Question

What principal will amount to Rs. 900 in 5 years at the rate of 10% per annum?

Answer 1

Answer:

The principal amount to Rs. 900 in 5 years at the rate of 10% per annum is rs 600.

Step-by-step explanation:

Given :

Rate R = 10%

Time (n) = 5 years

Amount (A) = 900

P = ?

Now  

$Interest I = \frac{(P\times N\times R)}{100}\\= \frac{(P\times 5\times 10)}{100}\\= \frac{(P\times 50)}{100}\\= \frac{(P}{2}$

Now  

$amount = Principle + I\\ p + \frac{(P}{2} = 900\\ \frac{(3P}{2} = 900\\ 3p = 900 (2)\\ 3p = 1800\\ p = \frac{(1800}{3}\\ p = 600$

So, principal amount is rs 600.

Answer 2

As per the data given in the question

In above question it is given that ,

We have determine the value of given

Given data in question P=$900$ ,R=$10$, T=5 , find the value of I

Where , we know that

P=principle

R= rate of interest

T=time

We get ,

$I=\frac{P\times R \times T}{100} \\I=\frac{900\times10\times5}{100} \\I=90\times10\times5\\I=450$

As a result ,we will need a solution is I=$450.$
