Question

find tne compound interest on $ 25600 for 2years at 6.25 pet annum​

Answer 1

Step-by-step explanation:

Principal = Rs. 25600

Rate = 6.25%

Time = 2 years

To Find:

The compund interest

Solution:

Using the formula,

⇒ \sf{CI = P \left(1 + \dfrac{R}{100}\right)^T}CI=P(1+100R)T

Substitute the values,

⇒ \sf{CI = Rs.\:25600 \left(1 + \dfrac{6.25}{100}\right)^2}CI=Rs.25600(1+1006.25)2

Solve the brackets,

⇒ \sf{CI = Rs.\:25600 (1.0625)^2}CI=Rs.25600(1.0625)2

Multiply 1.0625 by 1.0625,

⇒ \sf{CI = 25600 \times 1.12890625}CI=25600×1.12890625

Multiply the numbers,

⇒ \sf{CI= Rs.\:28900}CI=Rs.28900

∴ So, the compound interest is Rs. 28900.
