for example assume 100 students.
1.52 student pass in maths.
2.40 students pass in phy.
3.17 students pass in maths and phy
So.52-17=45 students pass in maths only
40-17=23 students pass in phy only
45+23+17=85 students pass in atleast one subject..
Ans is 100-85=15% students hasn't passed in both the subjects
