On what sum of  money will the difference between the simple interest and compound interest (Compound Annually) for 3 years at 5% per annum be Rs. 15.25?

Correct option is D

Effective rate of interest of 5% on S.I. =  5$$\times 3 = 15 {\%}$$

Effective rate of interest of 5% on C. I for 2 years = $$5+ 5+ \frac {5\times 5}{100}= 10.25{\%}\\$$

Effective rate of interest of 5% on 3 years = $$10.25+ 5+ \frac {10.25\times 5}{100} = 15.7625 {\%}$$

difference in S.I. and C.I = 15.7625- 15 = 0.7625%

0.7625% of P = 15.25

P= Rs. 2000
