Marks: +1, -0

Every month, Kritika spends

30 \%

of her income on home rent and

60 \%

of the rest on household expenditure. If she saves

₹ 6300

per month, what is her total monthly income?

Solution:

Let the initial amount of Kritika be

₹ 100

.
spent on home rent

=30 \%

Remaining amount

=70 \%

Household expenditure

=60 \%

of the

70 \%

=\;{60 × 70}/{100}=42

Remaining amount

=28 \%

(she shaves)
So,

\;\; 28 \%=6300

100 \%=\;{6300}/{28} × 100=₹ 22,500
