Correct Answer: D
Solution :
Number of students for C++ from college S |
\[=2000\times \frac{35}{100}=20\times 35=700\] |
Number of students for SQL from college S |
\[=1800\times \frac{16}{100}=18\times 16=288\] |
\[\therefore \] Total number of students for C++ and SQL from college \[S=700+288=988\] |
Now, number of students for C++ from college R \[=2000\times \frac{19}{100}=380\] |
Number of students for SQL from college R |
\[1800\times \frac{28}{100}=504\] |
\[\therefore \] Total number of students for C++ and SQL from college \[R=380+504=884\] |
\[\therefore \] Required difference \[=988-884=104\] |
