A sum of Rs.12519 amounts to Rs. 17290 at 11.44% p.a. simple interest in a certain time.  What will be the simple interest (in Rs.) on a sum of Rs. 18297 at the same rate for the same time?

6973

Since rate and time are same for both conditions, simple interest will be directly proportional to principal

S.I. = 17290 - 12519 = 4771

P → 12519     :     18297

            13     :     19

S.I. →   13            ↓ x367

            ↓ x367      6973

         4771
