answer option B = 45 right answer
so if 45 answer is right, then the difference (315-263) will be the mark obtained for wrong answer
which is 52. and it should be a multiple of 4 or divisible by 4
thus 45*7 - 13*4 = 263
means 45 right answer and 13 wrong answer, total 45+13= 58 attempted, it is given in the question.
