In what time will Rs 400 amount to Ra 512 if the simple interest is
the calculated @14% p a ?

Punya Purushottam · Accepted Answer

Principle=400
Amount=512
Interest=Amount-Principal
=512-400
=112
Interest=14percent per annum
Let year=x
Then
SI=P*R*T/100
112=400*14*x/100
112=4*14*x
112=56x
x=112/56
=2 years

So it will take 2years

In what time will Rs.400 amount to Ra.512 if the simple interest is the calculated @14% p.a.?
