A.79 B.67 C.105 D.None of these

Q2.If the number of students who choose only one subject is a multiple of 13 and the number of students who opt for Electronics is 24, what percent of the total students opt for Computer science?
A.25% B.32% C30% D.40%

Q3.1f the number of students who choose only one subject is a multiple of 13, and the number of students who choose Electronics is a non-zero multiple of 8, then what can be the minimum and maximum values of the number of students who choose both Mathematics and Computer Science?

A.8 and 64 B.16 and 76 C.0 and 72 D.0 and 64

Q4.If in the next year, additional 90 students are enrolled and in the combined batch, the number of students who choose only one subject is a multiple of 13, and the number of students who choose Electronics is a non-zero multiple of 8, then what can be the minimum and maximum values of the number of students who choose both Mathematics and Computer science?
