Let the salary be Rs x.
Spent on phone = 5%of x = x/20
Remaining amount = x -x/20 = 19x/20
Spent on fees = 18% of 19x/20
= 171x/1000
Remaining amount = 19x/20 - 171x/1000 = 779x/1000
According to statement
779x/1000 = 7790
Therefore, x = 10000
Spent on phone = 5%of x = x/20
Remaining amount = x -x/20 = 19x/20
Spent on fees = 18% of 19x/20
= 171x/1000
Remaining amount = 19x/20 - 171x/1000 = 779x/1000
According to statement
779x/1000 = 7790
Therefore, x = 10000
