Chapter 8, Problem 5RQ

Refer to Figure 8-21. Assume that the resistors have the following values:

$\begin{array}{l}\begin{array}{l}{\text{R}}_{\text{1}}\text{= 150 }\Omega \hfill \\ {\text{R}}_{\text{2}}\text{= 120 }\Omega \hfill \\ {\text{R}}_{\text{3}}\text{= 47 }\Omega \hfill \end{array}\\ {\text{R}}_{\text{4}}\text{= 220 }\Omega \end{array}$

Assume that an ohmmeter connected across the entire circuit indicates a value of 245 $\Omega$. Does this reading indicate that there is a problem with the circuit and, if so, what is the most likely problem?
