In a class of 150 students, students can either choose Electronics or Computer Science or neither (but not both). All students,whether they choose Electronics or Computer Science or neither, have to choose Mathematics. Every student has to choose atleast one subject. The sum total of the number of students who choose Electronics and the number of students choosing Computer Science is a multiple of 9.

Q1.If the number of students who choose only one subject is more than twice the number of students who choose two subjects, then what is the minimum value of the number of students who choose only one subject?
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?

A. 2 & 164 B.0 & 64 C.2 & 154 D. 5 & 37
