Exp: In 1609/ 1610 Emperor Jehangir issued  permitting the English to establish a factory at Surat and in 1613 the English East India Company's factory was set up at Surat.

A mirage is a naturally occurring optical illusion or phenomenon in which light rays are bent due to refraction in layers of air of varying density. The image usually is upside down, enhancing the illusion that the sky image seen in the distance is really a water or oil puddle acting as a mirror.

A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapour. it contains mercury vapour and argon. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light. A fluorescent lamp converts electrical power into useful light more efficiently than an incandescent lamp.

The Rajasthan Atomic Power Station (RAPS) is located at Rawatbhata in Chittorgarh district of the state. Commissioned on 16 December 1973, it is operated by the Nuclear Power Corporation of India. Currently, RAPS has six Pressurized Heavy Water Reactor (PHWR) units operating with a total installed capacity of 1,180MW.

• Cropping pattern means the proportion of area under different crops at a point of time. Factors that affect cropping pattern are:
  1. Physical characteristics of a region like soil, climate, rainfall etc.
  2. Availability of irrigation facilities determine not only which crops can be grown but also whether double or triple cropping will be possible of not.
  3. Price incentives (like MSP) and other income maximization schemes.
• Indian experience:
  1. A shift in crops from food grains to non-foodgrains reflects a change from subsistence cropping to commercial cropping. In India, area under foodgrains came down from 75%in 1950 to almost 66% in 2010. This trend clearly shows that the shift was not substantial.
  2. Shifting little area from staple to high value in the suitable region lead to a sizable increase in the returns for farmers. High value crops offer comparatively better growth in terms of value of output contribution as compared to the staple crops. Yet some key challenges exists like:
  3. Water intensive crops like sugarcane and paddy are mostly grown in the naturally water starved areas of the country for example paddy in Punjab and sugarcane in Maharashtra because of policy measures like Input subsidies (power, water, fertilizer) and MSP. Hence statements 1 and 2 are correct.
  4. Over extraction of water than recharge led to decline in groundwater table, availability of groundwater cannot be the stimulating factor for a skewed cropping pattern. Hence statement 3 is not correct.
  5. The demand of commodity plays an important role but without appropriate infrastructure and logistic support, without favorable government policies, it does not act as a stimulating factor. Hence statement 4 is not correct.

GST revenues hit ₹1.59 lakh crore in January 2023, the second-highest monthly collection on record.

Mizoram will be exporting 'Bird's eye chilli' to the United States for the first time.

Uttarakhand signed an MoU to build a ropeway to the Yamunotri temple.

The Indian pair Anirudh Chandrasekhar and N Vijay Sundar Prashanth stormed into the doubles final of the Bengaluru Open ATP challenger tournament.

Explanation:
Let's break down Sam's movements step by step:

1. Sam walked 10 m towards West from his house.
2. He then turned to his left (which is South when facing West) and walked 5 m.
3. Next, he turned to his left again (which is East when facing South) and walked 10 m.
4. Finally, he turned to his left one more time (which is North when facing East) and walked 10 m.

At the end of these movements, Sam is facing North from his starting point. So, the correct answer is B: North.

2*2 – 2 = 2
2*2 + 4 = 8
8*2 – 6 = 10

4 * 1 + 2 = 6
6 * 2 – 4 = 8
8 * 3 + 6 = 30
30 * 4 – 8 = 112
112 * 5 + 10 = 570

Explanation:

• The set of words consists of items used for writing or related to paper.
• Book, Paper, Pencil, and Pen are all directly involved in the writing process.
• However, Sharpener is distinct as it is a tool used to sharpen pencils, making it less directly related to writing.
• Thus, the word that stands out as different is Sharpener.

Brother of mother means maternal uncle. Hence only nephew of Aamir's maternal uncle means Aamir himself. Therefore Sonia is the wife of Aamir.

Cat, Dog, Tiger and Lion are carnivores, while Elephant is a herbivore.

Clearly, vowels A, E, I, O, U are coded as 1, 2, 3, 4, 5 respectively. Each of the consonants in the word is moved one step forward to give the corresponding letter of the code. So, the code for ACID becomes 1D3E.

When everyone faces the center, a person’s immediate right is the neighbor counterclockwise from them. In the clockwise order A, B, U, V, O, P, the person just before V is U, so U is to V’s immediate right.

The exports are more than the imports imply that the ratio of value of imports to exports is less than 1.

Now, this ratio is less than 1 in years 1995, 1996, 1997 and 2000.

Thus, there are four such years.

3/14 of 5/13 of 6/7 of 3822 = 3 * 5 * 6 * 3 = 270

So Option C is correct

Answer – b) 100 Explanation : (20/100)*t*t = 2000 (total students = t)

Efficiency of A + B = 33.33% = (100 / 3)

Ratio of efficiency of A and B = 3 : 1
∴ Efficiency of A = 
∴ Number of days taken by A = 4 = 100 /25
Alternatively :

∴ Difference in days = 2x = 8
 ► ⇒ x = 4 and 3x = 12

Therefore number of days taken by A, working alone = 4 days
Alternatively : 

Now, you can use the options, or solve the equations to get the value of x which is equal to 4.

Let G be the number of goals scored and p be the number of international players.
G α p²
∴ G = kp²
When 4 players play, G₁ = k × 4² = 16k
When 6 players play, G₂ = k × 6² = 36k
G₂ - G₁ = 5 goals
∴ 5 = k (36 - 16) or k = ¼
When 8 players play,
G = (1/4) × 8² = 16

Let the quantity of milk in one vessel be x litres.
In 10 vessels, quantity of milk = 10x litres
For Rs. 5 per litre, total cost of milk = 10x × 5 = Rs. 50x
For Rs. 6 per litre, total cost of milk = 10x × 6 = Rs. 60x
From the given information, we can say that
60x - 50x = 350
⇒ 10x = 350
⇒ x = 35 litres

Opening the pyramid, you will get

According to cosine formula,
