if the difference between simple interest and compound interest on a certain sum for 2 years at 10% is Rs. 50, then find the sum.

Correct option is C

given:

• Time (T) = 2 years

• Rate of Interest (R) = 10% per annum

• Difference between Compound Interest (CI) and Simple Interest (SI) = Rs. 50

We need to find the principal (P).

Use the Formula for CI - SI Difference

The difference between Compound Interest (CI) and Simple Interest (SI) for 2 years is given by:

Substituting the given values:
