Avinash's monthly salary is ₹50,000 and his monthly expenditure is ₹18,000. Radha's monthly salary is ₹60,000 and her monthly expenditure is ₹24,000. Find the ratio of Radha's savings to Avinash's saving's.

Correct option is A

Given:
Avinash's monthly salary = ₹50,000
Avinash's monthly expenditure = ₹18,000
Radha's monthly salary = ₹60,000
Radha's monthly expenditure = ₹24,000
Formula Used:
Savings = Salary - Expenditure
Ratio = Radha's Savings / Avinash's Savings
Solution:
1. Calculate Avinash's monthly savings:
Avinash's Savings = ₹50,000 - ₹18,000 = ₹32,000
2. Calculate Radha's monthly savings:
Radha's Savings = ₹60,000 - ₹24,000 = ₹36,000
3. Find the ratio of Radha's savings to Avinash's savings:
Ratio = Radha's Savings / Avinash's Savings
Ratio = ₹36,000 / ₹32,000
Ratio = 36 / 32
Ratio = 9 / 8
Required ratio = 9 : 8
