Given:

Two conditions are given

Concept Used:

Any number ends with zero should in the form of 2^m × 5ⁿ where both m and n are positive integer

Calculation:

Consider the first statement, (12)ⁿ never ends with zero

∴ (12)ⁿ = (3 × 4)ⁿ = (3)ⁿ × (4)ⁿ so, (12)ⁿ never ends with zero

Now, Consider the second statement, (6)ⁿ is divisible by 5

∴ (6)ⁿ = (3 × 2)ⁿ = (3)ⁿ × (2)ⁿ

∵ (6)ⁿ never ends with zero

∴ (6)ⁿ is not divisible by 5

Hence, option (1) is correct

Correct option is D) somewhere quiet to live

Given:

Sum of numbers = 128

Concept:

Simple addition and in this type of questions how we need to use options to extract Our answers.

Calculation:

In this types of questions check the options
 

Option (1)

Let the numbers be 9x and 7x respectively

⇒ 9x + 7x = 128

⇒ 16x = 128

⇒ x = 8

⇒ 9x = 9 × 8 = 72 and 7x = 7 × 8 = 56
 

Option (2):

Let the numbers be 7x and x respectively

⇒ 7x + 1x = 128

⇒ 8x = 128

⇒ x = 16

⇒ 7x = 7 × 16 = 112 and x = 1 × 16 = 16
 

Option (3):

Let the numbers be 4x and 3x respectively

⇒ 4x + 3x = 128

⇒ 7x = 128

⇒ x = 18.285

⇒ 4x = 4 × 18.285 = 73.1428 and 3x = 3 × 18.285 = 54.8571
 

Option (4):

Let the numbers be 2x and 2x respectively

⇒ 2x + 2x = 128

⇒ 4x = 128

⇒ x = 32

⇒ 2x = 2 × 32 = 64 and 2x = 2 × 32 = 64
 

Option (5):

Let the numbers be 3x and 5x respectively

⇒ 3x + 5x = 128

⇒ 8x = 128

⇒ x = 16

⇒ 3x = 3 × 16 = 48 and x = 5 × 8 = 80

∴ We can say that number 128 cannot be divided in the ratio 3 : 4

Given:

Two statements are given

Concept Used:

Basic of number system

Calculation:

Consider the first statement; the HCF and LCM of two numbers are equal only if the number is equal to each other

∴ The HCF and LCM of numbers cannot be equal to each other

So, statement 1 is correct

Now, Consider the second statement, Remainder is always less than to divisor

According to Euclid’s lemma the reminder is always less than divisor but greater than or equal to zero

∴ Statement 2 is incorrect

Hence, option (1) is correct

Correct option is A) must have dropped

Correct option is C) published

Given:

The given number is x1001y

Concept Used:

Divisibility rule

Calculation:

By the first statement, If the value of x and y is 1 then it is divisible by 11

∴ The number is 110011 which is divisible by 11

So, statement 1 is correct

By the second statement, the divisibility by even number is dependent on Y

∵ The divisibility by even number is checked by the last digit of the number

∴ The Y must be even to divide the whole digit by an even number

So, statement 2 is correct

By the third statement, the divisibility by 3 is dependent on X and Y both

∵ The divisibility by 3 is checked by the sum of all digits

So, statement 3 is correct

Hence, option (4) is correct

Given:

The given digit is 85ab46 and sum of digits a and b is 5

Concept Used:

Divisibility by 11 is check by subtracting the sum of digits of odd places to sum of digits of even places

If the difference is zero or multiple of 11 then the whole number is divisible by 11

Calculation:

It is given that sum of a and b is 5

∴ a + b = 5     ----(1)

Now, according to the concept

Sum of odd place digit = 14 + a

And Sum of even place digit = 11 + b

Now, it is given that the digit is divisible by 11

∴ 14 + a – 11 – b = 0

⇒ a – b = -1      ----(2)

By equation (1) and (2)

∴ a = 2 and b = 3

Now, consider the statements 1, the product of digits is 6

∴ a × b = 2 × 3 = 6

So, statement 1 is correct

Now, consider the statements 2, the digit is 852346

∴ Required number = 85ab46 = 852346

So, statement 2 is correct

Now, consider the statements 3, both digits are not prime number

∴ Both 2 and 3 are prime number

So, statement 3 is incorrect

Hence, option (1) is correct

Given:

The given expressions are X = a²ⁿ – b²ⁿ, Y = (a + b) and Z = (a + b)

Formula used:

Identity: ((a)² – (b)²) = (a + b) × (a - b)

(a^m)ⁿ = a^{m × n}

Calculation:

It is given that X = a²ⁿ – b²ⁿ for any natural value of n X can be factories by using the identity ((a)² – (b)²) = (a + b) × (a – b)

X = (a²ⁿ – b²ⁿ) × (a + b) × (a – b)

Y and Z both are multiple of (a + b) × (a - b)

It is divisible by both Y and Z

Hence, option (3) is correct

Given:

The given expression is A = ((222)² – (111)²)

Formula used/concept Used:

Concept of divisibility

Identity: ((a)² – (b)²) = (a + b) × (a – b)

Calculation:

By using the identity, the given expression can be simplified

∴ A = ((222)² – (111)²) = (222 + 111) × (222 - 111)

⇒ 333 × 111

So, A is divisible by both 3 but not by 11

∴ Statement I is correct.

Given:

The given expression is A = \({128^{{{128}^{128}}}}\)

Concept Used:

Basic simplification and concept of unit digit

Calculation:

The given expression can be written as 128^{128 × 128 × 128………… × 128 times}

Again the expression can be simplified as 128^{128 × (128 × 128 × 128………… × 127 times)}

∴ 128^{128 × (128 × 128 × 128………… × 127 times)} = 128^{4 × 32 × (128 × 128 × 128………… × 127 times)}

Now, let 32 × (128 × 128 × 128………… × 127 times) = m

∴ 128^{4 × 32 × (128 × 128 × 128………… × 127 times)} = 128^{4 × m}

Now, unit digit of 128^{4 × m}

∴ 128^{4 × m} = (8)^{4 × m}

For any value of n 8 ^{4 × m} always gives the unit digit as 6

∴ 6 is divisible by 2 and 3 both and we know that the number divisible by 2 and 3 both will also divisible by 6

Hence, option (4) is correct

Correct option is C) everything

Correct option is C) he’s tall enough to

Correct option is C) like

Given:

X is divisible by 2 and Y is divisible by 6

Formula Used:

Basic concept of number system

Calculation:

It is given that X is divisible by 2

∴ X is multiple of 2

⇒ x = 2a

And Y is divisible by 6

∴ Y is multiple of 6

⇒ Y = 6b

Now, (X + Y) = 2a + 6b = 2 × (a + 3b)

So, (X + Y) is multiple of 2

∴ It is divisible by 2

Hence, option (1) is correct

Given:

The Government of India nationalized the commercial banks to achieve the following objectives:

1. The main objective of nationalization was to attain Social Welfare. Sectors such as agriculture, small and village industries were in need of funds for their expansion and further economic development.

2. Nationalisation of banks helped to curb private monopolies in order to ensure a smooth supply of credit to socially desirable sections.

3. In India, nearly 70% of population lived in rural areas. Therefore it was needed to encourage the banking habit among the rural population.

4. Nationalisation of banks was required to reduce the regional imbalances where the banking facilities were not available. 

5. Before Independence, the numbers of banks were certainly inadequate. After nationalization, new bank branches were opened in both rural and urban areas.

6. Banks created credit facilities mainly to the agriculture sector and its allied activities after nationalization.

After New Economic Policy 1991, the Indian banking Industry has been facing the new horizons of competitions, efficiency and productivity

(I) High input costs:

1. The biggest input for farmers is seeds. 

2. Before liberalisation, farmers across the country had access to seeds from state government institutions. 

3. The institutions produced own seeds and were responsible for their quality and price. 

4. India’s seed market was opened up to global agri-businesses.

5. The deregulation of many state government institutions were closed down in 2003. 

6. Seed prices shot up and fake seeds made an appearance in a big way.

(II) Cutback in agricultural subsidies:

1. Farmers were encouraged to shift from growing a mixture of traditional crops to export oriented “cash crops” like chilli, cotton and tobacco. 

2. Liberalisation policies reduced the subsides on pesticide and fertilizer and elasticity. 

3. As a result prices have increased by 300%.

(III) Reduction of import duties:

1. With a view to open India’s markets, the liberalization reforms also withdrew tariffs and duties on imports.

2. By 2001, India completely removed restrictions on imports of almost 1500 items including food.

(IV) Paucity of credit facilities:

1. The lending pattern of commercial banks, including nationalised bank, drastically changed. As a result, loan was not easily adequate. 

2. This has forced the farmers to. rely on moneylenders who charge exorbitant rate of interest.
