Question A person walks up a stalled escalator in \( 90 \mathrm{sec} \). He is carried in \( 60 \mathrm{~s} \), when standing on the same escalator which is now moving. The time he would take to walk up the moving escalator will be:-
(A) \( 27 \mathrm{~s} \)
(B) \( 72 \mathrm{~s} \)
(C) \( 18 \mathrm{~s} \)
(D) \( 36 \mathrm{~s} \)πŸ“²PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
