You are standing on a middle rung of a ladder. If you first climb up 3 rungs, then down 5 rungs, and then up 10 rungs, how many rungs are on the ladder?

Respuesta :

Answer:

The total number of rungs on the ladder are 16 rungs .

Step-by-step 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 [tex]\dfrac{x}{2}[/tex] = 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
