Escalator Questions | Time Speed Distance | AP HP Trick | SSC CGL 2026 Maths | CAT PYQ
इस वीडियो में हम Escalator Based Questions को एक बहुत ही आसान और powerful concept से solve करेंगे.
अगर किसी व्यक्ति की speed B है और escalator की speed S है, तो तीन possible speeds होंगी:
B − S, B, B + S
ये तीनों speeds A.P. में होती हैं.
और क्योंकि Distance same है, इसलिए इनके respective Times H.P. में होंगे.
अगर extreme times X और Y दिए हैं, तो middle time होगा:
Middle Time = 2XY / (X + Y)
इसी एक concept से कई Escalator Questions सिर्फ कुछ seconds में solve किए जा सकते हैं.
इसके अलावा वीडियो में Total Number of Steps वाले Escalator Questions भी detail में समझाए गए हैं.

QUESTIONS COVERED IN THIS VIDEO
━━━━━━━━━━━━━━━━━━
Q1. A man can walk up a moving-up escalator in 30 seconds. The same man can walk down the same moving-up escalator in 90 seconds. How long would it take him to walk up the escalator when it is not moving?
CHSL Prelim 2025 / CAT 1995
(a) 45 seconds
(b) 75 seconds
(c) 60 seconds
(d) 40 seconds
Q2. Elvish is going up the escalator. It takes Elvish 80 seconds to walk up the escalator which is moving upwards and 120 seconds to walk up the escalator which is moving downwards. Calculate the time taken by Elvish to climb the escalator which is stationary.
(a) 80
(b) 88
(c) 96
(d) 100
Q3. A passenger is walking on an escalator at a speed of 6 km/h relative to the escalator. The escalator is moving at 3 km/h relative to ground and has a total length of 120 m. The time taken by him to reach the end of the escalator is?
(A) 16 s
(B) 48 s
(C) 32 s
(D) 80 s
Q4. A person takes 60 seconds on an escalator which is moving down when he walks down, but takes 40 seconds when he runs down. He takes 20 steps when he is walking whereas he takes 30 steps when he is running. What is the total number of steps in the escalator?
(a) 40
(b) 50
(c) 60
(d) 30
Q5. Neetu and Rakesh are climbing on a moving escalator that is going up. Neetu takes 10 seconds to reach the top but Rakesh takes 8 seconds to reach the top. This happens because Rakesh is faster than Neetu. Rakesh takes 4 steps whereas Neetu can take only 3 steps in one second. What is the total number of steps in the escalator?
(a) 30
(b) 40
(c) 35
(d) 45
Q6. Aryan and Kelvin are climbing on a moving escalator that is going up. Aryan takes 60 steps to reach the top but Kelvin takes 64 steps to reach the top. Aryan can take 3 steps in a second while Kelvin can take 4 steps in a second. Calculate the total number of steps in the escalator.
(a) 60
(b) 80
(c) 88
(d) 76
Q7. Shyama and Vyom walk up an escalator (moving stairway). The escalator moves at a constant speed. Shyama takes three steps for every two of Vyom’s steps. Shyama gets to the top of the escalator after having taken 25 steps, while Vyom, because his slower pace lets the escalator do a little more of the work, takes only 20 steps to reach the top. If the escalator were turned off, how many steps would they have to take to walk up?
CAT 2021
(a) 40
(b) 50
(c) 60
(d) 80
━━━━━━━━━━━━━━━━━━
IMPORTANT CONCEPT
━━━━━━━━━━━━━━━━━━
If speeds are:
B − S, B, B + S
then speeds are in A.P.
Therefore, for the same distance, corresponding times will be in H.P.
If two extreme times are X and Y:
Required Middle Time = 2XY / (X + Y)
For Total Steps Questions:
Total Steps = Steps taken by Person + Steps covered by Escalator
