20% of the total number of students in a school play football. How many students do not play football if the total number of students in the school is 7600 ?
Let the greater and the smaller number be g and s respectively.gs = 2560g + s exceeds g - s by 64 i.e., g + s - (g - s) = 64i.e., 2s = 64 => s = 32.g = 2560/s = 80.
