Question

Find the Principal. If Interest = 1239 Amount = 7282. tell me principal ​

Answer 1

Step-by-step explanation:

Let the principal amount be equal to P. Let the rate at which the interest is levied is equal to R% per annum (per year). let the time for which the amount is lent = T years. Then we can write:

Simple Interest = [{P×R×T}/100]

We can also calculate the Principal amount as P = [{100×(Simple Interest)}/(R×T)].

Similarly, we can write the time T as equal to T = [{100×(Simple Interest)}/P×R].

Now let us solve some examples to get acquainted with these formulae.
