Question

I ll mark as brainest 1 Ans please help with formula

Answer 1

Now simple ineterst = P×R×T/100 So , amount - principal = 12500×R×4/100 15500-12500=50000R/100 3000=500r R=3000/500=6 So (a) is correct

Answer 2

difference(Si)=15500-12500

                 =3000

LET rate be x

3000=12500*x*4/100

3000=1000x

so rate=3%
