最佳解答:

No comment : 250 x 16% = 40 people Have comment : 250 - 40 = 210 people Like Crispy Cracker : 210 x 62.5% = 131.25 = 131 people (四捨五入) Dislike Crispy Cracker : 210 x (100% - 62.5%) = 78.75 = 79 people (四捨五入)

其他解答:

NUMBER OF PEOPLE INTERVIEWED = 250 No comment is 250 * 16% = 40 Have comment is 250 – 40 = 210 Assume Like people = L, dislike people = D L + D = 210 62.5% more people like Crispy Cracker than disliked them (L – D) / D = 62.5% L = 1.625D L + D = 210 1.625D + D = 210 D = 80 L = 130 Like people is 130 Dislike people is 80
