Question

if geetha earn 12000 per month and savings is 3000 then find ratio of expenditure to savings

Answer 1

income=12000
savings=3000
therefore,expenditure=12000-3000
=9000
ratio of expenditure to that of savings
=9000:3000
=9:3
=3:1

Answer 2

Earning of Geetha=12000
Saving of Geetha=3000
Expenditure by Geetha=Earning of Geetha-Savings of Geetha-Savings
=12000-3000=9000
So, ratio of expenditure to savings =9000/3000=3:1
