Let the sum be x

Simple Interest=3x/5

Rate= 100×S.I.÷Sum×Time

=100×3x÷x×5×5=12% p.a.

Simple Interest=3x/5

Rate= 100×S.I.÷Sum×Time

=100×3x÷x×5×5=12% p.a.

The Brainliest Answer!

the principal amount (p)= x

time(t)= 5

rate = r

simple interest = I

I = PTR /100

3/5 x = 5 ( x) (r)/100

5xr /100 = 3/5 x

r/20 = 3/5

5r = 60

r = rate percent = 12%
