You can put this solution on YOUR website! Both: 1/4 = 25%
M(only) = 35-25 = 10%, E(only) = 30-25 = 5%
10% + 5% + 25% = 40% failed one or both
i)Find the percentage of students who failed in any of the subjects. 40%
ii)Find the number of students who passed in both the subjects. 60%
iii)if the number of students who failed only in English was 25,
find the total number of students? .10T = 25, T = 250
