To determine the two sums, we analyze the statements:
Statement A: The two sums are equal, but specific values are not given.
Statement B: The difference in simple interest is Rs. 250, providing a relationship but not the actual sums.
Statement C: The difference in compound interest is Rs. 275.60, also giving a relationship without specific values.
Combinations:
Combination (1): A with either B or C provides enough information to determine the sums, as it combines equality with interest differences.
Combination (2): A alone is insufficient for specific values.
Combination (3): B alone also lacks specific sum values.
Combination (4): Any single statement does not yield enough information.
So, the correct option is (A) A and either B or C.
