Yujiang I and Yujiang II are two new rice varieties recommended by farmers of an agricultural science institute

Solution (1) suppose that the national purchase price of No.2 rice is x yuan / kg, then 1.6 = x (1-0.2), then x = 2
(2) Suppose that rice No.1 has m kg and rice No.2 has (1-0.2) m kg
Then 1.6m + 2.2m (1-0.2) = 1040, then M = 313.253
Then M + 0.8m = 1.8m = 563.855kg
Answer (1) the national purchase price of rice No. II is 2 yuan / kg of rice No. I, and the income of rice No. II is the same
(2) Xiaowang sold 563.855 kg of rice to the state last year
