its 9000, because 6300/7=900......and 7+3 s 10...therefore 9000*10 =90000...thats not actually a mathematical way of solving but my own idea...

ratio of expenditure and saving = 7:3
let expenditure = 7x
savings = 3x
but 7x = $6300 given
x = 6300/7
x= 900
therefore
savings = 3x = 3*900 =2700
total income = expenditure+savings
= 6300+2700
=$9000
