plz give correct answer friends​

Answer 1

Given :-

• Simple Interest= 450Rs
• Time = 5years
• Rate = 5%

To find:-

• Principal

Formula to know:-

${SI} = \dfrac{P \times T \times R}{100}$

• SI = Simple Interest
• P = Principal
• T = Time period
• R = rate

Solution :-

Just plugging the values

${SI} = \dfrac{P \times T \times R}{100}$

${450} = \dfrac{P \times 5 \times 6}{100}$

${450} = \dfrac{30P}{100}$

${450} = \dfrac{3P}{10}$

Do Cross multiplication

${450 \times 10 = 3P}$

${4500 = 3P}$

${P} = \dfrac{4500}{3}$

P = 1500 Rs

So, Principal is 1500 Rs

Answer 2

Answer:

Principal amount 450+ 450*5*6/100 = 585
