Amit’s salary is ₹13,000 per month. He spends ₹4,000 on house rent, ₹2,000 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 his complete monthly savings for a birthday celebration.​

Correct option is B

Given:

Monthly salary = ₹13,000

House rent = ₹4,000

Bills = ₹2,000

In the birthday month, entire monthly savings are spent on celebration.

Concept Used:

Monthly savings = Salary – (House rent + Bills)

Annual savings = 11 months of savings (since 1 month is spent on celebration).

Formula Used:

Annual savings = 11 × (Salary − House rent − Bills)

Solution:

Monthly savings = 13,000 - (4,000 + 2,000) = 13,000 - 6,000 = 7,000

Annual savings for 11 months =11 × 7,000 = ₹77,000

Amit's annual savings is ₹77,000.
