Solution
Monthly salary of a person = Rs 12,000
Monthly expenditure = 8,500
Saving of the person = (12,000 – 8500) = Rs 3,500
(i) Ratio between salary and expenditure
`12000:8500=12000/8500=120/85=24/17=24:17`
(ii) Ratio between expenditure and saving
`8500:3500=8500/3500=85/35=17/7`
(iii) Ratio between Savings and salary
`3500:12000=3500/12000=35/120=7/24=7:24`
