total amount will be the amount he got for being present minus the fine. hence
120x - 10y = 1880
120x - 10y = 1880

Let he be present for 'x' days
No: of days absent = 20 - x days
120*x - 10*(20-x) = 1880
120*x - 200 - 10*x = 1880
130*x = 2080
x= 16
Hence he was absent for 20-16 = 4 days.
Hope it helps.
