Answer:

Here, Principal (P) = Rs.12,500, Time (T) = 3 years, Rate of interest (R) = 12% p.a.

Simple interest for Fabina = \frac{P\times R\times T}{100}=\frac{12500\times12\times3}{100}=\ Rs.\ 4,500

P×R×T

12500×12×3

= Rs. 4,500

Amount for Radha, P = Rs. 12,500, R = 10% and n = 3 years

Amount (A) = P\left(1+\frac{R}{100}\right)^nP(1+

= Rs. 16,637.50

\therefore∴ C.I. for Radha = A – P

= Rs. 16,637.50 – Rs. 12,500 = Rs. 4,137.50

Here, Fabina pays more interest

= Rs. 4,500 – Rs. 4,137.50 = Rs. 362.50
