A student has to choose 3 subjects out of Maths, Physics, Chemistry, Biology and Computer Science. Find the total possible number of ways of choosing.

In a class , 40 student like Maths, 50 students like Physics and 60 students like Chemistry. 30 students like both Maths and Physics, 20 students like both Physics and Chemistry and none of them like both Maths of Chemistry . Find the total number of students who like only Maths, only Physics and only Chemistry.

Comprehension: In a class of 25 students of Mathematics and Computer Science, 12 students have taken Mathematics. Out of this, 8 have taken Mathematics but not Computer Science. What is the number of students who have taken Computer Science but not Mathematics?

In a school, students must take at least one of these subjects: Maths, Physics or Chemistry. In a group of 50 students, 7 take all three subjects. 9 take Physics and Chemistry only, 8 take Maths and Physics only and 5 take Maths and Chemistry only. Of these 50 students, x take Maths only, x take Physics only and x + 3 take Chemistry only. Draw Venn diagram, find x, and hence find the number taking Maths.

In a class of 35 students, 18 students opt Maths, 12 students opt Maths but not Science. Find the number of students who opt both subjects. Also find the number of students who opt Science but not Maths. It is given that each student opt atleast one subject.

In a class of 35 students, 18 students opt Maths, 12 students opt Maths but not Science. Find the number of students who opt both subjects. Also find the number of students two opt Science but not Maths. It is given that each student opt atleast one subject.

A class has 172 students. The following data shows the number of students opting one or more subjects: Mathematics 125, Physics 95, Chemistry 65 Mathematics and Physics 55 Mathematics and Chemistry 53 Physics and Chemistry 48 Mathematics, Physics and Chemistry 43 The number of students who opted only Physics is

In a University there are 1200 students studying four different subjects, Mathematics, Statistics, Physics and Chemistry. 20% of the total number of students are studying Mathematics, one-fourth of the total number of students are studying Physics, 320 students are studying Statistics and remaining students are studying Chemistry. Three-fifth of the total number of students studying Chemistry are girls. 150 boys are studying Mathematics. 60% of students studying Physics are boys. 250 girls are studying Statistics. In which subjects is the difference between the number of boys and girls equal ?
