420*100 = 42000,
42000 / (divide)105=400.
42000 / (divide)105=400.

B.G= S.I on T. D.
B.G=(T.D*R*T)/100.
B.D-T.D=(T.D*R*T)/100.
T.D+(T.D*R*T)/100=B.D.
T.D(100+R*T)/100=B.D.
T.D=B.D*100/(100+R*T).
B.G=(T.D*R*T)/100.
B.D-T.D=(T.D*R*T)/100.
T.D+(T.D*R*T)/100=B.D.
T.D(100+R*T)/100=B.D.
T.D=B.D*100/(100+R*T).

I = P*N*R.
Here I = Interest.
P = Capital.
N = Time.
R = Rate.
Let capital=x.
(420-x) = x*(4/12)*(15/100).
x = 400 answer.

Here T stands for Time or Number of Years.
Why T = 1/3?
Because we can write 4 months as 1/3 years. (Ref: 4/12 = 1/3)
