Indicate all the possible lengths of the number line described above.

A- 10

B- 18

C- 22

D- 24

E- 27

F- 30

G- 36

H- 117

I- 130

What's the source of this question?

I ask because I don't understand why B, D and E aren't among the answers.

If p = 3, then the measurements are 3, 6, 9, 12, 15,

18, 21,

24,

27 etc

Cheers,

Brent
