is the answer 12? case (1) all the 30 questions are correct.marks = 150. now the natural nos.less than 150 which is not possible for any student to get are : 1) 149. (for a wrong answer 2 marks are deducted.so if 29 questions are right then he scores 145 and for 1 wrong the result becomes 145-2=143.or else 145 if he left one question.) 2) 148(the same scenerio here also.) 3) 147 4) 146 5) 144 6) 142 7) 139( 28*5= 140,for 2 wrong answer the result is (140-4=136 or for 1 wrong it becomes 138) 8) 137 9) 134 10) 132 11) 129 12) 127. if any one knows any better process or the perfect one plz share it. |
