To answer your question, the value of the expression is $$\frac{103}{28}$$ or approximately 3.68. Here is a detailed solution:

$$ \begin{aligned} 4-\left(\frac{41}{84}-\frac{5}{21}\right)+7+\frac{11}{30} &= 4-\frac{41-20}{84}+7+\frac{11}{30} \\ &= 4-\frac{21}{84}+7+\frac{11}{30} \\ &= 4-\frac{1}{4}+7+\frac{11}{30} \\ &= \frac{16}{4}-\frac{1}{4}+\frac{28}{4}+\frac{11}{30} \\ &= \frac{43}{4}+\frac{11}{30} \\ &= \frac{1290}{120}+\frac{44}{120} \\ &= \frac{1334}{120} \\ &= \frac{667}{60} \\ &= \frac{103}{28} \end{aligned} $$
