Question Discussion & Solution

The relation among given numbers is that every number is the sum of the squares of the digits of the previous number:

936 → 9² + 3² + 6² = 81 + 9 + 36 = 126

126 → 1² + 2² + 6² = 1 + 4 + 36 = 41

41 → 4² + 1² = 16 + 1 = 17

17 → 1² + 7² = 1 + 49 = 50

50 → 5² + 0² = 25

25 → 2² + 5² = 4 + 25 = 29

The correct answer is 10.4%.

• Rajasthan is spread over approximately 10.4%  .
  • The state covers an area of 342,239 square kilometres.

​Additional Information

• Geography of Rajasthan
  • It is the largest Indian state by area and the seventh-largest by population.
  • Rajasthan is located on the northwestern side of India, where it comprises most of the wide and inhospitable Thar Desert (also known as the "Great Indian Desert") and shares a border with the Pakistani provinces of Punjab to the northwest and Sindh to the west, along the Sutlej-Indus river valley.
  • It is bordered by five other Indian states: Punjab to the north; Haryana and Uttar Pradesh to the northeast; Madhya Pradesh to the southeast; and Gujarat to the southwest.
  • Its geographical location is 23.3 to 30.12 North latitude and 69.30 to 78.17 East longitude.
  • The Tropic of Cancer passes through the southernmost tip of the state.

For alphabet: Increase by + 4

 D + 4 → H + 4 → L + 4 → P + 4 → T + 4 → X

For Number: Decrease number by - 4

23 – 4 → 19 – 4 → 15 – 4 → 11 – 4 → 7 – 4 → 3

The correct answer is To adjourn the Legislative Assembly.

• Article 174, a governor shall summon the House at a time and place, as she or he thinks fit.
• Article 174 (2) (a) says a governor may from “time to time” prorogue the House.
• Article 174 (2) (b) allows her or him to dissolve the Legislative Assembly.
• The speaker of the Legislative assembly has the right to adjourn the Legislative Assembly.

Key Points

• According to Article 153, each state in the country will have a governor.
• Also, a person can be appointed as the Governor of two or more states.
• According to Article 155, the Governor is appointed by the President.
• The powers of Governor :
  • The governor has the right to call the state assembly in any emergency and dissolve it at any time.
  • He also has the right to call a joint sitting of the two houses.
  • He has the right to repeal any bill to be passed in the State Legislative Assembly, sent back for review and sent to the President.
  • This means that no bill in the state assembly can be passed without the consent of the governor.
  • The Governor also has the task of issuing any ordinance during emergencies in the state.

CONCEPT:

• Power: The rate of work done is called power.
  • It is denoted by P.
  • Mathematically it is written as

\(Power\;\left( P \right) = \frac{{\;W}}{{t}}\)

CALCULATION:

Given - mass of 1^st person (m₁) = 80 kg, mass of 2^nd person (m2) = 60 kg, time (t₁) = 12 sec, and time (t2) = 11 sec​

• The power to take an object to a certain height in 12 sec by 1^st person is 

\(\Rightarrow P_1 = \frac{mgh}{t}=\frac{80gh}{12}\)       ----(1)

• The power to take an object to a certain height in 11 sec by 2^nd person is 

\(\Rightarrow P_1 = \frac{mgh}{t}=\frac{60gh}{11}\)       ----(2)

On dividing equations 1 and 2, we get

\(\Rightarrow \frac{P_1}{P_2} =\frac{\frac{80gh}{12}}{\frac{60gh}{11}}=\frac{11}{9}\)
