What is the difference between the compound interest and simple interest calculated on an amount of RS.16200 at the end of 3 yr at 25% pa? (Rounded off to two digits after decimal)

Let required difference be RS. D

By formula,

D =\( \Large P\times \left(\frac{R}{100}\right)^{2}\times \left(3+\frac{R}{100}\right) \)

= \( \Large 16200\times \left(\frac{25}{100}\right)^{2}\times \left(3+\frac{25}{100}\right) \)

= \( \Large 16200\times \frac{625}{10000}\times {13}{4} \)

= \( \Large \frac{162\times 625\times 13}{4\times 100} \) =RS.3290.63
