Question Discussion & Solution

The correct answer is First.

• In the year 2017-18, Rajasthan was the largest millet producing state of India.

Key Points

• Rajasthan was followed by Maharashtra and Karnataka.
• The year 2023 will be observed as the International Year of Millets. 
• The Central Government declared 2018 as the year of millets. 
• Millet Mission comes under the National Food Security Mission (NFSM) which was launched in October 2007. 
• Millets include Jowar and ragi etc.

Additional Information 

• Types of Crops in India:
  • Kharif: Sown in June/July, harvested in September/October, e.g., rice, jowar, bajra, ragi, maize, cotton, and jute.
  • Rabi: Sown in October/December, harvested in April/May, e.g., wheat, barley, peas, rapeseed, mustard grains.
  • Zyad: They are raised between April/June, e.g., melons, watermelons, cucumbers, toor, leafy and other vegetables.

Total number of boxes of matchsticks = 3600

Total number of cartons = 10

Let the number of packets in one carton be x.

⇒ Number of packets in 10 cartons = 10x.

Number of boxes of matchstick in a packet = 30

⇒ Number of boxes of matchstick in 10x packets = 30(10x) = 300x

So, we have:

Total number of boxes = Number of boxes of matchstick in 10x packets

⇒ 300x = 3600

⇒ x = 12

The correct answer is Nitrification.

Key Points

• The process of conversion of ammonia into nitrate nitrogen is called nitrification.
• It is done in two steps- Nitrite formation, Nitrate formation.
• Nitrite formation- Ammonia are oxidized to nitrites by Nitrococcus, Nitrosomonas.

Additional Information

• The nitrogen cycle has four steps-
  • Nitrogen Fixation- Conversion of molecular nitrogen into the inorganic nitrogenous compound.
  • Ammonification- Conversion of the dead organic nitrogenous compound into ammonia.
  • Nitrification- Oxidation of ammonia into nitrates.
  • Denitrification- Nitrites or nitrates converts back into molecular nitrogen.

The correct answer is 2 * 1024 * 1024 Bytes.

• One thousand and twenty-four kilobytes (1024 KB) is equal to one megabyte (1 MB), where 1 MB is 10242 bytes.
  • ​So 2 Mb equals to 2 * 1024 * 1024 Bytes.

Key Points

• The cache memory
  • The cache memory is located very close to the CPU, either on the CPU chip itself.
  • It can be located on the motherboard in the immediate vicinity of the CPU.
  • So data can be read from it (and written to it)more quickly than with normal RAM. 

Additional Information

• Cache
  • A cache is a special storage space for temporary files that makes a device, browser, or app run faster and more efficiently. 
• There are three general cache levels:
  • L1 cache, or primary cache:
    • It is extremely fast but relatively small and is usually embedded in the processor chip as CPU cache.
  • L2 cache, or secondary cache:
    • It ​is often more capacious than L1.
  • Level 3 (L3) cache 
    • It is a specialized memory developed to improve the performance of L1 and L2.

Y → Position value of Y is 25 which square of 5.

P → Position value of P is 16 which square of 4

I → Position value of I is 9 which square of 3

D → Position value of D is 4 which square of 2

Therefore, square of 1 is 1 and that corresponds to A.
