Answer 1

Principal - ?
Time - 4 years
Rate - 6%
Interest - ₹1200

S.I = PxRxT/100
1200 = Px6x4 / 100
1200x100 / 6x4 = P
₹5000 = P

Answer 2

Principal Amount = Rs 5000

Simple interest is a quick and simple technique of calculating interest on money. Interest is always applied to the initial principle amount under the simple interest method, and the rate of interest is the same for each time cycle.

Simple Interest amount is usually calculated by multiplying the principal amount, the rate of interest and time period.

Thus,

Given, Simple Interest = Rs 1200

Rate of Interest = 6% per annum

Time period = 4 Years

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

∴ Simple Interest = $\frac{Principal*6*4}{100}$

∴ Principal Amount = $\frac{1200*100}{6*4}$

∴ Principal Amount = Rs 5000
