Answer 1

Given:-

35% students failed in Science

42 % failed in social studies

32 % failed in both subjects

________________________

Formula used:-

Sci U Ss = n(Sci)+n(Ss)-n(Sci U Ss)

________________________

Solution:-

Let total Students be 100x

35x students failed in Science

42x failed in social studies

32x failed in both subjects

Using Formula of Sets.

percentage of total failed students

➾ n(Sci)+n(Ss)-n(Sci U Ss)

➾35x + 42x - 32x

➾45x

35% students failed in Science42 % failed in social studies32 % failed in both subjects________________________Formula used:-

Sci U Ss = n(Sci)+n(Ss)-n(Sci U Ss)

Sci U Ss = n(Sci)+n(Ss)-n(Sci U Ss)________________________

Sci U Ss = n(Sci)+n(Ss)-n(Sci U Ss)________________________Solution:-

Sci U Ss = n(Sci)+n(Ss)-n(Sci U Ss)________________________Solution:-Let total Students be 100x

Sci U Ss = n(Sci)+n(Ss)-n(Sci U Ss)________________________Solution:-Let total Students be 100x35x students failed in Science

Sci U Ss = n(Sci)+n(Ss)-n(Sci U Ss)________________________Solution:-Let total Students be 100x35x students failed in Science42x failed in social studies
