A sum of money at compo^ interest will amount to Rs.650 at the end of the first year and Rs.676 at the end of second year. The amount of money is
1). Rs.1.300
2). Rs.650
3). Rs.1.250
4). Rs.625
.Principal = P (let)
Rate = R% per annum
A=P($1+\frac{R^{T}}{100}$)
650= P($1+\frac{R^{}}{100}$)
$\frac{650}{P}$=P($1+\frac{R^{}}{100}$)...(I)
Again, 676 = P($1+\frac{R^{2}}{100}$)
P= $\frac{650\times650}{676}$= 625
