Question

deepak invests an amount of 21250 for 6 years .at what rate of simple interest will be optain the total amount of 26350 at the end of 6 years​

Answer 1

We will use the formula of Simple Interest that is

$S=\frac{PRT}{100}$

We have been given P=₹21250, T=6 years, S=₹(26350-21250)=₹5100.

$5100=\frac{(21250).(6).R}{100} \\51000= (2125)(6)R\\R=\frac{51000}{(2125)(6)} \\R= 4$

Rate is 4%

Answer 2

Answer:

Rate of simple interest (R) = 4%

Step-by-step explanation:

Given:

• Invested amount or Principal (p) = Rs.21,250

• Time = 6 years

• Total amount = Rs. 26,350

To Find:

Rate of simple interest (R)

Solution :

Simple Interest = SI

Find the Interest :

★ SI = Total Amount - principal

⇒ 26,350 - 21,250

⇒ 5,100

Hence,

⇒ SI = 5,100

__________________________

Now,

Find the rate of simple interest:

★ R = (SI × 100 / P × T) %

⇒ R = 5,100 × 100 / 21,250 × 6) %

⇒ R = (5,10,000 / 1,27,500) %

⇒ R = 4 %

Therefore,

Rate of simple interest (R) = 4%
