    E) 294

    Correct Answer: E

    Solution :

    Average number of post graduate employees in countries A, B and D
    \[=\frac{\frac{2568\times 75}{100}+\frac{2880\times 65}{100}+\frac{3575\times 60}{100}}{3}\]
    \[=\frac{1926+1872+2145}{3}=\frac{5943}{3}=1981\]
    Average number of post graduate employees in countries F, G and H
    \[=\frac{\frac{2788\times 75}{100}+\frac{3720\times 55}{100}+\frac{3360\times 80}{100}}{3}\]
    \[=\frac{2091+2046+2688}{3}=\frac{6825}{3}=2275\]
    \[\therefore \]Required difference \[=2275-1981=294\]
