here are 250 students in a computer institute of these 180 have taken a course
in Pascal, 150 have taken a course in C++, 120 have taken a course in Java.
Further 80 have taken Pascal and C++, 60 have taken C++ and Java, 40 have
taken Pascal and Java and 35 have taken all 3 courses. So find (i) How many
students have not taken any course? (ii) How many study at least one of the
languages? (iii) How many students study only Java? (iv) How many students
study Pascal and C++ but not Java?
