Hello students, we are given a question here to achieve 13 percentage rate of return.

How much would you need to be invested today in an investment which returns 12 ,000 at the end of the three years and the 10 ,000 at the end of the five years? so here we are supposed to know that it should be like you can write here that the a is equal to there is a formula is equal to p times 1 plus r divided by 100 whole power is t students so basically a comes out as equals to first we will start for the twelve thousand dollar so twelve thousand times one plus here we can just say that sorry here what we need to do for 12 ,000 we can just write the amount after three years is 12 ,000 so 12 ,000 is equal to p times let's say this is p1 plus one plus times 1 plus 13 divided by 100 whole power is three years it is 3.
01:01
Okay, students now 12 ,000 is equal to p1 times it will be 1 .13 whole cube.
01:09
So p1 is equal to 12 ,000 divided by 1 .13 whole cube.
01:16
Okay, so what we will get here p1 is equals to it will be 830016 .60.
01:27
Okay students now we will go to similarly we we will go to the second part for 10 ,000 okay for the 10 ,000 so basically we can just say that again 10 ,000 is equal to p2 times of again 1 plus 1 plus 13 divided by 100 and whole power is now it will be 5 because of the 5 years so basically 10 000 is equal to p2 times 1 .13 whole power is 5 okay, students, so p2 is equal to 10 ,000 divided by 1 .13 whole power is 5.
02:05
So it comes out as equals to p2 is equal to now, 10 ,000 divided by 1 .13 whole power 5...
