Correct Answer: C
Solution :
Number of students for Java from college P |
\[=2400\times \frac{27}{1000}=648\] |
Number of students for SQL from college P |
\[=1800\times \frac{24}{100}=432\] |
\[\therefore \] Total number of students for Java and SQL from college \[P=648+432=1080\] |
Number of students for Java from college S |
\[=2400\times \frac{18}{100}=432\] |
Number of students for SQL from college S |
\[=1800\times \frac{16}{100}=288\] |
\[\therefore \] Total number of students for Java and SQL from college \[S=432+288=720\] |
\[\therefore \] Required ratio |
\[=\frac{1080}{720}=\frac{108}{72}=\frac{36\times 3}{36\times 2}=\frac{3}{2}=3:2\] |
