Remaining money that was invested in government certificate = (1 - 1/2 - 1/4 - 1/5) = 1/20 of the total money.

Hence, 1/20 of the total money = $10.000
Hence, total money = $(20*10.000) = $200.000

The correct answer is C.

C.$200.000
D.$500.000
E.$2.000.000
let the initial amount be x;
1/2=50%; 1/4=25%; 1/5=20%;
which upon adding becomes 50%+25%+20%=95%;
so remaining 5% is=10;
(5/100)x=10;
x=200; hence C

We can plug in the answers, which represent the total amount of the trust fund.

Answer choice C: 200,000
Stock investment = 1/2 * 200,000 = 100,000.
Bond investment = 1/4 * 200,000 = 50,000.
Mutual fund investment = 1/5 * 200,000 = 40,000.
Total investment thus far = 100,000 + 50,000 + 40,000 = 190,000.
Amount remaining for government certificate = 200,000 - 190,000 = 10,000. Success!

The correct answer is C.

C.$200.000
D.$500.000
E.$2.000.000
If we let T = the total amount of the trust fund, we can create the following equation:

(1/2)T + (1/4)T + (1/5)T + 10,000 = T

Multiplying the entire question by 20 gives us:

10T + 5T + 4T + 200,000 = 20T

19T + 200,000 = 20T

200,000 = T

Answer: C
