SSC CGL level Question Set 25, Arithmetic Percentage, Ratio and Proportion 4

25th SSC CGL level Question Set, 4th on topic Arithmetic Percentage, Ratio and Proportion

SSC CGL question set 25 percentage ratio proportion 4

This is the 25th question set of 10 practice problem exercise for SSC CGL exam and 4th on topic Arithmetic Percentage, Ratio and Proportion. Students should complete this question set in prescribed time first and then only refer to the corresponding solution set.

We will repeat here the method of taking the test if you have not gone through it already. 

Method for taking the test and get the best results from the test set:

  1. Before start, go through the tutorials Basic concepts on fractions and decimals part 1, Basic concepts on Ratio and Proportion, Arithmetic problems on mixing liquids and based on ages, Basic and Rich Percentage Concepts for solving difficult SSC CGL problems, or any other short but good material to refresh your concepts if you so require.
  2. Answer the questions in an undisturbed environment with no interruption, full concentration and alarm set at 12 minutes.
  3. When the time limit of 12 minutes is over, mark up to which you have answered, but go on to complete the set.
  4. At the end, refer to the answers given at the end to mark your score at 12 minutes. For every correct answer add 1 and for every incorrect answer deduct 0.25 (or whatever is the scoring pattern in the coming test). Write your score on top of the answer sheet with date and time.
  5. Identify and analyze the problems that you couldn't do to learn how to solve those problems.
  6. Identify and analyze the problems that you solved incorrectly. Identify the reasons behind the errors. If it is because of your shortcoming in topic knowledge improve it by referring to only that part of concept from the best source you get hold of. You might google it. If it is because of your method of answering, analyze and improve those aspects specifically.
  7. Identify and analyze the problems that posed difficulties for you and delayed you. Analyze and learn how to solve the problems using basic concepts and relevant problem solving strategies and techniques.
  8. Give a gap before you take a 10 problem practice test again.

Important: both practice tests and mock tests must be timed, analyzed, improving actions taken and then repeated. With intelligent method, it is possible to reach highest excellence level in performance.
