Answer:
THE PERSON CLIMBS 5m AND SLIPS 1m 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
