Expert please tell me the answers of the question before giving the answer

Dear Student,
For the figure i) , it is clearly seen that the quadrilateral has been divided into 4 equal oartitions out of which 3 of those are shaded and 1 of them is not shaded.
Thus, the shaded percentage is $\frac{3}{4}\times 100=75\%$
Kindly post the remaining queries in another thread.
Regards.
