Concept:
Simple Interest: It's the type of interest which is calculated on the principal amount and remains constant for every year.
Principal amount is the original amount invested in a investment.
Rate of interest is the rate at which the simple or compound interest is being calculated.
Given:
We are given that:
The sum becomes k times itself in 16years and 2k times in 40 years.
Find:
We need to find that in how many years, it will become 4k times itself.
Solution:
Let the amount of sum invested to be x at interest rate of y%
ATQ:
The sum of money increases fro k to 2k times in (40-16) years.
That is the increase in money by 2 times is in 24 years.
So, the increase in money by 4k times from 2k times will be:
t=40+24
t=64 years.
Therefore, it will require 64 years to make the money 4k times.
