Each M-type memory unit will increase the base memory capacity of a certain computer by 3 megabytes. What is the base memory capacity, in megabytes of the computer?

(1) 2 M-type memory units will increase the computers base memory capacity by 300 percent

(2) The memory capacity of the computer after 2 M-type memory units are added to the base memory capacity is 1.6 times the memory capacity of the computer after 1 M-type memory unit is added to the base memory capacity.

答案：D 可是我是连题意都没有看懂，谁能帮我翻译一下？

试着解释一下:

suppose: base memory capacity: x

then: (1) (x+3)*2=3x

(2) x+6=1.6(x+3)

分别可以计算出x.
