Answer 2

Given,

S.I. of 5 years at the rate of 6 % is rupees 90

To Find,

The principal amount =?

Solution,

We can solve the question as follows:

It is asked that we have to find on what principal do we get a simple interest of Rs. 90 at 6% in 5 years.  

$Simple\: interest = Rs.\: 90$

$Time = 5\: years$

$Rate = 6$%

The formula for finding the simple interest is given as:

$Simple\: interest = \frac{Principal*Rate*Time}{100}$

Substituting the given values in the above formula,

$90 = \frac{Principal*6*5}{100}$

$90 = \frac{Principal*30}{100}$

$Principal = \frac{90*100}{30}$

$Principal = 3*100= Rs.\: 300$

Hence, the principal amount is Rs. 300.
