• Important Cricket Tournaments in India:  the Ranji Trophy, the Duleep Trophy, the Vijay Hazare Trophy, the Deodhar Trophy, the Irani Trophy and the NKP Salve Challenger Trophy.

Concept:

Vitamins:

• Vitamins are organic compounds that are present in minute amounts in natural foodstuffs.
• Most vitamins come from food because the body either does not produce them or produces very little.
• Vitamins are of two types.
  • Fat-soluble vitamins- Vitamins A, D, E, K.
  • Water-soluble vitamins- Vitamin C and all the B vitamins. 

• There are 13 vitamins - A, C, D, E, K, and B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, B6, B12, and folate), each of them have a different job.
• Vitamin A, D, E, K are Fat-Soluble vitamins and are stored in fat cells while vitamins B and C are water-soluble vitamins that are not stored in your body.
• The liver acts as a storage site for vitamin A, D, E, K, and B12 for the times when they may be lacking in the diet.
• Vitamin D acts as a hormone, produced by the kidneys it helps to control the concentration of calcium in the blood and is vital for the development of strong bones.
• Water-soluble vitamins like Thiamine, folate, biotin, riboflavin are synthesized by gut bacteria.

Explanation:

• Vitamin E is a mixture of four vitamins called α, β, γ and δ tocopherols among which α tocopherol is the most active.
• Characteristics:
  • Light yellow fat soluble in oils.
  • Stable to heat and oxidation.
• Sources are cotton seed oil, maize oil, peanut oil and wheat germ oil.
• Deficiency causes damage to the reproductive system.

Hence, Vitamin E is also called tocopherol.

Additional Information 

• Riboflavin is vitamin B₂.
• Calciferol is vitamin D.
• Thiamine is vitamin B₁.

Similar figure repeat in every second step. Each time the first figure reappear it rotates one space anticlockwise direction and each time the second figure reappear it rotates one space clockwise direction.

From the above explanation we can conclude (1), (3) and (5) are same figure with anticlockwise rotation.

The correct answer is Udaipur.

• Sorghum research centre has been established in Vallabhnagar Udaipur in Rajasthan.

Key Points

• Sorghum/Jowar is used as food grains.
• The highest Jowar production in the country is in Maharashtra.
• Whereas Rajasthan holds the fourth position in the country.
• Rajasthan has the highest production of Jowar in the central part.
• While Ajmer district ranks fifth in Jowar production.

Additional Information

• The major variety of Jowar in the state is PV-96.
  • Maximum Producing District - Nagaur, Ajmer, Pali.
  • Climate - Warm temperature is required.
  • Rainfall - 35 -150cm
• Alcohol and Beer are made from Sorghum.

• Power: The rate of work done by the electric energy is called power. It is denoted by P.
  • The SI unit of power is the watt (W).
  • Watt is a small unit that's why kilowatt-hour is used as the unit for electrical energy.
• 1 unit of electric energy: When one-kilowatt load works for 1 hour then the energy consumed is called 1 unit of electricity.

1 Unit of electricity = 1 kWh = 1000 Watt-hour = 3.6 × 106 J

1 Kilo-watt = 1000 Watt

• 1 Watt: The energy consumption rate of 1 joule per second is called 1 watt.

EXPLANATION:

Since 1 hr = 3600 sec

1 kWh = 1000 W-hr = 1000 × 3600 watt sec = 3.6 × 10⁶ J 

​So option 1 is correct.
