Answer 1

The number of jumps required to reach the top of the pole is what?

Answer 2

exactly
that's my question

Answer 3

Well so basically in other terms we can say that the monkey only jumps 1 meter every jump

Answer 4

Since every jump he moves up 2 meters but slips 1 meter which is 2-1=1

Answer 5

Oh haha I read that wrong!..Im sorry.. but swiss girl is right.

Answer 6

So we can model our equation as follow 2x-x=12
Or (2-1)x=12
and then solve for x

Answer 7

or x=12

Answer 8

It takes 11 jumps. He won't slip from 12 to 11 on the last jump because he's already at the top. You are basically counting the elements in the following:

2, 3, 4, . . . , 12

which is 11

each element is the position before the slip but after the jump.

Answer 9

well, why would a monkey be jumping on a bare pole anyway? is not like it has figs or bananas, so really on every jump the monkey is wasting 2 meters plus momentum of eneergy :P
