If the respective ratio between the number of students from college P, Q, R and S who were able to pass the exam for C++ was 3 : 4 : 2 : 3, what is the number of students who were able to pass the exam for C++ from college Q?

    A) 200                              

    B) 420

    C) 340                              

    D) 300

    E) 400

    Correct Answer: E

    Solution :

    Number of candidates who were able to pass the exam for \[C++=2000\times \frac{60}{100}=1200\]
    Given, number of candidates who were able to pass the exam for C++ from colleges P, Q, R, and S
                \[=3:4:2:3\]
    \[\therefore \] Number of students who were able to pass the exam for C++ from college Q
    \[=\frac{4}{3+4+2+3}\times 1200=\frac{4\times 1200}{1200}=4\times 100=400\]
