    E) 149

    Correct Answer: B

    Solution :

    Total number of female students who have enrolled for course on Linux
    \[=1500\times \frac{42}{100}=15\times 42=630\]
    Total number of students from college Q for Linux
                \[=1500\times \frac{20}{100}=300\]
    Now, female students from college
                \[Q=630\times \frac{20}{100}=126\]
    \[\therefore \] Male students of Linux from college
    \[Q=300-126=174\]
