Number of students who passed in Physics = No. of students who passed in (Physics only) + (Physics & Chemistry Only) + (Physics & Maths Only); Those who passed in Physics only is given (190). Those who passed in (Physics & Chemistry only) = (Physics + Chemistry) - (Passed in All three) i.e. = 326 - 206 = 120; Similarly, those who Passed in Phy & Math only = 366 - 206 = 160; and so on.
