Question

find the simple intrest on Rs. 4500 at 10 percent per annum for 73 days also find the amount.​

Answer 1

GiveN :

• Principle (P) = Rs. 4500
• Rate of interest (R) = 10 %
• Time = 73 days = 73/365 = 1/5 year

To FinD :

• Simple Interest
• Amount

SolutioN :

Formula for simple interest is :

$\dashrightarrow \boxed{\tt{SI \: = \: \dfrac{P \: \times \: R \: \times \: T}{100}}} \\ \\ \dashrightarrow \tt{SI \: = \: \dfrac{4500 \: \times \: 10 \: \times \: \dfrac{1}{5}}{100}} \\ \\ \dashrightarrow \tt{SI \: = \: \dfrac{900 \: \times \: 10}{100}} \\ \\ \dashrightarrow \tt{SI \: = \: 90} \\ \\ \underline{\sf{\therefore \: Simple \: Interest \: is \: Rs. \: 90}}$

______________________

$\dashrightarrow \boxed{\tt{Amount \: = \: SI \: + \: Principle}} \\ \\ \dashrightarrow \tt{Amount \: = \: 90 \: + \: 4500} \\ \\ \dashrightarrow \tt{Amount \: = \: 4590} \\ \\ \underline{\sf{\therefore \: Amount \: is \: Rs. \: 4590}}$

$\huge \tt {GIVEN:}$

• Principle (P) = Rs. 4500
• Rate of interest (R) = 10 %
• Time = 73 days = 73/365 = 1/5 year

$\huge \tt {SOLUTION:}$

______________________

$\tt {FORMULAS~USED:}$

➠SI=P×R×T/100

➠Amount=SI+Principle

______________________

➩SI= 100/4500×10× 5

➩SI= 100/900×10

➩SI=90

∴ Simple Interest = ₹90

______________________

➩Amount=90+4500

➩Amount=4590

∴ Amount = ₹4590
