I think the question is ambiguous and not correctly worded.
Explanation:
Total force applied
=
47
N
Assuming that direction of movement of pencil and applied force is same.
Work done by force in moving the pencil
W
=
Force
×
Distance through which force moves
⇒
W
=
47
×
0.25
=
11.75

In case we are asked useful work done then we calculate net force used for pushing the pencil:
Net force used for pushing the pencil
=
47
−
23
=
24
N
Assuming that direction of movement of pencil and net force is same.

Answer:
Formula = work multiply displacemenat
W = F×S
W = 47 × 0.25
- W = 11.75
