Answer
a. $36 \ \Omega V$.
b. $396 \ \Omega$.
c. $324\ \Omega.$
d. $72 \ \Omega$
Work Step by Step
a. The silver fourth band indicates a tolerance of $\pm10\%$:
$$10\% \times 360 \Omega = (0.10)(360 \Omega) =36 \ \Omega V.$$
That is, the tolerance is $36 \ \Omega $.
b. The upper limit is
$$36 \ \Omega +360\ \Omega=396 \ \Omega.$$
c.The lower limit is
$$360\ \Omega-36 \ \Omega=324\ \Omega.$$
d. The tolerance interval is then $$
396 \ \Omega-324\ \Omega= 72 \ \Omega
.$$
