Manjit’s salary is ₹10,000 per month. He spends ₹6,000 on house rent and ₹3,000 on bills, and the rest of the amount is his monthly savings. Find his savings (in ₹) in a year, if in the month of his birthday, he spent all his monthly savings on birthday celebrations.

Correct option is D

Given:
Manjit's salary is ₹10,000 per month.
He spends ₹6,000 on house rent and ₹3,000 on bills each month.
The remaining amount is his monthly savings.
In the month of his birthday, he spends all his monthly savings on birthday celebrations.
Formula Used:
Monthly saving = Salary - (House rent + Bills).
Yearly savings = (Monthly saving × 12) - (Savings spent on birthday).
Solution:
Monthly saving = 10,000 - (6,000 + 3,000) = 10,000 - 9,000 = 1,000
Yearly savings without birthday = 1,000 × 12 = 12,000
Manjit spends all his monthly savings (₹1,000) on birthday celebrations in the birthday month.
Yearly savings after birthday = 12,000 - 1,000 = 11,000
