不知道正确答案是什么，个人理解，LZ看对不对吧
第一题我选C，应该是这样的：
因为今年公司的quarterly earnings是 $1.10 per share > expects quarterly earnings of $0.80 per share
所以今年的红利分两部分：
（1）预期部分（half of which will be distributed as dividends to shareholders）：0.8×50%×200
（2）附件部分（an additional $0.04 per share for each additional $0.10 of per share earnings）：0.04×[(1.1-0.8)/0.1]×200
两部分加起来就是104
第二题我选A
设去年年利率为R，根据题意：R(1+10%)=1%
解出来R=0.9090909……%≈1%
