Mr. Oberaiappered in CAT for four consecutive years, but coincidently each time his net score was 75. He told me that there was `1/3` rd negative marking for every wrong answer and 1 mark was alloted for every correct answer. He has attempted all the questions every year, but certainly some answer have been wrong due to stress and conceptual problems. Which is not the total number of questions asked for CAT in any year, in that period?

Options

A. 231
B. 163
C. 150
D. 123

Answer

C
