Question

compound interest questions sovle it

Answer 1

Given
in 2 yr amount =₹6272

In 3 yr amount =₹7024. 64

One is interest=7024.64-6272

=752.64


Interest =pxrxt /100

752.64=6272 x R x 1/100

R=
$\frac{752.64 \times 100}{6272}$
R=12%


Now

A=p(r+1/100)^t

6272=p(1+12/100)²

6272=p(112/100)²

6272=px1.2544

P=6272/1.2544

P=₹5000


Rate of interest =12%

Sum=₹5000
