Answer:
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 $
