$28 \cdot 201000$ households have annual incomes ranging from $8200 to $98000. Due to an error, the highest income was recorded as $980000 in the computer. By how much does the average value of the incorrect data differ from the average value of the correct data?
(A) 882 .
(B) 980 .
(C) 1078 .
(D) 482000 .
(E) 882000 .
(6th American Junior High School Mathematics Examination, 1990)
［Solution］Obviously, the input data was over-calculated:
$$
980000-98000=882000 \text { (USD) },
$$

For 1000 households, the average over-calculation per household is
$$
882000 \div 1000=882 \text { (USD) }.
$$

Therefore, the answer is $(A)$.
