1) Let us write by calculating the number of yrs for which the interest of Rs 600 at the rate of Simple Interest of 8% per annum will be Rs 168.
Answers
Solution :
Let us assume that the number of years for which the interest is compounded is x years .
The interest which is being calculated here is Simple Interest .
The rate of the simple interest is 8% per annum .
The given principal invested is Rs. 600 .
The required interest obtained is Rs. 180
As we know ,
In Simple Interest :
SI = [ Principal × Rate × Time period ]/100
=> SI = [ 600 × 8 × t]/100
=> SI = 48t
SI = 168
=> 3.5 years .
Thus , the required time period is 3.5 years .
This is the answer.

Additional Information :
In compund interest
A = P ( 1 + r/100)^t
Where p is the principal
r is the rate percent
t is the time period
A is the amount
