Question

How many failed in Social Science only?

• A. $15$
• B. $21$
• C. $30$
• D. $42$

Answer 1

The correct option is A $15$

Consider the diagram attached
A is failed in social science
B is failed in mathematics
C is failed in science
we have to find failed only in social science
i.e, the orange portion $1=A-(4+5+7)$
7 is failed in all the subject
4 is failed in social science and science i.e, passed in mathematics
5 is failed in social science and mathematics i.e, passed in science
failed in social science $=175-(60+52+48)=15$
Hence, option 'A' is correct.
