问一道题：NO.PZ201511200300000801 第1小题

NO.PZ201511200300000801 £1,962,776. £1,994,447. B is correct. r* = r(1–ppiti–pcgtcg) = 0.06*[1–(0.30)(0.15)–(0.20)(0.35)–(0.40)(0.25)] = 0.0471 or 4.71 percent T* = tcg(1–ppi–pcg)/(1–ppiti–pcgtcg) = tcg(1–0.30–0.20–0.40)/[1–(0.30)(0.15)–(0.20)(0.35)–(0.40)(0.25)] = 0.0318 FVIFTaxable = £1,000,000[(1 + r*)n(1–T*) + T*] = £1,000,000[(1 + 0.0471)15(1–0.0318) + 0.0318] = £1,962,776 老师帮忙看看

NO.PZ201511200300000801 不存在unrealiaze capitgain吗 ？我看利息+分红+ capitgain占比之和为90%（30%+40%+20%），难道不应该计算还有10%的unrealiaze capitgain吗？这样才能保证各部分的占比之和为100%。

£1,962,776. £1,994,447. B is correct. r* = r(1–ppiti–pcgtcg) = 0.06*[1–(0.30)(0.15)–(0.20)(0.35)–(0.40)(0.25)] = 0.0471 or 4.71 percent T* = tcg(1–ppi–pcg)/(1–ppiti–pcgtcg) = tcg(1–0.30–0.20–0.40)/[1–(0.30)(0.15)–(0.20)(0.35)–(0.40)(0.25)] = 0.0318 FVIFTaxable = £1,000,000[(1 + r*)n(1–T*) + T*] = £1,000,000[(1 + 0.0471)15(1–0.0318) + 0.0318] = £1,962,776T*的分子部分视频就没听懂什么意思，麻烦老师一下T*分子部分t*（1-Pi-PPcg）含义是什么？我的理解是unrealizecapitgain的税收？但是为什么分子要用未实现的capitgain的税收，怎么理解

£1,000,000[(1 + 0.0471)15(1–0.0318) + 0.0318] 怎么算不出题目的数字啊，能否说一下计算器怎么按

FVIFTaxable = £1,000,000[(1 + r*)n(1–T*) + T*] 老师前面[(1 + r*)n(1–T*)我都看得懂，最后这个+ T*]为什么要加上去？
