Answer 1

Step-by-step explanation:

Let the original income be Rs. x.

Expenses = Rs. 80

∴Savings=Rs.20∴Savings=Rs.20

Increase in expenditure = 37 12=752%12=752%

His present expenditure = Rs.(80+30) = Rs.110

Increase in his Income =1623%=1623%

∴∴ His present income = Rs.3503Rs.3503

∴∴ His present savings = Rs.(3503−100)=Rs.203(3503−100)=Rs.203

∴∴ Required percentage savings

=2033503×100=2033503×100

=203×3350×100=203×3350×100

=407=407

=557%
