Directions: Answer the questions on the basis of information given below.
In the Regional Admission Test (RAT) - 2012 there were three sections, Reasoning Ability (RA), Arithmetic Ability (AA) and Technical Aptitude (TA), each comprising 25 multiple choice questions. Each correct response carried four marks and each incorrect response carried a negative one mark as penalty. There were no marks for the questions not attempted. Also, there were four form numbers of test papers viz., AAA, BBB, CCC and DDD in which the sequence of the three sections (RA, AA and TA) were different and they were labeled as Section I, Section II and III.
After the test, it was observed that there were some printing mistakes in the test papers, so the questions having mistakes were omitted while calculating the scores. But it was also found that the number of valid questions (questions having no mistakes) were not the same for the same section (e.g. RA) through all the four form numbers. So the RAT - 2012 organizing committee formulated a procedure to calculate the score for each section as follows:
  • First, the actual score is calculated considering only the valid questions as per the formula: 4 X number of correct responses - number of incorrect responses.
  • The percentage score for the section obtained is expressed as a percentage of the maximum possible marks in that section - i. e., the marks one can score in the section if he/she gets all the valid questions in that section correct.
For example:
In form DDD since there were only 23 valid questions in RA, the percentage score in RA for Form DDD is the actual marks obtained by the candidate as a percentage of the total valid marks in that section, i.e., 4 X 23 = 92 marks.
Hence, if the candidate's Test Form No. is DDD and he/she got 10 correct responses and 2 incorrect responses, then his/her actual score is 38 while his/her percentage score is 38/92 x 100 = 41.30%.
Given below is the table of the maximum possible marks for each section of each of the four test forms in RAT - 2012
Given below are the performances of five candidates in RAT-2012. TA is the number of total responses (for both valid and invalid questions) by the candidate in the particular section while TI is the number of total incorrect responses (for valid questions only) by the candidate in that particular
The candidate's Total Percentage Score is the simple average of the three sectional percentage scores obtained by him/her. N, x, y and z are natural numbers.
What could be the minimum possible total percentage score (approx) of C if his form was not AAA?
For example:
If a candidate's percentage scores in the three sections are 55%, 23.96% and 41.67%, then his/her Total Percentage Score would be
= 40.21%
Q. If there is at least one invalid question in the AA section of Form AAA, then which of these could be the possible sectional percentage score for the section?(I)72
(II)75
(III)80
(IV) 84
  • a)
    (I) and (IV) only
  • b)
    (II) and (III) only
  • c)
    (III) and (IV) only
  • d)
    All the 4 are possible
Correct answer is option 'B'. Can you explain this answer?

Directions: Answer the questions on the basis of information given be...
To understand the effect of invalid questions on the score of a candidate, consider the following table
From the above table, it can be inferred that to minimize the percentage score, a candidate should attempt the maximum invalid questions possible while to maximize the percentage score, a candidate should not attempt invalid questions.
For each of the given options, check
So if total valid marks are multiples of 20, then this percentage score is possible.
This also is a possible percentage score.
Hence, the correct option is (b).

Also, there were four form numbers of test papers viz., AAA, BBB, CCC and DDD in which the sequence of the three sections (RA, AA and TA) were different and they were labeled as Section I, Section II and III.After the test, it was observed that there were some printing mistakes in the test papers, so the questions having mistakes were omitted while calculating the scores. But it was also found that the number of valid questions (questions having no mistakes) were not the same for the same section (e.g. RA) through all the four form numbers. So the RAT - 2012 organizing committee formulated a procedure to calculate the score for each section as follows: First, the actual score is calculated considering only the valid questions as per the formula: 4 X number of correct responses - number of incorrect responses. The percentage score for the section obtained is expressed as a percentage of the maximum possible marks in that section - i. e., the marks one can score in the section if he/she gets all the valid questions in that section correct. For example:In form DDD since there were only 23 valid questions in RA, the percentage score in RA for Form DDD is the actual marks obtained by the candidate as a percentage of the total valid marks in that section, i.e., 4 X 23 = 92 marks.Hence, if the candidate's Test Form No. is DDD and he/she got 10 correct responses and 2 incorrect responses, then his/her actual score is 38 while his/her percentage score is 38/92 x 100 = 41.30%.Given below is the table of the maximum possible marks for each section of each of the four test forms in RAT - 2012Given below are the performances of five candidates in RAT-2012. TA is the number of total responses (for both valid and invalid questions) by the candidate in the particular section while TI is the number of total incorrect responses (for valid questions only) by the candidate in that particularThe candidate's Total Percentage Score is the simple average of the three sectional percentage scores obtained by him/her. N, x, y and z are natural numbers.What could be the minimum possible total percentage score (approx) of C if his form was not AAA?For example:If a candidate's percentage scores in the three sections are 55%, 23.96% and 41.67%, then his/her Total Percentage Score would be = 40.21%Q. If there is at least one invalid question in the AA section of Form AAA, then which of these could be the possible sectional percentage score for the section?(I)72(II)75(III)80(IV) 84a)(I) and (IV) onlyb)(II) and (III) onlyc)(III) and (IV) onlyd)All the 4 are possibleCorrect answer is option 'B'.
