Answer:
The total number of rungs on the ladder are 16 rungs .
Explanation:
Given as :
At first the climb up number of ladder = 3 rungs
At second the climb down number of ladder = 5 rungs
At third the climb up number of ladder = 10 rungs
Let The total number of rungs on the ladder = x
Now, According to question ,
The total number of climb up ladder = First + Third
I.e The total number of climb up ladder = 3 + 10 = 13 rungs
And The total number of climb down ladder = 5 rungs
So , From the middle of rungs = total number of climb up ladder - total number of climb down ladder
I.e
= 13 rungs - 5 rungs
∴ x = 8 × 2 rungs
I.e x = 16
Hence The total number of rungs on the ladder are 16 rungs . Answer
