Question

At 10% C.I. p.a., a sum of money accumulate to Rs. 9625 in 5 years. The sum initially invested is?

Answer 1

Let the initial sum d:

The sum at any year (y) with C.I.P.A (c) and final accumulate (s) is given by:

\[d + \frac{ c }{ 100 } d * y = S\]
\[d + \frac{ 10 }{ 100 } d * 5= 9625\]


\[1.5d = 9625\]

Answer 2

If you started with d money and you get each year 10 percent of that amount so

finally you will have your inital investment + amount gained each year
we gain 10 percent = 0.1d (10/100)

d + 0.1d * (years) = total now.
