Answer 2

$\huge{\boxed{\red{\bf{Question:-}}}}$

Sangita deposited some money in a bank for 5 years at 12.5% p.a. and got ₹15625 interest. Then find how much money she had deposited.

$\huge{\boxed{\red{\bf{Solution:-}}}}$

Let the amount of money deposited( P ) be = ₹ ${x}$

Rate of interest ( r ) = 12.5% p.a.

Interest ${( I )}$ = ₹15,625

time ( t ) = 5 years

${\boxed{\bf{{I}=\frac{P×r×t}{100}}}}$

${15625} =\frac{x × 12.5 × 5}{100}$

${15625 × 100} ={x × 62.5}$

${1562500}={62.5x}$

${x}=\frac{1562500}{62.5}$

${x}={25000}$

$\huge{\boxed{\red{\bf{Answer:-}}}}$

Sangita deposited ₹25,000.
