Show Answer
Answer:
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 $
