Answer / pankaj kumar garg

Let the speed of escalator be x steps/sec

then total steps in escalator is 26 + 30x (since the
escalator covers 30x steps while the person covers 26 steps)

Similarly the in the second case the total no of steps is 34
+ 18x

solving both .. 26 + 30x = 34 + 18x

12x = 8 , x = 2/3 therefore steps is 26 + 30*2/3 = 46 steps

Answer / siva

If he walks 26 steps , he requires 30 sec to reach bottom. If he walks 34 steps he requires 18 sec to reach bottom.
So walking (34-26)=8 steps he requires (30-18)= 12 secs.
In one sec he walks ( 8/12)= 2/3 steps
34 steps requires 18 sec
so 2/3* 18 =12
In remaining 18 secs he walks 12 steps 34+12 = 46 steps

Answer / nils

Steps - 26 => 30Sec
Steps - 34 => 18 Sec
=> 8 steps -> 12 sec ....(1)

=> 26 steps -> 39 sec
& 34 steps ->51 sec

So total time without walking it will be 39 + 30 = 51+18
=69 sec

so steps = 48 ....from (1)
