B) 276
C) 316
D) 342
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 \[=2275-1981=294\] |
