In a year, 70% of the smoking students are hospitalized from smoking - related complications, a total of 70 / 100 * 120 = 84 students. The number of smoking students who've not been hospitalized from smoking - related complications is 120 - 84 = 36. <hau> Tunanin: Idan aji yana da ɗalibai 300, akwai ɗalibai 40 / 100 * 300 = 120 masu shan sigari.
