Answer 1

We have,

• Principal = 256
• Time = 1 year
• Rate = 100%, as it is compounded quaterly rate = 100/4 = 25%

So, the compound interest will be;

= C.I = p${( 1 + \dfrac{r}{100})}^{4 × n}$ - p

= C.I =256 × ${( 1 + \dfrac{25}{100})}^{4 }$ - 256

= C.I = 256 × ${( \dfrac{125}{100})}^{4 }$ - 256

= C.l = 256 × ${( \dfrac{5}{4})}^{4 }$ - 256

= C.l = 256 × 625/ 256 - 256

= C.l = 625 - 256

= C.I = 369

Thus, the interest when compounded quaterly will be Rs.369.
