Ok
Now Let His Total Salary Per Month Be Rs x.
Now
Amount Given To His Sons = 1/100*x = x/100
Now Amount Received By Elder Son = 80/100*x/100 = 80x/10000 = 8x/1000 = x/125
Now Its Given That He Spends 80% Of His Share
So Amount Saved = 100-80 = 20%
20/100*x/125 = x/625
Now This Equal Rs 20
x/625 = 20
x = Rs 12500
