Peter ate some candy seven tablets

27 tháng 2 2017

Gọi:
Số kẹo Anna đã ăn là a
Số kẹo Mary đã ăn là b
Số kẹo Peter đã ăn là c
Theo bài ra ta có:
a + b + c = 22 (1)
a = 2 x b (2)
b < c < a (3)
Thay (2) vào (1) ta được: 
2 x b + b + c = 22
3 x b = 22 - c
3 x b = 21 + (1 - c) (4)
Vì 21 chia hết cho 3. Suy ra: (1 - c) chia hết cho 3
Vì (1 - c) chia hết cho 3, suy ra: c có thể nhận các giá trị là: 1, 4, 7, 10
Nếu c = 1 thì 3 x b = 21 + (1 - c) = 21. Suy ra: b = 7 (loại vì b > c)
Nếu c = 4 thì 3 x b = 21 + (1 - c) = 18. Suy ra: b = 6 (loại vì b > c)
Nếu c = 7 thì 3 x b = 21 + (1 - c) = 15. Suy ra: b = 5 (nhận)
Nếu c = 10 thì 3 x b = 21 + (1 - c) = 12. Suy ra: b = 4 và a = 2 x b = 2 x 4 = 8 (loại vì a < c)
Vậy: Số kẹo Peter đã ăn là 7 viên
