Question

if a cirten a sum amounts to 6 times itself at the 25% p.a. simple interest in 5k year then find k

Answer 1

we know that
simple interest =PTR/100
Where ,
P=principal
T=time
R=rate
its states that the sum amounts to 6times out of that 1time is principal....so the SI is 5 times of principal



so substitute values....in equation
5P=P(5K)*25/100...
solving that we got K=4...
hope it is helpful
