Hint: Perform the operations on the decimal values carefully. Solving two at a time can minimise errors.

We have the given expression as
$34.667 - 15.597 - 8.491 - 0.548 = ?$
Let us assume the missing term to be $x$, then we have
$34.667 - 15.597 - 8.491 - 0.548 = x$
$34.667 - 15.597 - 9.039 = x$
$34.667 - 24.636 = x$
$\therefore x = 10.031$
Hence, the required solution is $(b){\text{ 10}}{\text{.031}}$.

Note: To solve these types of questions, assume some value for the asked sign and substitute it in the given equation to obtain the required solution.
