Question #47556

Mother Zeta has two types of deposits. Deposits of both the magnitude of the first two deposits. The first deposit rate 10% p.a. and 12% second deposit. If the total interest earned from the two deposits of Rp 33.4 million a year, how much of each deposit?

Expert's answer

A time deposit is a money deposit at a banking institution that cannot be withdrawn for a certain "term" or period of time (unless a penalty is paid).

The formula of simple interest is:

FV = PV*(1 + i*t), I = PV*i, where PV - initial sum, i - interest rate, t - number of periods, interest earned.

In our case:

I1*0.1 + PV2*0.12 = 33.4

I1 = 334 - 10*PV2

If the initial sums of deposits are different, there is not enough information to calculate them.
