Answer 1

Answer:

left money 120

spend money 90%

means not spent is 10%

so

120=10x/100

120*100/10=x

1200 rupees she gets per month

Answer 2

Step-by-step explanation:

suppose, amount sent by Alka=x

Amount spend by Alka=90% of x

=90/100×x

=9x/10

saving =amount -investment

120=x-0.9x

120=0.1x

x=120/0.1

x=₹1200
