Solution:
we are given that
Kathy stood on the middle rung of a ladder.
Since she climbed up 44 rungs, moved down 33 rungs...total up move of 44-33=11 rungs
Then climbed up 99 rungs. so a total of 11+99=110 rungs up.
Then she climbed up the remaining 33 rungs to the top of the ladder so total up move by 110+33=143 rungs
Since Kathy stood on the middle rung of a ladder so number of rungs=143x2=186
Now add the middle rungs.
Total number of rungs in the whole ladder=186+1=187
