i think it is a confused question, A will increase B, we usually understand it as B will be added into A?
according to your understanding, it should be A-B=B*3
i do think there is mistake in the understanding of the question itself

But the question:  A will increase B by 300 percent.==> A+B=4B same as A=3B
A

cook:
increase by不是表示“升高了多少”的意思吗？

cook

I change to A=3B

pgclt

B increases by 300 percent: B->4B.  
A equals to new B: A=4B.

B increases to 300 percent: B->3B.  
A equals to new B: A=3B.

到底那个答案正确，我都被弄糊涂了，斑竹说句话把

How about A+B=300%B ,?
