Let the savings of Ramesh, Suresh and Preeti be 16x, 17x and 12x.
Expenditure of Ramesh = 75% of income
So, Savings of Ramesh = 25% of income
We know
Saving = Income expenditure
16x = 25% of income
Similarly, Savings of Suresh = 20% of his income
So,
Savings of Preeti = 10% of her income
Given that total income of Ramesh, Suresh and Preeti is 8,07,000.
Savings of Ramesh = Rs 16
Savings of Suresh = Rs 85
Savings of Preeti = Rs 120
