    B) 116

    C) 128                              

    D) 104

    E) 96

    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 \[=988-884=104\]
