Given,

I = ₹ 7840

T = 2 years

$\sf{R = 6 \frac{1}{4} \% = \frac{25}{4} \% \: p.a.}$

Let the sum be ₹ P.

We know that

$\sf{\implies{I = \frac{P \times R \times T}{100}}}$

$\sf{\implies{7840 = \frac{P \times 25 \times 2}{10 0\times4 }}}$

$\sf{\implies{7840 = \frac{P}{8}}}$

$\implies$P = 7840 × 8

$\implies$P = 62720

Hence, the sum is ₹ 62720.
