A Correct answer
Explanation

Simple interest formula is A = P(1 + rt/100). Given A = 6000, r = 10, and t = 5, we have 6000 = P(1 + 0.5) = 1.5P. Solving for P gives P = 6000 / 1.5 = 4000.

AI explanation

The total amount after 5 years is Rs. 6000, so we use the formula A = P + (P * R * T / 100) to find the principal. Substituting the values gives 6000 = P + (P * 10 * 5 / 100), which simplifies to 6000 = P + 0.5P. This results in 6000 = 1.5P, and dividing both sides by 1.5 gives a principal of Rs. 4000.
