You want to invest $20,000 today to accumulate $32,000 for graduate school. If you can invest at an interest rate of 10% compounded annually. To find how many years will it take to accumulate the required amount, you would search the 10% column in the:

N = 5 years

Explanation:

At first we have to calculate the number of periods to determine at which part of the table we should look at.

Given,

PV = $20,000

FV = $32,000

Interest rate, i = 0.10 (10%)

Number of periods, n = ?

We know, Future value, FV = PV ×

or, $32,000 = $20,000 ×

or, 1.6 =

As the factor is 1.6, we will look at the following image which is the FV factor table to find the number of periods.

We can find it in a different way too.

log 1.6 = n log 1.10

or, n =

or, n = 4.93 years

Therefore, n = 5 years

if it is for a job, then you should learn everything you can about the job, like what does it involve, what qualification is required and how you are the right person for that job. dress appropriately for the interview. get plenty of rest the night before. good luck!
