Option 2 : Revise a plan

George Polya is known as the father of modern mathematical problem-solving.In 1945, he proposed a book "How to solve it", in which he explains all the four steps.

  •   According to Polya, the sequence of all the four steps in problem-solving is as:
    • Understand the problem
    • Devise a plan
    • Carry out the plan
    • Look back

 

  •  Understand the problem:
    • Children should put their efforts to understand the problem as to which type of the given problem is.
  • Devise a plan:
    • Plan a strategy by which the problem gets easily solved.
      • Example: Use symmetry, make a list, use the model, etc. 
  • Carry out the plan:
    • Persist with the plan that you have chosen, check each step and if the plan is continuous not working leave the plan and devise another plan.
  • Look Back:
    • Check the outcome (result) of the problem, and 
    • look back to see from which steps you get results.

Hence, we can conclude that 'Revise a plan' is not the correct option.

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. Jupiter has 2.5 times more mass than all the other planets of the solar system combined and is 11 times as large as Earth in diameter. P. Jupiter is so large that scientists believe it almost became a star: as the gases and dust contracted to the form the planet, Q. But there was not enough mass available to create the temperature needed to start a fusion reaction such as that of the Sun. R. Thus, Jupiter has been cooling down ever since.  S. gravitational forces created tremendous pressure and the temperature inside the core—as high as tens of thousands of degrees. 6. Even so, Jupiter radiates about as much heat as it receives from the Sun.?
