B Correct answer
Explanation

The simple interest is proportional to the deposit amount. From the table, 1000 Rs gives 80 Rs interest, meaning the interest rate is 8 percent per year. To earn 280 Rs interest, the deposit must be 280 / 0.08 = 3500 Rs.

AI explanation

The table shows a direct variation between the deposit and the simple interest, where an Rs. 1000 deposit earns Rs. 80. Setting up a proportion to find the deposit for Rs. 280 gives 1000/80 = Deposit/280. Solving this equation gives Deposit = (1000 x 280) / 80. This calculates to Rs. 3500.
