真题文字详解(英文)
2019 AMC Upper Primary Solutions 1. (Also J1) 201 - 9 = 192, hence (D). 2. (Also MP5) From the top, Caz scored 8, then Evan scored 7, hence (E). 3. Adding millions, thousands and units, the number is 6000000 + 203000 + 6 = 6203006, hence (C). 4. (Also MP7) A♥ is under 4♥, 4♥ is under 5♥, 5♥ is under 3♥, and 3♥ is under 2♥. So the order of dropping is A♥ 4♥ 5♥ 3♥ 2♥, hence (B). 5. (Also MP9) From 1st Street to 4th Street, she walks 3 blocks east. From 1st Avenue to 3rd Avenue, she walks 2 blocks north, hence (D). 6. (Also MP10) In Jake's hand, there are (A) 3 hearts, (B) no diamonds, (C) 2 spades, (D) 2 picture cards, and (E) 1 even-numbered card. All 7 cards are equally likely, so (A) is the most likely, hence (A). 7. We look at each solid, checking first for 5 faces, then 9 edges. (A) has 6 faces; (B) has 8 faces; (C) has 5 faces, but only 8 edges; (D) has 5 faces and 9 edges; (E) has 4 faces; hence (D). 8. (Also J7) Halfway to Renmark is 230 ÷ 2 = 115 km. Blatchetown is 9km short of this, and Waikerie is 33 km beyond, so Blatchetown is closest to halfway, hence (D). 9. 25 - 8.25 = 16.75, hence (B). 10. There are 9 divisions for 42 - 24 = 18 on the scale, so each division is 2 units. So the number at P is 24 + 6 × 2 = 36, hence (D).
