Question Discussion & Solution

Total number of sarees = 40

Code number written on the 16^th saree = 85091

Code number written on the 29^th saree = 85091 + (29 – 16) = 85091 + 13 = 85104

The correct answer is 23.3 N to 30.12 N.

Key Points

•  The total area of Rajasthan is 3,42,239 sq km.
• The Rajasthan geographical location
  • 23.3 N to 30.12 North latitude
  • 69.30 E to 78.17 East longitude

Additional Information

• Rajasthan is the largest state in India.
  • The Present Rajasthan was made on 1 November 1956.
  • In geographical knowledge, it was once a part of Gondwana land.
    • Gondwana used to be the southern part of the supercontinent Pangea.
  • Rajasthan's shape looks like an irregular Rhomboid or Rhombus.

Joule is the SI unit of Energy.

Similarly,

Pascal is the SI unit of pressure.

Hence, pressure is the correct answer.

Additional Information 

* S.I Unit of Resistance is the Ohm.

* S.I Unit of Energy is Joule.

* S.I Unit of Volume is the Cubic meter.

* S.I Unit of Force is Newton.

* S.I Unit of Area is the Square meter.

* S.I Unit of Temperature is Kelvin.
Important Points 

There is a total of 9 S.I units.

1. 7 of them are fundamental units.

2. 2 of them are Supplementary units.

(E_Name, Salary_in_Lakhs) is the key

(E_Name, Salary_in_Lakhs) → {E_ID, E_Age, E_mail}

E_Name: Nitesh is repeated

Check only for Nitesh

(Nitesh, 9) → (XE005, 24, nitestSE@123)

(Nitesh, R) → (XE023, 24, nitestCE@123)

Since right hand side is not same

Therefore, R cannot be equal to 9

The correct answer is option 4) i.e. kg-1 m2

CONCEPT:

• Gravitational constant, G: G is a physical constant and therefore is universal in nature and has a constant value everywhere.
  • The value of G does not change with respect to time or place and is equivalent to 6.674 × 10-11 N m2 kg-2
  • The SI unit of G is N m2 kg-2
• Acceleration due to gravity, g: It is the acceleration of a body due to the force exerted from the earth's gravity.
  • It has a constant value of 9.8 m/s² within the surface of Earth.
  • The SI unit of g is m s^-2

EXPLANATION:

The unit of G = N m2 kg-2 = (mass × acceleration)m2 kg-2 = (kg × m/s²)m2 kg-2     (∵ N is the SI unit of force)

The unit of g = m s^-2​

Ratio, \(\frac{G}{g} = \frac{m^3 kg^{-1 }s^{-2 }}{m s^{-2}} =\) kg-1 m2
