# a person was climbing on a building. He slips 1m for every 5m he climbs up. If the building is 53m high and he takes 5 seconds to climb 1m, find the total time taken by him to get on the top of the building..

TO CLIMB Im HE TAKES 5 SECONDS

SO FOR 5m HE TAKES 5x5= 25 SECONDS

AS HE SLIPS 1m FOR EVERY 5m CLIMB

IN EACH ATTEMPT HE CLIMBS 5-1=4 m in 25 SECONDS

TOTAL HEIGHT OF THE BUILDING= 53m

SO HE WILL NEED 53/4= 13 (remainder 1 ignored as he will not slip after the last climb)

SO, TIME TAKEN TO CLIMB THE BUILDING = 25x13=325 SECONDS

ANS:: 325 SECONDS
