Question

a certain sum of money was deposited in a bank for 5 years the bank paid simple interest at the rate of 12.5% per annum find the money deposited if the interest received by the depositor is 1,200?​

Answer 1

$\sf \Large Solution!!$

$\sf \large Given:$

$\sf \to Rate(R)=12.5\%$

$\sf \to Time(T)=5\:years$

$\sf \to Interest(I)=Rs\:1,200$

$\sf \large to\:find:$

$\sf \to Principle(P)$

$\sf \large So,$

$\sf \to I=\dfrac{P\times R\times T}{100}$

$\sf \to 1,200=\dfrac{P\times 12.5\times 5}{100}$

$\sf \to 1,20,000=62.5P$

$\sf \to \dfrac{1,20,000}{62.5}=P$

$\sf \to P=Rs\:1,920$

Answer 2

Let the Principal be ₹P

Rate (R) = 12.5% p. a.

Time (T) = 5 years

Simple Interest (SI) = ₹1200

$\boxed {SI = \frac{PRT}{100}}$

$1200 = \dfrac{P \times 125 \times 5}{100 \times 10}$

$1200 = \dfrac{ P\times 5}{4 \times 2}$

$P = \dfrac{1200 \times 4 \times 2}{5}$

$\underline{ \underline{P = ₹ \: 1920}}$
