Question

Simple interest on a certain sum 4/25 of the sum, if both the rate of interest and time are equal. Find the rate of interest?

Answer 1

hey mate

here is your answer ✔️✔️✔️

let the sum be x

SI=4x/25

let the time =Tyears

and rate =T%

we know that SI=(P×R×T)/100

=4x/25=(x×T×T)×100

=4x/25=T^2x/100

=4/25=T^2/100

=400=25T^2

=400/25=T^2

=16=T^2

=T=4

time =4years

rate=4%

hope it's helps
