11 số nguyên dương liên tiếp được viết trên bảng. Maria xóa một trong những số. Nếu tổng 10 số còn lại là 2012, Maria xóa số nào?
Bài giải:
Gọi số đầu tiên là a thì 11 số liên tiếp là a + 1 đến a+ 10
tổng của 11 số đó là 11 a + 55
Vì tuấn xóa đi 1 số nên tổng của 10 số sẽ thuộc [10a + 45 , 9a + 55]
..........

Tuấn xoá đi 1 trong 10 số nguyên
dương liên tiếp. Tổng của 9 số
còn lại bằng 2006. Hỏi Tuấn đã
xoá đi số nào?
gọi số đầu tiên là a thì 10 số liên tiếp là a + 1 đến a+ 9
tổng của 10 số đó là 10a + 45
vì tuấn xóa đi 1 số nên tổng của 9 số sẽ thuộc [9a+36 , 9a + 45]
ta có 2006 = 9.222 + 8 = 9.218 + 44 => a = 218 => số đã xóa là 218 .10 + 45 - 2006 = 219
