真题文字详解(英文)
Upper Primary Division - Solutions
1. (Also MP4) There are 5 equal squares and 3 are shaded, hence (E).
2. The smallest of these numbers is 0.005, hence (D).
3. There are six seats in each row and 150 ÷ 6 = 25, hence (E).
4. (Also MP11) Alice has 2 × 50 + 3 × 20 + 8 × 5 = 200c. David has 4 × 20 + 6 × 10 = 140c. So Alice has 200 − 140 = 60c more than David, hence (B).
5. The largest number which can be formed is 54 321, the smallest is 12 345. Subtracting gives 41 976, hence (B).
6. One-third of 75 g is 25 g, so the special packet will weigh 75 + 25 = 100 g, hence (C).
7. (Also MP15) There are 5 different sizes of triangles as follows:
6 of this size
1 of this size
3 of this size
