On a certain sum the simple interest paid after 3 years is rupees 450 at 5% rate of interest per annum.Find the sum at the end of 3 years.

Answer 1

Intrest=450
Rate=5%
Time=3 years
Principle=?

Principle=(Intrest*100)/(Rate*Time)
=(450*100)/(5*3)
=45000/15
=3000

therefore
sum paid after 3 years=3000+450
=3450
