Hello students, we are given a question here that an engineer deposits $1 ,000 into an account.
00:09
Here we are given, sorry, $10 ,000 into an account when the market interest rate is given as 10 % per year.
00:16
And the inflation rate is given as 5 % per year.
00:20
If the account is left undisturbed five years, then we are given here some questions.
00:26
First is, how much money will it be in the account? so since we are supposed to know that here, what we are given, the principal amount p is given as here, $10 ,000 and the market interest rate is given as here we can just say that market interest rate which is r is equal to 10 % per year, inflation rate i is given as here 5 % per year, okay? and undisturbed time is 5 years, it means t is equal to 5 years.
00:59
Now here we are supposed to know that we need to calculate first of all the real rate of return so basically real rate of return is equal to 1 plus r 1 plus r divided by 1 minus sorry 1 plus i students minus 1 so 1 plus r is 10 percentage it means 0 .1 divided by 1 plus i is 5 percentage it means 0 .05 and then minus 1 okay, students.
01:29
So basically it should be like here we can say that the 1 .1 divided by 1 .05 minus 1.
01:38
So basically 1 .1 divided by 1 .05, okay, students then minus 1...
