VENN DIAGRAM :: Last Set Qs 21-24 AIMCAT 1708
"The number of students in Class 8 who like only Mathematics is the same as the number of students in Class 9 who like both Science and Social."
The solution provided by TIME transforms this statement to a8 = f9 + g9 where a8 is students ho took only mathsin class 8 , f9 is students who study science and social in class 9 while g9 is students who study maths, science and social in class 9.
Query - Shouldn't a8 = f9 only? Why is g9 included here?
P.S- I am finding the statements in Venn Diagram quite confusing. Most of the times, this edge case- to select the common area of 3 parameters- is to be taken or not is causing issues.
Need some expert opinion here....
