Linda put an amount of money into each of two new investments, A and B, that pay simple annual interest. If the annual interest rate of investment B is 1.5 times that of investment A, what amount did Linda put into investment A ?
(1) The interest for 1 year is $50 for investment A and $150 for investment B.
(2) The amount that Linda put into investment B is twice the amount that she put into investment A.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
这个需要实际算下,发现都不行
求来求去也只能求出本金 A 和本金 B 的比值,没法得具体数值。
