70 + 56 + x = 60% of all three subjects
70 + 56 + x = 60% of 400
x = 240 – 126 = 114
% = 114/200 * 100 = 57%

Given:
English marks = 70%
Biology marks = 56%
Maximum marks in both papers = 100
Marks in all three subjects = 60%
Maximum marks in Maths paper = 200

To find: Percent score in Maths

Solution:
Let's assume the maximum marks in English and Biology to be x.

So, percentage marks obtained in English = (70/100) x
Percentage marks obtained in Biology = (56/100) x

Total marks obtained in English and Biology = (70/100)x + (56/100)x = (126/100)x

As the maximum marks in Maths is 200, the marks obtained in Maths = (60/100) x 200 = 120

Total marks obtained in all three subjects = (126/100)x + 120

But the total marks obtained in all three subjects = (60/100) x (100 + 100 + 200) = 180

So, (126/100)x + 120 = 180

(126/100)x = 60

x = (60 x 100)/126 = 47.6 (approx)

Hence, the maximum marks in English and Biology is approximately 47.6.

Now, let's calculate the percentage marks obtained in Maths.

Total marks obtained in all three subjects = (60/100) x (100 + 100 + 200) = 180

Maximum marks in all three subjects = 100 + 100 + 200 = 400

Percentage marks obtained in all three subjects = (180/400) x 100 = 45%

Therefore, the percentage marks obtained in Maths = 45% - [percentage marks obtained in English (70%) and Biology (56%)] = 45% - 63% = -18%

As we cannot have a negative percentage, we can assume that there is an error in the given data.

Hence, the answer is none of the above options.
