A sum of Rs. 9800 amounts to Rs. 12600 at 9.33% p.a. simple interest in a certain time. What will be the simple interest (in Rs.) on a sum of Rs. 25200 at the same rate for the same time?
Answer & explanation
Correct answer: option 3
Since rate and time are same for both conditions, simple interest will be directly proportional to principal.
S.I. = 12600 - 9800 = 2800
P → 9800 : 25200
7 : 18
S.I. → 7 ↓ x400
↓ x400 7200
2800
