The money invested is Rs. 3000.

Step-by-step explanation:

Given :

Time = 3 years

To find :

The sum of money

Solution :

Here :

• Principal = P
• Rate = 5%
• Simple Interest = 450
• Time = 3 years

$\bigstar \: \boxed{\sf{SI = \frac{Principal \times Rate \times Time}{100}}}$

$\sf{\implies} \: {450 = \dfrac{P\times 5 \times 3}{100}} \\ \\ \sf{\implies} \: {450 = \dfrac{15P}{100}} \\ \\ \sf{\implies} \:15P = 450 \times 100 \\ \\ \sf{\implies} \:15P = 45000 \\ \\ \sf{\implies} \:P = \dfrac{45000}{15} \\ \\ \sf{\implies} \:P = 3000$

Principal = Rs. 3000

$\therefore$ The money invested is Rs. 3000.
