A Correct answer
Explanation

Under compound interest, the amount grows from Rs. 500 after 2 years to Rs. 700 after 3 years, so 700/500 = 1.4 and the annual rate is 40%. The relation distance = speed * time is also true, so both statements are true.

AI explanation

For statement A, the compound interest rate is calculated as the difference between the third and second year amounts divided by the second year amount, which is 200 divided by 500, yielding exactly 40%. Statement B is the standard fundamental formula relating distance, speed, and time. Therefore, both statements A and B are true.
