Concept
Basic Percentage
Application
Let the number of students in school X = 100K
No of students from school Y who appeared in the same examination = 250K
According to the question
Students failed in school X = 30K
Total students failed from X and Y together = 350 K x 20/ 100 = 70K
Students failed from school Y = 70 K - 30K = 40K
% failed from Y = 100 x 40 K/ 250K = 16%
