my soln to: let the focal date be six months from now.

[naveed_786110]

From this thread: A loan of $30,000 at 5% p.a. is to be settled in equal payments of 3 months, six months and nine months. Calculate the size of the equal payments and let the focal date be six months from now.

I solved it the following way.

Let x be the required amount.
The equation is

x(1+0.05 x 3/12) + x + x/ (1+0.05 x 3/12) = 30000

which gives x = 10,000.
