Gce Model Questions Vol1 2021 Mathematics Question 18
Practice objective / multiple choice question 18 from the 2021 Gce Model Questions Vol1 Mathematics examination.
In a survey of 170 students, the numbers studying Mathematics (M), Physics (P) and Chemistry (C) are as follows: \(n(M)=90\), \(n(P)=80\), \(n(C)=70\). The numbers studying each pair of subjects are \(n(M\cap P)=45\), \(n(M\cap C)=40\), \(n(P\cap C)=35\). Let \(x\) be the number of students who study all three subjects. It is known that the number of students who study none of the three subjects equals the number who study exactly two subjects. Find \(x\).
