yes , the correct ans is option B. We should not subtract the shaded area two times.
Ans 4:
Class : Class 8
it is extremely obvious that the shaded area needs to be subtracted twice as the shaded area is occurring in both shapes!!!!!!!! even if u find the area of the unshaded area separately, u are going to get the same answer!!!!!!!!!!!!!!!! it is definitely C!!!!!!! (C) (C)

The Shaded Area must be subtracted 2 times because it is overlapping the same area of both of the shapes.
Ans 6:

how did we get the area of WXYZ????????????????????
Ans 10:
Class : Class 7
it should be subtracted 2 times as the shaded area is coming in both the figures....we have taken the whole area of both the shapes
Ans 11:
Class : Class 8
yes answer should be B
