Question

principal = ? R% = 6 % Time =8 interest=? amount = 248​

Answer 1

Given:-

R%=6%

Time=8 years

Amount= ₹248.

Solution:-

We know that,

$\tt A=P( 1+ \dfrac{R}{100})^n$

By using this formula, we can find out principal.

$\implies \tt 248=P(1+ \dfrac{6}{100})^8$

$\implies \tt 248=P(1+ \dfrac{3}{50})^8$

$\implies \tt 248=P( \dfrac{50+3}{50})^8$

$\implies \tt 248=P( \dfrac{53}{50})^8$

Rest of the calculation is given in attachment.

And principal is equals to x in attachment.

And after that, to calculate Interest, you use the formula to calculate it.

Answer 2
