Unit squares are arranged to form a rectangular grid that
is m units wide and n units tall,where m and n are
positive integers with 2n < m < 3n.The region below
one of the diagonals of the rectangle is shaded as shown.
For certain pairs m and n,there is a unit square in the
grid that is not completely shaded but whose shaded area
is greater than 0.999.The smallest possible value of mn
for which this is true satisfies
(A) 496 \x14 mn \x14 500
(B) 501 \x14 mn \x14 505
(C) 506 \x14 mn \x14 510
(D) 511 \x14 mn \x14 515
(E) 516 \x14 mn \x14 520

题目如下:
单位正方形被排列成宽为m,高为n的矩形网格,m,n均为正整数且2n
单位正方形排列,形成一个矩形网格
单位是米宽,高n个单位,其中m和n
2n < m < 3n.同为2n的正整数“米”3晚。 该区域以下
.对矩形的对角线1所示的阴影。
对于某些对m和n,有一个单位正方形
网格是不完全遮盖,但其阴影区
mn最小的可能值的时间
为此,这是真正的满足
(A) 496 mn 500 (甲)496分钟...
