Answer: c

Exp: The Third Anglo-Maratha War (1817–1818) was the final and decisive conflict between the British East India Company and the Maratha Empire in India. The troops were led by the Governor General Hastings and he was supported by a force under General Thomas Hislop. It resulted in the formal end of the Maratha Empire and firm establishment of the British East India Company in entire India.

Diamond is harder than graphite because diamond has a more complex structure. Diamond's structure is like many pentagons connected together, each pentagon sharing a side with another pentagon or each pentagon sharing a point with another pentagon. All the points are linked together in some way. Graphite's structure is very loose, with its bonds forming layers.

The year 1921 marked the start of consistent population growth as revealed by the census. It was preceded by a decadal decline in growth rate during 1911-1921 which saw a net decrease of 0.3 per cent for the century as a whole. The year 1921 turned out to be demographic divide as in the post-1921 period; the population began to show signs of steady increase.

Uniform civil code of India is a term referring to the concept of an overarching Civil Law Code in India. A uniform civil code administers the same set of secular civil laws to govern all people irrespective of their religion, caste and tribe. In the small state of Goa, a civil code based on the old Portuguese Family Laws exists, and Muslim Personal Law is prohibited. This is a result of the liberation of Goa in 1961 by India, when the Indian government promised the people that their laws would be left intact.

Lumbini, the birthplace of Lord Buddha, is marked by a commemorative pillar erected by Mauryan Emperor Ashoka of India during his pilgrimage to the holy site in 249 BC. The inscription on the Ashoka Pillar indentifies the Sacred Garden spread over 9 sq. km -as the spot where the Enlightened One was born. Lumbini was known as Rummindei in Asoka's time.

• Recently, several European nations like France and Italy have asked tech giants like Google, Apple, Facebook, and Amazon (GAFA) to pay Digital service tax.
• Digital service tax covers online sales of goods and services. It includes policies that specifically target businesses that provide products or services through digital means. Hence statement 1 is correct.
• India was the first country to introduce a digital tax called ‘Equalisation Levy’ in 2016 at the rate of 6%. EL 1.0 was payable by Indian residents on online advertisement services purchased from nonresident companies.
• From 1 April 2020, the scope of equalization levy has been expanded to include a 2% levy on all online sales of goods or services into India by non-resident e-commerce operators (‘EL 2.0’). Hence statement 2 is correct.
• Recognizing the need to reform international tax rules for taxing digital companies such that countries get their fair share of taxes, the OECD has been working on proposals for new rules but so far has not arrived at a consensus on the final scope and manner of taxation.
• Meanwhile, many countries such as France (3% levy), Italy, Turkey, Austria, UK, Malaysia, Spain etc. have either proposed or implemented a unilateral digital tax applicable to digital companies, called as the ‘Digital Services Tax’ (‘DST’). Hence statement 3 is not correct.

• An open sky air service agreement allows for airlines from the two countries to have an unlimited number of flights as well as seats to each other’s jurisdictions. The National Civil Aviation Policy, 2016, allows the government to enter into an ‘open sky’ air services agreement on a reciprocal basis with SAARC nations as well as countries beyond a 5,000-kilometer radius from New Delhi.
• India entered into a complete open sky service agreement with the USA, Greece, Jamaica, Guyana, Finland, Spain and Sri Lanka.
  1. A nearly open sky service agreement has also been signed with the UK.
  2. A partial open sky was adopted for SAARC and ASEAN countries under which the designated airlines of these countries have been permitted to operate the unlimited number of services with third/fourth freedom traffic rights to 18 destinations in India. Hence options 1 and 2 are not correct.
• India has not entered any open sky agreement with G20 and BRICS group.
• Hence options 3 and 4 are not correct.

"Mero Rukh Mero Santati" 'New Green Initiative' was launched by the state of Sikkim.

3 + 1² + 1= 5

• Answer: Option b) Joy

  Solution:

• The words Worry, Anxiety, Anger, and Concern all represent negative emotions or states of unease.
• The word Joy is a positive emotion, making it different from the rest.

Only daughter of my mother → myself.

Hence, the woman is the mother of the man.

Mary is sitting immediate right to Reeta.

The digits on either side of the letter in each of the groups 1P6, 2T0, 1M3 and 1R8 indicate the place value of the letter in the alphabet.

This pattern is not followed by 2Y4.

Following the final seating arrangement, we can say that between I and H only one person sitting between them, if the counting is done from right of H.
Hence, the correct answer is option D.

Common Explanation:
Reference:
O is sitting second to the left of U and third to right of H.

Inference:
 
Reference:
D and I are immediate neighbors of  each other but one of them is an immediate neighbor of O. 
V is sitting second to the right of B.

Inference:
Here, we can place D and I as follows:

Reference:
G is sitting second to the left of D.
 
Inference:
To fix these two positions, we will have to place D to the immediate right of H. Thus, we get the final arrangement as:

The graph gives only the ratio of imports to exports for different years. To find the percentage increase in imports from 1997 to 1998, we require more details such as the value of imports or exports during these years.

Hence, the data is inadequate to answer this question.

The correct answer is C 
Let the incomes in 2000 of Companies X and Y be 3x and 4x respectively.
And let the expenditures in 2000 of Companies X and Y be E1 and E2 respectively.
Then, for Company X we have:
65 =[( 3x - E1 )/E1]×100 =>65/100 = (3x/E1) - 1 
=> E1 = 3x×( 100/165 ) .... (i)
For Company Y we have:
50 = [(4x - E2 )/E2]x 100 =>50/100= (4x/E1) - 1 => E2 = 4x×( 100/150 ) .... (ii)
From (i) and (ii), we get:
E1/E2=[3x ×(100/165)]/[4x×(100/150)]
E1/E2=15/22 (required ratio)

It would take another 5 years to double again. Thus, a total of 10 years to become four fold.

x = 48 * 8 = 384

So Option C is correct

12.5% of 350 * 8.4% of 250 = 6.25 * 7 * 21 = 918.75

So Option D is correct

LCM (15, 12, 21) = 420 second = 7 minutes

Answer – a) 5/8 Explanation : let total employees are 100 males = 40 and females = 60 (45 women earns more than 20000) total 60 employee earns more than 20000 per month, so number of males earns more than 20000 is 15 so fraction = 25/40 = 5/8

Answer – c) 20000 Explanation : (70/100)*T*(50/100)*(60/100) = 4200

Efficiency of A = 100 / 12 = 8.33%
Efficiency of B = 100 / 15 = 6.66%
Combined efficiency of A and B = 8.33 + 6.66 = 15%
Number of days taken by A and B, when working together = 100 / 15 = 
Note : Efficiency x Time period = Fixed amount of work
Also, in terms of percentage total work to be done is considered as 100% (in fraction it is 1), unless otherwise stated.
Alternatively : It can be done through unitary method, also.

The consecutive even numbers are a, b, c, d, e.
Clearly, b = a + 2, c = a + 4, d = a + 6, e = a + 8

Note: Whenever difference between any two consecutive terms is constant (means the series is an arithmetic series), the average of all the numbers is

(i) the middle number if the number of terms is odd.

(ii) the average of the middle two numbers if the number of terms is even.

Cost ∝ Weight²
Let original weight = 10x
Then, original cost = 100x²k (where k is proportionality constant)
After breakage weight = 1x + 2x + 3x + 4x
After breakage cost = kx²(1 + 4 + 9 + 16) = 30x²k
Now, (100 - 30)x²k = 70,000
Or, 70x²k = 70,000
Or, x²k = 1,000
Hence, original cost = 100x²k
= 100 × 1,000 = Rs. 1,00,000

Suppose after the reduction of Rs. 25, the shares of A, B and C are x, 3x and 2x, respectively.
Total money = 6x (after reduction)
Initially, share (A) + share (B) + share (C) = 735 … (1)
After reduction,
share (A) - 25 + share (B) - 25 + share (C) - 25 = 6x
⇒ share (A) + share (B) + share (C) - 75 = 6x ... (2)
From (1) and (2), we get
⇒ 735 - 75 = 6x
⇒ x = 660/6 = 110
Now, after deduction, C has, 2x = 2 × 110 = Rs. 220.
Before deduction, C had, 220 + 25 = Rs. 245

Assume CP of each pen as Re. 1.
So, his CP is Rs. 10 (∵ he purchased 10 pens and got 2 pens free).
The SP of each pen is Rs. 1.20 and he has 12 pens now.
So, he will get 12 x (1.20) = Rs. 14.4.
So, percentage profit 

SP = 1.1 CP
New cost price = 0.9 CP
New selling price = SP - 132
According to the given condition,

0.2 CP - 132 = 0.09 CP
0.11 CP = 132
CP = Rs. 1200
