Question

Riya earns Rs. 30,000 p.m. She spends
10% of her income on taxes. Of the
remaining, she spends one-third on
rent, half on petrol, one third on
electricity and the rest goes in the
savings. What percentage of Riya's
income is she able to save?​

Answer 1

Answer:

10% of 30,000

=10/100×30, 000

=3,000

Rs 3,000 is the amount which is spent on income tax.

30,000-3,000=27, 000

(1/3) ×27,000= 9,000

Rs 9,000 is spent on rent

27,000-9000=18,000

(1/2) ×18,000=9,000

Rs 9,000 is spent on petrol

18,000-9,000=9,000

(1/3) ×9,000=3,000

Rs 3,000 is spent on electricity

9,000-3,000=6,000

Rs 6,000 goes in saving

(6000/30000) ×100=20%

20% of her savings goes in savings
