Answer 1

Answer :

Given :

Simple Interest = 3300

Rate = 8%

Time = 4 years

Required to find :

1. Principal Amount

Solution :

What is principal amount ?

In simple terms , we can that the amount of money which we had taken loan is also called as principal amount .

For example : If a person lends some 300 rupees from a bank . Then the amount taken from the bank on a loan will become the principal amount .

Formula :

$simple \: interest \: = \: \frac{principal \times rate \times time \: period}{100}$

Therefore,

By using this mentioned formula we can find the value of the principal amount.

Before that ,

Let the principal amount be " x "

Hence,

Now substitute the given values and so as to found the value of x .

$3300 = \frac{x \times 8 \times 4}{100} \\ \\ 3300 = \frac{32x}{100} \\ \\ 3300 = 0.32 x \\ \\ 0.32x = 3300 \\ \\ x = \frac{3300}{0.32} \\ \\ x = \frac{3300}{0.32} \times \frac{100}{100} \\ \\ x = \frac{330000}{32} \\ \\ x = 10312.5$

Therefore,

The principal amount = x = Rs 10312.5
