Answer 1

The correct option is E 294

Average number of post graduate employees in country 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 guaduate employees in country F, G and H
$=\frac{\frac{2788\times 75}{100}+\frac{3720\times 55}{100}+\frac{3360\times 80}{100}}{3}=\frac{2091+2046+2688}{3}=\frac{6875}{3}=2275$
$\therefore$ Required difference $=2275-1981=294$
