Question

Find Amount and C. I if Principal = rupees 72000 , Time = 3 years , Rate = 3/2 % ​

Answer 1

Answer:

Amount=Rs. 75,288 Rupees and compound interest = Rs. 3288 Rupees

Step-by-step explanation:

Given,

   $Principal = Rs \hspace{2mm} 72000 \\ \\ Time = 3 \hspace{1mm}years \\ \\ Rate\hspace{1mm} of\hspace{1mm} interest \hspace{1mm} per\hspace{1mm} annum= 3/2 % ​$%

The formula for amount calculation is

      Amount $A=P(1+\frac{R}{100})^n$

By substituting the value of Principle, time and rate of interest in the formula .

$Amount=72000(1+\frac{3}{200})^3\\ \\ Amount=72000(\frac{200+3}{200} )^3\\ \\ Amount=72000(\frac{203}{200})^3\\ \\ Amount=\frac{72000\cdot 83,65,427}{8000000} \\ \\ Amount=75,288.843$

Amount =75,288 Rupees

We know that,

        $Amount = principle + interest\\ \\ Compound interest= Amount-principle\\ \\ Compound interest =75,288-72000\\ \\ Compound interest=3,288 \hspace{2mm}Rupees$

Compound interest= 3,288 Rupees
