    C) 47400              

    D) 47600

    E) 45600

    Correct Answer: D

    Solution :

    (d) The number of people who watch arrow in R, Q are T together
    \[=\left( \frac{50000\times 10}{100}+\frac{50000\times 22}{100}+\frac{20000\times 20}{100}+\frac{20000\times 16}{100}+\frac{50000\times 12}{100}+\frac{50000\times 14}{100} \right)\]
    \[=5000+11000+4000+3200+6000+7000=36200\]
    The number of people who do not watch arrow
    \[=34000+12800+37000\]
    \[=83800\]
    \[\therefore \]Required difference \[=83800-36200=47600\]
