Given:

The present age is 137.5% of 16 years before age.

Also the present age is 60% of 15 years after age.

Calculation:

Let the present age be x

So, age 16 years ago was (x – 16)

And age 15 years hence will be (x + 15)

So according to question,

137.5% of (x – 16) = 60% of (x + 15)

⇒ (11/8) × (x – 16) = (3/5) × (x + 15)

⇒ 11x/8 – 22 = 3x/5 + 9

⇒ 11x/8 – 3x/5 = 31

⇒ (55 – 24)x/40 = 31

⇒ 31x/40 = 31

⇒ x = 40

Here, we use the table given below:

LCM: It is a number which is a multiple of two or more numbers.
Calculation:
When they start together they meet for the first time after LCM of (6, 10, 12, 18, 30 and 40)
We can factorize the numbers:
6 = 2 × 3
10 = 2 × 5
12 = 2 × 2 × 3
18 = 2 × 3 × 3
30 = 2 × 3 × 5
40 = 2 × 2 × 2 × 5
⇒ LCM = 2 × 2 × 2 × 3 × 3 × 5 = 360
∴ They will meet after 360 minutes (6 hours) for the first time

Given:

Madhav received 36000 from a credit union

Calculation:

⇒ Interest = (36000 × 12.5 × 2.5)/100

⇒ Interest = 11,250

⇒ He will repay = 36000 + 11,250 = 47,250

∴ The required result will be 47,250.

According to the given information,
Statement (I): D weighs more than only two people. E weighs more than A but less than B.
So,

Distance = Speed × Time

Speed of motor boat = 20km/h

Let the Speed of river = x km/h

While downstream speed = (x + 20)

Time = 75/(x + 20)

While upstream speed = (20 – x)

Time = 75/(20 – x)

Total time taken = 75/(x + 20) + 75/(20 – x)

75/(x + 20) + 75/(20 – x) = 10

300 = (20 – x)(20 + x)

Logic: We have to eliminate the odd pair of the following:

Option A: Author ∶ Pen

Pen is used by the Author for writing a book.

Option B: Chef ∶ Knife

A Knife is used by Chef for cutting vegetables.

Option C: Doctor ∶ Patient

The Doctor treats the Patient.

Option D: Tailor ∶ Needle

The needle is used by Tailor for stitching the clothes.

As it can be seen that all options are analogous except "Option C".

Hence, the correct answer should be "Option C : Doctor ∶ Patient".

Concept:

• Ampere’s Law: Line integral of the magnetic field B around any closed curve is equal to μ0 times the net current I threading through the area enclosed by the curve i.e.

where I - current flowing
Explanation:

• In a simplified form, Ampere's circuital law states that if the field is directed along the tangent to every point on the perimeter L of a closed curve and its magnitude is constant along the curve, then BL = μoI

where I = the net current enclosed by the closed circuit.

• The closed curve is called the Amperean loop which is a geometrical entity and not a real wire loop.

• According to this law, magnetic fields are related to the electric current produced in them.
• The law specifies the magnetic field that is associated with a given current or vice-versa, provided that the electric field doesn’t change with time.
• It can be applied outside the conductor only.

After unfolding the given paper the figure obtained is as shown below :

Hence, the correct answer is "Option A".

⇒ x ÷ y = 2 ÷ 3

⇒ y/x = 3/2

Squaring both sides

⇒ y²/x² = 3²/2²

⇒ y² ÷ x² = 9/4

The correct answer is 6 Ω.

Key Points

We can use Ohm's law to calculate the resistance of the bulb:

Ohm's law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points, and inversely proportional to the resistance (R) between them:

I = V / R

R = V / I

Where:
R = resistance in ohms (Ω)
V = voltage in volts (V)
I = current in amperes (A)

Given that the voltage (V) is 18 V and the current (I) is 3 A, we can substitute these values into the equation to find the resistance (R):

R = V / I

⇒ 18 V / 3 A = 6 Ω

Therefore, the resistance of the bulb is 6 ohms (Ω).

The correct answer is Narmada.
Key Points
Narmada:

• The Narmada River flows through the states of Madhya Pradesh and Gujarat, moving westwards over a length of about 1,312 km before emptying into the Arabian Sea in the Bharuch district of Gujarat.
• This river is considered the traditional boundary between North India and South India, with the Deccan Plateau lying south of it.

Additional Information
Ganga:

• The Ganges or Ganga is one of the longest rivers in India, and it flows through the northern part of the country.
• The Deccan Plateau is not located south of this river; instead, it's geographically much further south.

Krishna:

• The Krishna River is one of the major rivers in India, flowing through the states of Maharashtra, Karnataka, Telangana, and Andhra Pradesh.
• It does flow through the Deccan Plateau, but it's not the river that traditionally marks the northern boundary of the plateau.

Tapi:

• The Tapi River (also known as Tapti) runs in central India between the Godavari and Narmada rivers.
• It flows westwards over a length of 724 km before draining through the Gulf of Khambhat into the Arabian Sea.

Given:

The average of n numbers = m³

The average of m numbers = n³

Formula Used:

Average = Sum of all items / Number of items

Calculation:

Average of n numbers

⇒ m³ = Sum of n numbers/n

⇒ Sum of n numbers = m³ n ………………….. (1)

Average of m numbers

⇒ n³ = Sum of m numbers/m

⇒ Sum of m numbers = n³ m ……………………(2)

From equation (1) and (2)

Average of all numbers = (m³ n + n³ m)/(m + n)

⇒ Average of all numbers = mn (m² + n²)/(m + n)

⇒ Thrice of average of all numbers = 3 × [mn (m² + n²)/(m + n)]

∴ Thrice of average of all numbers is 3mn (m2 + n2)/(m + n)

The correct option is 3 i.e. 3mn (m³ + n³)/(m + n)

The correct answer is fraternity.
Key Points
FRATERNITY, assuring the dignity of the individual and the unity and integrity of the nation:

• It is only when we recognize our interdependence then we are empowered to help build a peaceful nation and a world.
• The citizens need to internalize the principles of equality, justice, and liberty to promote fraternity among all, regardless of religious beliefs, and regional and local diversity.

JUSTICE, social, economic and political:

• Justice ensures that the freedom of one does not become tyranny for another.
• Justice to be truly meaningful needs sharing of power, compassion towards the underprivileged, and empathy towards the disadvantaged.
• An education on rights and duties becomes important to ensure a fight for justice.

LIBERTY of thoughts, expression, belief, faith, and worship:

• Liberty of thought and action is a fundamental value embedded in our Constitution.
• It is the basis for creativity and exploration of new ideas and experiments that can advance social progress.
• Respecting the rights of others to liberty of thought and action is the hallmark of a civilized society.
• Ensuring that this liberty of thought and action is not used to belittle or diminish the beliefs and status of others is what constitutes a decent society.
• Democracy creates an opportunity to pursue one’s chosen ends and respect others’ rights to do so.
• In a diverse country like India, exercising freedom with responsibility is a must for ensuring peace in the nation.

EQUALITY of status and of opportunity; and to promote among them all:

• Equality is another value enshrined in the Constitution.
• Freedom and justice remain mere words if equality is not ensured. It implies freedom from exploitation and ensuring opportunities for an individual’s development, irrespective of background, gender, cultural or socio-economic identity, and status.

[a general rule for these types of questions is the difference in interest value between SI and CI is basically the interest on interest for first year]

Difference in C.I and S.I for 2 years = 1632 – 1600 = Rs. 32

S.I for one Year = PR/100 = half of SI for 2 years = 1600/2 = 800

S.I on RS. 800 for 1 year = 32

⇒ 800 × R/100 = 32

⇒ R = 4%

∴ Difference in CI and SI for 3 years = difference in CI and SI for 2 years × (R/100 + 3)

= 32 × (4/100 + 3) = Rs. 97.28

The logic for this question is mentioned below-

Here, missing term = 2² + 8² + 7²

missing term = 4 + 64 + 49

missing term = 117

Hence, 117 is correct answer.
