首先,由于近似数是指小数点后第四位四舍五入的数,因此最接近4万的数应该位于13459中间的数,即3和4之间。
我们可以列出所有由13459组成的五位数,并计算它们与4万之间的差值,然后找出最小的差值即可。
列出所有的五位数,可以得到:
13459, 13495, 13549, 13594, 13945, 13954, 14359, 14395, 14539, 14593, 14935, 14953, 15349, 15394, 15439, 15493, 15934, 15943, 19345, 19354, 19435, 19453, 19534, 19543, 41359, 41395, 41539, 41593, 41935, 41953, 43159, 43195, 43519, 43591, 43915, 43951, 45139, 45193, 45319, 45391, 45913, 45931, 51349, 51394, 51439, 51493, 51934, 51943, 53149, 53194, 53419, 53491, 53914, 53941, 54139, 54193, 54319, 54391, 54913, 54931, 59134, 59143, 59314, 59341, 59413, 59431, 91345, 91354, 91435, 91453, 91534, 91543, 93145, 93154, 93415, 93451, 93514, 93541, 94135, 94153, 94315, 94351, 94513, 94531, 95134, 95143, 95314, 95341, 95413, 95431
计算它们与4万之间的差值,可以得到:
-26541, -26505, -26051, -25506, -2055, -1986, 26041, 26005, 25561, 25107, 6065, 5997, 1551, 2094, 2559, 3107, 394, 463, -1761, -1692, -1231, -1163, -697, -629, 26541, 26505, 26061, 25607, 2107, 2039, 2607, 215, 1241, 1789, 2425, 2489, 1061, 1006, 961, 917, -1066, -1007, -575, -522, -486, -430, -219, -161, -20351, -20304, -19860, -19406, -14906, -14848, -10606, -10570, -10179, -9723, -6031, -5963, -6049, -5590, -6041, -5591, -996, -937, -621, -563, -207, -139, -10686, -10627, -10286, -9830, -7146, -7078, -1046, -986, -702, -144, 238, 302, 974, 1030, 1346, 1414, 3636, 3694, 4136, 4204, 4676, 4744
最小的正差值为394,位于14593,因此答案为1个。
