# Bhavya earns ₹50,000 per month and spends 80% of it. Due to pay revision, her monthly income increases by 20% but due to price rise, she has to spend 20% more. Find her new savings.

**Solution:**

Given, Bhavya earns ₹50,000 per month and spends 80% of it.

Due to pay revision, her monthly income increases by 20%

Due to the price rise, she has to spend 20% more.

We have to find her new savings.

According to the question,

Monthly income = ₹50,000

Expenditure = 80%

Amount spent = 80% of 50,000

= (80/100) × 50,000

= 80 × 500

= ₹40,000

We know, savings = total income - expenditure

= ₹50,000 - ₹40,000

= ₹10,000

Monthly income after pay revision = ₹50,000 + 20% of ₹50,000

= 50,000 + (20/100) × 50,000

= 50,000 + 10,000

New income = ₹60,000

Increase in expenditure = 40,000 + 20% of 40,000

= 40,000 + (20/100) × 40,000

= 40,000 + 8,000

New expenditure = ₹48,000

New savings = new income - new expenditure

= 60,000 - 48,000

= ₹12,000

Therefore, the new savings is ₹12,000.
