He then climbed 20 steps all the way to the top of the ladder and got off on the roof. How many steps are there on the ladder?

32

Then, he came back down 14 steps, so the total number of stairs from the ground he climbed .

Remaining steps

Given that he climbed 20 steps all the way to the top of the ladder which is equal to the remaining steps. So,

Hence, there are 32 steps on the ladder.

the correct answer is 5
