Question

On a certain sum the interest paid after 3 years is rupees 450 at 5% rate of interest per annum find the sum​

Answer 1

Answer:

Let the principle or the sum be P.

Rate=5%,Time=3 years and interest=Rs450.

We know,

S.I=PRT/100

Therefore,Rs450=(P*5*3)/100.

or,Rs450=3P/20

or,P=(Rs450*20)/3

or,P=Rs9000/3

P=3000
