Minh has some candies . He gives to his friend seventeen candies and gives to his dad twenty - nine candies . Now , he has sixteen candies . How much candies does he have before ?
Dịch đề: Minh có một số cái kẹo. Minh cho bạn Minh 17 cái kẹo và cho bố Minh 29 cái kẹo. Bây giờ, Minh còn lại 16 cái kẹo. Hỏi lúc đầu Minh có bao nhiêu cái kẹo?

Jane buys 22 candies for three children, Anna, Mary and Peter. Anna eats twice as many candies as Mary. Peter eats more candies than Mary but less than Anna. How many candies does Peter eat?
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
Peter ăn 7 cái kẹo đó bạn
