In a test containing 16 questions , contestants get a base core of 20 points for taking the test. 5 points
for each correctly answered question and 2 points for each unanswered question.An incorrectly answered
question is worth 0 points.Of the following scores which one is not attainable

a)96                                  b)97                        c)94                         d)95

• 1. 15 corrected and 1 uncorrected
  20+5*15+0=95
  
  2.15 corrected and 1attempted
  20+5*15+2=97
  
  3. 14corrected+2attempted
  20+14*5+2*2=94
  
  so 96 is not possible
• 9 years agoHelpfull: Yes(20) No(0)
• a. 96 is not possible
• 9 years agoHelpfull: Yes(14) No(0)
• 14*5=70
  2*2=4
  Base poin=20
  20+70+4=94
• 9 years agoHelpfull: Yes(4) No(1)
• a) 96
  
  If 15 questions were answerd and one incorrect the score becomes 20(base score)+(15*5)+0=95
  so option D is false.
  same way
  20+(15*5)+2=95
  20+(14*5)+4=94
  so option A is correct
• 9 years agoHelpfull: Yes(1) No(0)
• 1. 15 corrected and 1 uncorrected
  20+5*15+0=95
  
  2.15 corrected and 1attempted
  20+5*15+2=97
  
  3. 14corrected+2attempted
  20+14*5+2*2=94
  
  4.14corrected+3attempted = 17 (but total ques =16)
  20 + 14*5 + 2*3=96
  
  so 96 is not possible
