Question

Principal= ₹5000
Amount =₹20000
time = 4 years
Then find Rate.
It is compounded Annually.​

Answer 1

$\red{\tt{Principle = 5000}}$

$\red{\tt{Amount = 20000}}$

$\red{\tt{Time = 4years}}$

$\green{\bold{SI = Amount - Principle}}$

${\tt{SI = 20000 - 5000}}$

$\pink{\tt{SI = 15000}}$

$\green{\bf{SI = \frac{P \times R \times T}{100}}}$

${\tt{15000 = \frac{20000 \times 4R}{100} }}$

${\tt{15000 = 800R}}$

${\tt{ \frac{15000}{800} = R}}$

$\pink{\tt{18.75 percent = R}}$

Answer 2

$\underline \mathbb{QUESTION}$

Principal= ₹5000

Amount =₹20000

time = 4 years

Then find Rate.

It is compounded Annually

$\underline \mathbb{SOLUTION}$

$\underline \mathbb{GIVEN}$

》Principle = 5000

》Amount = 20000

》Time = 4 years

$\bold\green{\underline{Using\:formula-}}$

SI = AMOUNT - PRINCIPLE

SI = 20000 - 5000

SI = 15000

$= > SI = \frac{p \times r \times t}{100}$

$= > 15000 = \frac{20000 \times 4r}{1 00}$

$= > 15000 = 800r$

$= > \frac{15000}{800} = r$

$= > 18.75\% = r$

ANSWER= 18.75 PERCENT
