उत्तर
Given, Bhavya earns per month = ₹ 50000
She spends per month = 80% of 50000 = `80/100 xx 50000` = ₹ 40000
Then, her per month savings = 50000 – 40000 = ₹ 10000 ...[∵ Saving = Total income – Expenditure]
Also, given increment in monthly income = 20% of 50000
= `20/100 xx 50000`
= ₹ 10000
∴ Bhavya’s new income = 50000 + 10000 = ₹ 60000
Increase in expenditure = 20% of 40000
= `20/100 xx 40000`
= ₹ 8000
So, new expenditure = 40000 + 8000 = ₹ 48000
Now, Bhavya’s new savings = 60000 – 48000 = ₹ 12000
