Surplus Funds

by sanju09 » Mon Feb 02, 2009 5:47 am
A school district deposited surplus funds totaling $90,000 into two separate accounts for a period of one year. Part of the $90,000 was put into an account earning 3 percent simple interest and the rest into an account earning 5 percent simple interest. How much was put into the account earning 3 percent simple interest?

(1) The amount deposited by the school district into the account earning 5 percent was twice the amount deposited into the account earning 3 percent.

(2) The total interest earned on the $90,000 for the year was $3,900.

IMO D

I agree with D.

1) $90,000 was deposited in the ratio 2:1 for 5%act to 3% act so 2/3(90,000) in the 5% act and 1/3(90,000) in the 3% act. So $30,000 in the 3% act. SUFFICIENT

2) Since the total = 90,000, lets say that x = my in the 5% act then 90,000-x = the amt in the 3% act.

.05x = .03(90,000-x) = 3900

one variable, one equation, we can solve, hence 2 is SUFFICIENT.

Answer = D

What is OA?
