Question

what will be the amount of interest of 300rs.for 6 month if the rate of interest is 10% per annum

Answer 1

Answer:

Let the original rate be R percent per year, the principal amount be P, time T

Given is SI = 600 = P * R * 10 / 100

Hence P*R = 6000

SI for first five years will be 300 at the end of first 5 years.

When P is trebled for next five years, the SI for those five years will be = 3P * R * 5 / 100 = [ 15* P * R ] /100 = [ 15 * 6000 ] / 100 = 900

Hence the total interest will be 300 + 900 = 1200

I Hope it will help!
