Hello students, it is given that the interest rate is 13 percentage per annum common unfortunately.
00:07
Here one year has 26 fortune.
00:09
So, the final amount of loan after certain period is a equal to p into 1 plus r by n power nt.
00:25
Here a is final amount, p is a principal and r is the rate of interest per period and n is the number of times interest is compounded per year.
00:35
T is the time period of years.
00:37
So, let the principal be 100, then amount after one year is a equal to 100 plus 13 percentage of 100.
00:50
So, a equal to 100 plus 13, which is equal to 113.
00:58
And now substitute n equal to 26 and t equal to 1 and a equal to 113 into a.
01:05
So, we get 113 equal to 100 into 1 plus r by 26 into 1.
01:21
So, which is equal to 1 .13 equal to 1 plus r by 26 power 26.
01:30
Taking 26 root on both sides, so we get 26 1 .13 equal to 1 plus r by 26.
01:39
So, here 1 .0047117437 equal to 1 plus r by 26.
01:53
So, r by 26 equal to 0 .0047117437...
