Question

the interest to be paid after 3 years on the principal Rs2500 at 12% rate of interest is

Answer 1

we know 
S.I= RXTXP/100
Here R=12,T=3 and P=2500
so SI=12x3x2500/100
        =12x75
         =900
SI=900

Answer 2

T= 3 years
P= ₹2500
R = 12%
I=PRT/100 =2500×12×3÷100 =2500×12×3/100 = ₹900
