Answers
In the above Question , the following information is given -
A person was climbing on a building .
He slips 1m for every 5m he climbs up .
The building is 53m high .
He takes 5 seconds to climb 1m .
Solution -
He takes 5 seconds to climb 1m .
So , to climb 5 m , he takes 25 seconds.
Now , he slips 1 m for every 5 m he climbs up .
So , this can be stated as -
He , can climb 4 m in 25 seconds.
The building is 53 m high.
Now ,
He , can climb 4 m in 25 seconds.
To climb 48 m , he will take 25 × 12 seconds = 300 seconds.
Now , 8m is left .
For the next 4 m ,
He will take 25 more seconds.
Total time taken till here - 325 seconds .
Now , he has to climb 3 m more and he won't slide back again as he has already reached the top .
He takes 5 seconds to climb 1m .
So , to climb 3 m , he takes 15 seconds.
Thus , total time taken by him to climb the building -
=> 325 seconds + 15 seconds
=> 340 seconds .
=> 5 minuites and 40 seconds.
This is the required answer.
