Question

A class took two tests, one in Physics and other in Maths. ${\left(\frac{1}{3}\right)}^{rd}$ class failed in Maths and ${\left(\frac{1}{2}\right)}^{th}$ class failed in Physics. 60% of those passed in Physics also passed in Maths. If 300 students took both the tests then how many students failed in both?

• A. 40
• B. 250
• C. 100
• D. 150

Answer 1

The correct option is A 40


Total number of students passed in atleast one subject
= 110 + 90 + 60 = 260
Therefore number of students failed in both the subjects
= 300 - 260 = 40
