The correct answer is Large industrial houses availed licenses to prevent competition.

Key Points

• The industrial licensing system in India had several fallout, including:
• Large industrial houses availed licenses to prevent competition: The licensing system was often manipulated by big business houses to prevent new players from entering the market, thereby limiting competition.
• Most licenses were used up by backward states: The licensing system favored the established industrial centers, and backward states had a tough time getting licenses.
• Most licenses were for importing goods: The licensing system was designed to promote domestic manufacturing, and imports were discouraged.
• Many small private firms appropriated licenses: The licensing system was biased towards large industrial houses, and small private firms had a tough time getting licenses.

Additional Information

• Industrial licensing system:
• The industrial licensing system was introduced in India in 1948 to regulate the growth and development of industries in the country.
• Under this system, the government issued licenses to companies to set up new industries, expand existing ones, or import technology and machinery.
• The licensing system was aimed at achieving a balanced regional development of industries, promoting self-sufficiency, and preventing concentration of economic power in a few hands.
• However, the licensing system was often criticized for being bureaucratic, corrupt, and favoring established players over new entrants.
• The system was gradually dismantled in the 1990s as part of economic liberalization and reforms.

Given:

Marked price = 450,

Discount = 20 %

S.P = 1.5 C.P

Formula used

S.P = (100 - Discount)/100 × M.P

Solution:

Selling price = 450 × (100 - 20) / 100

⇒ 450 × 80 / 100

⇒ 360

According to the question,

Selling price = (3/2) × Cost price.

⇒ 360 =  (3/2) × Cost price.

Cost price = (360× 2) / 3

⇒ 240

Thus, the Cost price of the article is Rs. 240

Given:

Radius of cone (r) = 12 cm

Height of cone (h) = 24 cm

Radius of sphere (R) = 2 cm

Concept:

Spheres are to be made from the metallic cone. Hence, the volume of all the spheres made would be equal to the volume of the metallic cone.

Formula:

Volume of cone = 1/3 × π × r2 × h, where

r = radius of cone

h = height of cone

Volume of sphere = 4/3 × π × R3, where

R = Radius of the sphere

Calculation:

Volume of sphere = 4/3 × π × 2 × 2 × 2 = 32π/3 cm3

Let the total number of spheres cast be "n".

Volume of metallic cone = 1/3 × π × 12 × 12 × 24 = 144 × 8π  cm3

According to the question,

Volume of cone = Volume of one sphere × Total number of spheres cast

⇒ 144 × 8π cm3 = 32π/3 cm3 × n

⇒ n = 36 × 3 = 108

∴ The total number of spheres cast will be 108.

Given

Sin θ = 5/6

Concept used

cot θ = cosθ / sinθ

cos θ = B/H

P2 + B2 = H2

Calculation

Cot θ ⋅ Sin θ  ⋅ Cos θ = cosθ / sinθ × Sin θ × Cos θ

Cot θ ⋅ Sin θ  ⋅ Cos θ = cos²θ

Sin θ = 5/6

52 + B2 = 62

B2 = 36 - 25 = 11

cos2θ = B2/H2

cos2θ = 11/36

∴ The answer is 11/36.

Given:

Discount = 25 %

Discount = 40 %

Profit = 80%

Formula used

S.P = (100 - Discount)/100 × M.P

Calculation

Let the Cost price of the table be 100a

Since he gains a profit of 80%, the selling price = a + (80/100) x a = 180a

Let the Marked price of the table be b

⇒ b – (25/100) x b = 180a

⇒ b = 240a

Now, if he sells the table at 40% discount

New selling price will be = 240a – (240a) x (40/100)

New selling price = 144a

∴ New profit percent = [(144a – 100a)/100a] x 100 = 44%

The answer is 44%

Calculation

The royalty is Rs. 22,500.

15% → 22500

25% → 22500/15 × 25

25% → 37500

The answer is 37500.

Given:

Replaced wine = 75 litres

Number of replacements = 2

The ratio of the wine left in the cask after replacement = 3 ∶ 2

Formula used

Final = Initial(1 - x/c)ⁿ

x = quantity withdrawn

c = quantity withdrawn from

n = No. of times

Calculation:

Since the quantity withdrawn is replaced by an equal amount of water, the final quantity remains the same.

Let the original quantity = 3x + 2x = 5x

3/5 = (1 - 75/5x)(1 - 60/5x)

Using the options:

If we use x = 300

3/5 = (1 - 75/300)(1 - 60/300)

3/5 = 3/5

Hence the cask initially holds 300 L of wine.

Shortcut Trick

Apply the Substitution Method by assuming a standard angle for A.

Let A = 0°, then sin 0° = 0 and cos 0° = 1.

Expression = (1 / (1 + 0)) + ((1 + 0) / 1) + 2 = 1 + 1 + 2 = 4.

Now, check the options for A = 0° where sec 0° = 1:

Option (4): 2(1 + sec 0°) = 2(1 + 1) = 4.

∴ The correct answer is 2(1 + sec A).

Alternate Method

Given: (cos A) / (1 + sin A) + (1 + sin A) / (cos A) + 2

Formula Used: sin² A + cos² A = 1 and sec A = 1 / cos A

Step 1: Simplify the fractional part of the expression by taking the LCM.

⇒ [cos² A + (1 + sin A)²] / [cos A(1 + sin A)] + 2

⇒ [cos² A + (1 + 2 sin A + sin² A)] / [cos A(1 + sin A)] + 2

⇒ [(sin² A + cos² A) + 1 + 2 sin A] / [cos A(1 + sin A)] + 2

Step 2: Using the Pythagorean Identity (sin² A + cos² A = 1):

⇒ [1 + 1 + 2 sin A] / [cos A(1 + sin A)] + 2

⇒ [2 + 2 sin A] / [cos A(1 + sin A)] + 2

⇒ 2(1 + sin A) / [cos A(1 + sin A)] + 2

Step 3: Cancel the common factor (1 + sin A) and convert to secant.

⇒ 2 / cos A + 2

⇒ 2 sec A + 2

⇒ 2(1 + sec A)

∴ The correct answer is 2(1 + sec A).

Additional Information

Fundamental Trigonometric Identities

Basic relations used for simplification include sin² A + cos² A = 1, 1 + tan² A = sec² A, and 1 + cot² A = cosec² A.

Reciprocal Functions

The secant function is the reciprocal of cosine (sec A = 1/cos A), while cosecant is the reciprocal of sine (cosec A = 1/sin A).

Angle Substitution Strategy

For trigonometric expressions, substituting A = 0°, 45°, or 90° (where defined) can help eliminate options quickly without complex algebra.

Given:

When two different number is divided by the same divisor the remainder are 57 and 57 respectively. And when the sum of these two numbers is divided by the same divisor the remainder is 49.

Concept Used:

Dividend = Divisor × Quotient + Remainder

Calculation:

Let the divisor be ‘d’ and the quotient be q₁ for the dividend x, q₂ for the dividend y and q₃ for the dividend (x + y)

∴ By the given condition,

x = q₁ × d + 57

y = q₂ × d + 57

And (x + y) = q₃ × d + 49

Since q₁, q₂, q₃ are whole numbers and in all cases, the remainder are 57, 57 and 49 then it is obvious that the divisor d > 57

∴ (x – 57), (y – 57) and (x + y – 49) all will completely divisible by d      ….(1)

∴ {(x – 57 + (y – 57)} is also completely divisible by d

⇒ (x + y – 114) is also completely divisible by d      ….(2)

Now, from (1) and (2) we can write {(x + y – 49) – (x + y – 114)} = 65, must be divisible by ‘d’ or ‘d’ be a factor of 65

Now, factors of 65 are 1, 5, 13 and 65

Since d > 57, the value of ‘d’ must be 65

∴ The required divisor is 65

Divisor = 1^st remainder + 2^nd remainder – 3^rd remainder

Here 1^st remainder = 57

2^nd remainder = 57

3^rd remainder = 49

∴ Required divisor = 57 + 57 – 49

⇒ 65

Given

Mahima purchased a Saree for Rs. 792 after successive discounts of 20% and 12%.

Formula used

S.P = (100 - discount)/100 × M.P

Calculation

Let the marked price (M.P.) of the article be a

Price after first discount = a – (20/100)a = 0.8a

Price after second discount = 0.8a – (12/100)0.8a = 0.704a

since, the selling price = 0.704a = Rs. 792

⇒ a = 792/0.704 = Rs.1125

The answer is 1125.

Given:

If the curved surface area of a cylinder is increased by 20%, and height is decreased by 4%,

Concept used:

The volume of a cylinder = πr²h

Calculation:

Since curved surface area of a cylinder includes both radiues and height, we can use the successive change formula:

20% = x% - 4%  - (x × 4)/100

24% = 24/25x

x = 25%

Radius is increased by 25%.

Let the initial volume be 400v.

Percentage increase in volume = 400v × 5/4 × 5/4 × 24/25

Increase in volume = 600v - 400v = 200v

Percentage decrease in volume = (200v/400v) × 100 = 50%

∴ The increase in the volume of the cylinder is 50%

a3 + b3 + c3 – 3abc = (a + b + c)( a2 + b2 + c2 – ab – bc – ca)

Calculation

We have,

(a + b + c)² = 5²

a² + b² + c² + 2(ab + bc + ca) = 25

15 + 2(ab + bc + ca) = 25

2(ab + bc + ca) = 10

(ab + bc + ca) = 5

Now,

a³ + b³ + c³ – 3abc = (a + b + c)( a² + b² + c² – ab – bc – ca)

a³ + b³ + c³ – 3abc - 27  = (a + b + c)[a² + b² + c² –(ab + bc + ca)] - 27

a3 + b3 + c3 – 3abc - 27 = 5 × [15 – ( 5 )] - 27
