is highest in MNL

From the given data,

Difference between the total number of Non-fiction books and the total number of management books of all four libraries = (500 + 600 + 550 + 600) - (100 + 130 + 100 + 110) = 2250 - 440 = 1810

⇒ (sinθ/cosθ) × (cotθ/cosecθ)

= (sinθ/cosθ) × [(cosθ/sinθ)/(1/sinθ)]

= (sinθ/cosθ) × ((sinθ × cosθ)/sinθ)

= sinθ

According to the statement,

Both Aryabhata and moon are satellites of the earth but the moon is a natural satellite and Aryabhata is an artificial satellite.

Hence, both conclusions do not follow from the statement.

InDIGO or IndIGO or LIGO  is a consortium of Indian gravitational-wave physicists. This is an initiative to set up advanced experimental facilities for a multi-institutional observatory project in gravitational-wave astronomy.

First Statement does not say that all other professions are ethical so we cannot conclude that only medical profession is unethical.

Second statement says all (ethical and unethical) people are afraid of falling sick. So, it does not follow that only unethical person fall sick.

Hence, neither first nor second conclusion follows the statements.

Ban Ki-moon is a South Korean diplomat who was the eighth Secretary-General of the United Nations from January 2007 to December 2016.

Let the time taken by K with l = x hrs and time taken by K with M = y hrs

We know that, speed × time = distance

Given that total distance = 27 km

⇒ 3x + 6y = 27      ----- equation (1)

Also given that total time taken = 7 hrs

⇒ x + y = 7     ---- equation (2)

Subtract equation (1) from 6 × equation (2), we get

⇒ 3x = 15

⇒ x = 15/3 = 5 hrs

Substitute x = 5 in x + y = 7

⇒ y = 2 hrs

∴ K travelled with M = 6y = 6 (2) = 12 km
