let the income be 11x and expenditure be 10x .
savings = 9000
therefore his savings : 11x - 10x = 9000
= x =Rs. 9000
therefore his income = 11×9000
= Rs.99000
Therefore per month salary = 99000÷12 =Rs. 8250
savings = 9000
therefore his savings : 11x - 10x = 9000
= x =Rs. 9000
therefore his income = 11×9000
= Rs.99000
Therefore per month salary = 99000÷12 =Rs. 8250
