Question

The schedule of 300 second year students was examined. It was found that 180 opted for Quantitative Aptitude course, 150 opted for a Verbal course and 50 opted for both a Quantitative Course & Verbal course. How many students opted for neither Quantitative Aptitude Course nor Verbal course?​

Answer 1

Let A be the set of people who opted for Quantitative Course

Let B be the set of people who opted for Verbal Course

AUB = A + B - (A n B)

x = 180 + 150 -50

x = 280

So, out of 300 students, 280 of them have opted for something or other. Therefore, 20 students have opted for none of the subjects.
