Answer:
let he remains present for 'x' days
and absent for'y'days
According to given condition
X+Y=30......1
120X-10y=2300......2
therefore,. Y=30-X......3
substituting eq.3 in eq.1
we get 120X-10(30-X)=2300
120X-300+10X=2300
130X=2300+300=2600
x=20
and Y=10
so he remained present for 20 days and absent for 10 days
Hope it helps
