- Given: Two equal sums lent at 10% and 8% simple interest p.a.

- Each amount after interest is Rs 36,900.

- The first sum is received 2 years earlier than the second.

- Understanding:

- Let the principal for both be Rs P.

- For first sum (10%) received in (T-2) years: Amount = P(1 + (10/100) \*(T-2)).

- For second sum (8%) received in T years: Amount = P(1 + (8/100) \* T).

- Results:

- Amount in both cases is same: 36,900.

- Creating two equations from the amount formulas and solving gives P.

- Calculation:

- Solving equations: P calculated is Rs 20,500.

- Correct Option:

- Option 1: Rs 20,500
