However, at the end of the year, 1 / 3 * 180 = 60 students had transferred from the school. The total number of students remaining in the school at the end of the year is 180 - 60 = 120. So, the answer is 120. <hau> Bayan sababbin ɗalibai 20 suka shiga ajin a farkon shekarar makaranta, adadin ɗalibai ya ƙaru zuwa 160 + 20 = 180.
