问题如下：
A manger entered into a receive-fixed and pay-equity swap three months ago. The annualized fixed rate is 3% and equity index was at 100 when swap was entered. The maturity of swap is one year with quarterly reset, and notional amount is $100 million. The current spot rates are as follows:
The value of this equity swap would be zero if the equity index level is:
选项：
A.100.753630
B.100
C.99.753630
解释：
A is correct.
考点：equity swap求value
解析：
与上一题一样，本质还是求value，只不过已知value=0，反求此时equity index的价格。
在上题中我们已经计算出fixed leg的价值=100,753,630
将现在index的价格设为X，那么equity leg的价值=X/100*100,000,000
头寸是付equity return收固定，所以value of swap=- X/100*100,000,000+100,753,630=0
可计算出X=100.753630
请问老师，答案里面的上一题是哪一题。。。。麻烦给个过程谢谢
