Answer:
P = ₹ 625
A = ₹ 676
R = ?
T = 2 years = 2
As we know
A = P(1 + R/100)^n
\begin{gathered}676 = 625(1 + \frac{r}{100} ) {}^{2} \\ \frac{676}{625} = (1 + \frac{r}{100} ) {}^{2} \\ ( \frac{26}{25} ) {}^{2} = ( \frac{100 + r}{100} ) {}^{2} \\ \frac{26}{25} = \frac{100 + r}{100} \\ 26 \times 100 = 2500 + 25r \\ 25r = 2600 - 2500 \\ r = \frac{100}{25} \\ r = 4\end{gathered}
676=625(1+

r=4
Hence R = 4% Answer
