A principal amount grows to Rs. 1344 in two years under simple interest. What is the compound interest on the same principal, at the same interest rate, over the same duration?

Explanation

Since the final amount after two years under simple interest is given, the principal and rate are unknown. Without knowing either the principal or the interest rate, it is impossible to calculate the compound interest for the same period. Therefore, the data provided is insufficient to find the compound interest.
